The intent is to outline those principle areas that must be addressed and planned, in order to permit the continued coexistence between the oil industry and the community. ISSUES FACING THE CITY OF HUNTINGTON BEACH: 1. Why is there an increased detection of surface methane gas as outlined in the Roberti Report which may be threatening the safety of the community? 2. Is the current policy of building over or near active or abandoned oil wells a prudent policy? 3. Does the current oil well bond schedule protect the City? 4. What is the future of oil production in Huntington Beach? 5. What is the City's position on the future of consolidation projects? The following report addresses these issues and makes recommendations for City Council and staff action. Sincerely, "a d C. Picar ire Chief RCP/JM/sr L��cc: Paul E. Cook, Interim City Administrator 1099F a RECOMMENDATIONS AND ACTION SUMMARY METHANE GAS The position of the City should be to continue to monitor and gather informational data as to the quantity and source of the Methane Gas. Findings of the Roberti Study and subsequent reports find two specific problems and recommend certain preventative measures on a case by case basis. However, as the oil field becomes capped, additional repressurization problems may develop over the years. The Fire Department has developed an Emergency Operational Plan to respond to life threatening emergencies. The City Task Force has developed a Methane Action Program which is on schedule and should continue to be followed. BUILDING OVER OIL WELLS The position of the City should be to continue to pursue a cautious, prudent and well planned policy towards the construction of structures over abandoned oil wells. At present, Huntington Beach has in place one of the most advanced policies in the state. This position is not risk free but reasonable and prudent. OIL WELL SURETY BONDS At present, the coverage provided to the City by Surety Bonds with regards to oil wells is insufficient. Through City Council action, the coverage needs to be increased to $50,000 to provide the proper protection to the City. The present average cost of abandoning an oil well is $30,000 and the current surety bond is $10,000 per well. CONSOLIDATION PROJECTS: It should be the position of the City to encourage the "unitization and consolidation." This would accomplish several positive things: 1. Will reduce the number of oil wells and the public safety risk. 2. Will reduce blight and frees valuable land for other land uses. 3. Will allow the oil industry to extract oil as a valuable resource while insuring continued financial revenue to the City. 4. Would allow for the installation of much safer "state of the art" production facilities. 5. Would greatly reduce the number of oil operators and will make administration of the industry from a City standpoint more efficient. 6. Dovetails the modernization of the oil industry with the City's Redevelopment Plans. 1099F (10/87) TABLE OF CONTENTS I.

PREDICTING FUTURE OIL OPERATIONS VI-1 PREDICTING FUTURE OIL OPERATIONS VI-2 HUNTINGTON BEACH OIL FIELD CONSOLIDATION PLAN VI-5 OIL CONSOLIDATION AREA MAP VI-6 SUMMARY OF OIL OPERATORS VI-8 HUNTINGTON BEACH WELL COUNT HUNTINGTON BEACH OIL HISTORY The City of Huntington Beach overlies an old and very productive oil field which, since its discovery in 1920, has produced almost a billion barrels of oil. Although the field passed its production peak decades ago, it still produced enough oil during 1979 to rank seventh among all California oil fields in annual output. DISCOVERY WELL AND GOLDENWEST- GARFIELD AREA A series of discoveries, often in widely separated areas, led to the present day Huntington Beach Oil Field. Each discovery has been followed by a flurry in drilling activity, most of which, had little or no controls. According to George Hazenbush and Dennis Allen, oil was first discovered on May 24, 1920, when Standard Oil Company of California completed well "Huntington #Al" at a depth of 2,199 feet, producing 45 barrels per day of 14 gravity oil. This same well was subsequently deepened to 2,381 feet and produced 70 barrels of oil per day after deepening. However, and according to the same authors, it caused little excitement because of the low rate of production. In November of the same year, Standard Oil Company of California drilled what is generally considered the Huntington Beach discovery well. This well "Bolsa Chica #1," located near Reservoir Hill, was completed at a depth of 2,549 feet and came in flowing at the rate of approximately 2,000 barrels of 28 gravity oil per day. Shortly thereafter, Eddystone Oil Corporation completed "Ashton #1," at a depth of 3,455 feet, producing 1,300 barrels of 21 gravity oil per day. "Ashton #1" was located approximately one-half mile northeast of "Bolsa Chica #1." A flurry of drilling followed, which extended into the Goldenwest and Garfield area. This was the first of the closely spaced wells in the 4 Huntington Beach Field. After the drilling of 100 wells by various companies, and a total production of 119,000 barrels per day, drilling activity declined in this area by December, 1923. BARLEY FIELD AREA The next area of drilling activity, known then as the Barely Field Area and lying north- west of 23rd Street (Goldenwest Street) between Pacific Coast Highway and Clay Street, was developed slowly by the Standard Oil Company of California between 1922 and 1926. TOWNLOT AREA In April, 1926, drilling restrictions were lifted in the Townlot Area between 17th Street and 23rd Street which led to the discovery in July, 1926, of the Jones sand by the superior Oil Company when they completed "Jones #1" at 3,063 feet flowing at the rate of 472 barrels of 17 gravity oil per day. "Jones #1" is located at the corner of 22nd Street and Pacific Coast Highway. According to Hazenbush and Allen, this zone was probably the Stray sand, which is actually 350 feet above what is now commonly called the Jones sand. TOWNLOT AREA -LOWER OR MAIN ZONE In September, 1926, Wilshire Oil Company discovered what was called the Lower or Main Zone in the Townlot Area, when they deepened "H.B. #1" at the corner of 22nd Street and Walnut Avenue to a depth of 4,074 feet, flowing 700 barrels per day of 24.6 gravity oil. Intensive drilling activity followed, which led to some of the closest well spacing in California history. Many wells were drilled on 25 x 117-1/2 foot lots with production reaching a maximum of 63,400 barrels of oil per day from 78 wells in the area. 7008f (10/87) I-1 TOWNLOT AREA-TAR (BOLSA) ZONE During the development of the Lower or Main Zone in the Townlot Area, shallow oil sands were noticed while drilling some of the wells. In November, 1926, McKeon Drilling Company, Inc. completed "Dubois #1" at 1,952 feet, producing 200 barrels of 14 gravity oil per day. This completion led to another mild flurry of activity and a drilling campaign to develop the Tar (Bolsa) sands in the Townlot Area. TIDELANDS - The offshore pools were discovered in May, 1930, when the Superior Oil Company redrilled "Babbit #1" from the Townlot Area to an interval of between 3,838 and 4,313 feet producing 345 barrels of 26 gravity oil pr day. The reported production had increased to 1,450 barrels per day in August of the same year. Although this was considered unusual production from the Townlot Area, it wasn't determined until later that the well was bottomed in what was to be known later as the Tideland Pool. This well, located on 21st Street between Walnut Avenue and Pacific Coast Highway, is generally considered to be the discovery well of the offshore pool. This fact, however, was not generally known until Wilshire Oil Company completed "H.B. #15" on Pacific Coast Highway between 18th and 19th Streets, in July, 1933, flowing at the daily rate of approximately 4,800 barrels of 26 gravity oil. -The horizontal drift for this well was eventually determined to be in excess of 1,400 feet offshore from the Pacific Coast Highway. Other operators, including McVicar and Rood, developers of the "whipstock" (a tool used for directional drilling), soon began directing wells offshore and completing them in the tideland pool. This led to a temporary injunction being filed in September, 1933, by the State of California against one operator which carried an order that a directional survey be made of the well. This survey proved beyond question that the well was bottomed under State tidelands and brought about sliding scale royalty agreements between the State Land Commission and the operators producing from the State tidelands. In March, 1938, the legislature passed the State Lands Act and a new and far more orderly stage of offshore development followed. The first successful bidder on a tideland parcel offered by the newly created State Lands Commission was Southwest Exploration Company, now Wingle Companies, Inc. Their lease lies between the southerly prolonga- tion of 23rd Street (Goldenwest) on the southeast to a parallel line about one and one-quarter miles to the northwest and extends oceanward for one mile beyond the ordinary highwater mark. Orderly development began in 1938 with from 6 to 50 wells being drilled each year. There was an average of 452 producing wells in 1967 averaging approximately 60 barrels of oil per day for each well. The Main Zone is the principal producing interval, producing nearly three times as much oil as the Jones and from slightly over twice the number of producing wells. FIVE POINTS AREA Development of the Five Points area began in April, 1936, when Twentieth Century Oil Company completed "Schaaf-Bruce #1" on the south side of Ellis Avenue, east of Beach Boulevard. Completed in the upper Ashton Zone, low production rates and a thin zone kept activity in this area to a minimum and a major boom failed to materialize. SIGNAL -BOLSA LEASE The year 1940 saw Signal Companies, Inc developing the Signal-Bolsa lease which was an offset to the Standard-Bolsa lease. Although a productive area, its development was orderly and uneventful from a historical standpoint. 7008f (10/87) I-2 TOWNLOT AREA - UPPER TAR (MIDDLE BOLSA) In 1946 and 1947 interest was renewed in the Tar Zone (Bolsa) of the Townlot Area. O..L. Bolton drilled "Mize #1" at the corner of 20th Street and Orange Avenue in April, 1947. Completed in the upper Tar (middle Bolsa) Zone, this well initially produced 60 barrels of 13.5 gravity oil per day. .This produced another flurry of drilling, resulting in 136 new Tar Zone wells by April, 1949. Initial production of these wells varied between 10 and 100 barrels of 12.5 to 14 gravity oil per day. SOUTHEASTERLY EXTENSION OF TOWNLOT AREA Jack Crawford is generally_ credited with the discovery of the Southwesterly extension of the Townlot Area, however, A. L. Hunter, W. C. Bradford and D. R. Allen stated that it was Clark C. Peterson's redrilling of the abandoned well "Brower #1" in August, 1953, near the corner of Huntington Avenue and Chicago Street, which initiated the latest drilling flurry in Huntington Beach Field. This well flowed at an initial rate of 500 barrels of 28. gravity oil per day for 3 days, but production declined rapidly leading to the eventual abandonment of the well. The activity following completion of this well resulted in Jack Crawford, et al, drilling "Huntington #1" at the northeast corner of Atlanta Street and Huntington Avenue. "Huntington #1" was completed March 8, 1954 with an initial production of 200 barrels of 25.9 gravity crude per day. The latest flurry within the Huntington Beach Field was beginning! Encouraged by this success, Huntington Syndicate drilled and completed wells "Huntington Syndicate #2 and #3" to the west in the same Main Zone, each producing at the rate of 150 barrels of 26 gravity oil per day. Jack Crawford, et al, next drilled and completed the first Jones sand producer in this area. The well, "Huntington #5" was drilled in the vicinity of First and Olive Streets and started flowing January 1, 1955, at an initial rate of 735 barrels per day of 20.8 gravity oil. Now the boom was on in earnest! In rapid succession, 216 wells were drilled, of which, only 6 were nonproductive. However, because of the close spacing and rapid withdrawal of the oil and gas, production per well declined from approximately 500 barrels per day to 15 barrels per day in less than a year. Controls have been established through an oil code and through zoning which will lead to more orderly development if another oil producing area within the city limits is discovered. CURRENT PRODUCTION The current number of wells (1985) in the combined Huntington Beach oil fields are 1,952. Of these, 993 are producing, with 959 shut in or idle. In the year 1985, there were 8 new wells drilled; 1986, 1; and 1987, 2. For the year 1985, there were 7 abandonments; 1986, approximately 10; and 1985, 15. Daily production figures for 1985 were 22,030 barrels per day, with the well production average being 23.5 barrels per day. 7008f (10/87) I-3 TOTAL NUMBER OF WELLS (Thousands) — _ t•— ll.

In its pure form, it is colorless and almost odorless.- Although it is nontoxic, it is highly explosive in concentrations of 5 percent to 15 percent. It also acts as an asphyxiant, excluding oxygen from the lungs. Hydrogen sulphide often accompanies methane and causes the "rotten egg" smell. Highly toxic, it paralyzes the olfactory nerve at 100 PPM, rendering the victims incapable of assessing the danger they are in. At 500 .PPM or above, it causes loss of consciousness and eventual death. Methane and hydrogen sulphide are natural by-products of the decomposition of organic materials and of the formation of petroleum. Petrogenic or thermogenic methane is associated with the formation of petroleum. Biogenic methane is produced near the surface or in sediment depths of 300 meters or more. Measurable levels of biogenic methane can be detected in former or current swamp lands, river bottoms, landfill and sewers. All of the above sources exist in Huntington Beach. On March 24, 1985, a methane gas explosion and fire occurred at the Ross Dress-For-Less store in the Fairfax area of Los Angeles. The explosion occurred when methane gas was trapped in an unventilated room and ignited. The gas entered the building through small holes between the floor slab and foundation walls. Following the explosion, the gas and flames spread to cracks in the street, sidewalks and planter area. A pressure relief well was drilled to vent the gas in a controlled manner and reduce the concentration to below explosive levels. By 4:00 PM on March 26, all of the flames were out. As a result of the awareness created by the Fairfax incident, the Southern California Gas Company immediately notified the City in the Spring of 1985 that a potential for explosion existed in Huntington Beach when high methane readings were detected during routine inspection of their lines. The Gas Company determined that the gas was leaking from an outside source. Senator Roberti introduced SB 1458, which was signed into law by the Governor on September 23, 1985, after reviewing the Fairfax situation. The bill required the State Oil and Gas Supervisor to study abandoned oil and gas wells in areas where methane and other hazardous gases may accumulate to determine the locations and extent of hazardous gas accumulations, and to develop a plan to mitigate the problems. Huntington Beach officials requested that the City be included in the study to determine the source of our problems. On October 14, 1986, Senator Roberti announced the results of the study. One hundred ninety five (195) sites were tested in Huntington Beach. Twenty-three (23) of the sites were classified as "hazardous" and "dangerous." Although the test sites were located near known oil fields where abandoned wells exist, the methane gas was classified as biogenic in all sites except two (2). The biogenic determination is under discussion at this time. ISSUES The City of Huntington Beach must now develop a strategy, which will enable residents to safely coexist with the methane problem. Issues which must be resolved in cooperation with the Division of Oil and Gas and the City of Newport Beach include the sources of the gas, its method of migration; i.e., whether or not it is using oil wells as conduits, which agency has primary responsibility and liability for the problem, and the development of an immediate and long-term management strategy. 7008f (10/87) III-1 J The following program attempts to set a course of action for the City to follow until further information is available. If so approved and directed, the Methane Task Force, which is comprised of staff members from the Fire Department, Building and Planning Divisions, and Public Works will continue to implement the program and will submit revised programs for your review as necessary. 7008f (10/87) III-2 METHANE ACTION PROGRAM COMPLETION ESTIMATED* LEVEL DESCRIPTION DATE COST I PROTECTION OF LIFE, ENVIRONMENT, AND PROPERTY GOALS 1.

AUGUST 7, 1987 l 099F (10/87) III-15 INTRODUCTION Huntington Beach and Newport Beach were two cities included in the Roberti Report (SB 1458) entitled, "A Study of Abandoned Oil and Gas Wells and Methane and Other Hazardous Gas Accumulations" performed by GeoScience Analytical, Inc. (GSA) under the direction supervision of the Division of Oil and Gas (DOG), State of California. The DOG wanted to know if there was hazardous or dangerous concentrations of gas in near surface soils (3' - 8' deep) and if possible the source(s). The cities of Huntington Beach and Newport Beach were also interested in the origin of any hazardous gases (methane) and the mechanism of their transport to the surface. Since the original Report was issued, the cities of Huntington Beach and Newport Beach have contracted with GSA to undertake further sampling and analyses in an effort to determine the source(s) of surface methane and the most likely mechanism for its transport. Specifically GSA will attempt to answer two questions: (1) Is the source of the gas biogenic (bacterial; a "swamp" gas)?; or thermogenic, that is, the result of heat induced decomposition of buried organic matter; and, (2) How has it made its way to the surface? The sampling sites for the study were chosen by the cities in consultation with their geologists. The Roberti Report served as a reference. 1099F (10/87) 111-16 -31- SAMPLE SITES AND COLLECTION PROCEDURES HUNTINGTON BEACH The sample sites for the City of Huntington Beach were chosen by Mr. Mel Wright, City Consultant, and were of two types: soils and producing wells. The soil sites were some of the areas found during the original State survey to have high concentrations of methane 'as well as two unsurveyed areas thought to be similar (14 total sites). For the most part, these sites were private property and were surveyed using the soil probe (see Appendix I). Since it was highly unlikely that the exact spot sampled for the Roberti Report would be found, two soil probes were taken at each location, if feasible. In addition, a third sample was taken from a water meter box if available. Generally these are cement boxes open to the soil on the bottom with a cement lid flush with the ground sur- face. The lids have a small lifting hole in them which permits access but does not permit the gases in the box to circulate freely with the atmosphere. Using a gas tight syringe equipped with a six (6) inch #18 gauge needle that could be inserted through the lift hole, twenty (20)cc of gas was withdrawn from each enclosure and transferred to hydro- carbon free glass containers for transport to the laboratory. At two sites, Karales 2 and the intersection of Hamilton and Magnolia, samples were also collected with a two man hydraulically powered auger (see Appendix II). III-17 -32- Most of _ the area of the City of Huntington Beach that was of interest here lies over the West Newport Oil Field. A small part lies over the Sunset Beach Field. For this reason, Mr. Wright picked three wells within Huntington Beach to be sampled in addition to the two West Newport offshore wells owned by Newport Beach. The three wells were Karales 2 and Kernview 1 (Atlanta and Bushard) and Weaver-Community 1. The first two are in the West Newport Field and the latter is in Sunset Beach Field. All the wells were sampled by opening a small vent and letting the escaping production gas sweep the air out of glass stor- age vessels. Oil and water were also collected since they were swept along by the gas flow. III-18 .-33- CITY OF HUNTINGTON BEACH RESULTS AND DISCUSSION The majority of the gas hazard sites of concern in the City of Huntington Beach are within the boundaries of the West Newport Oil Field. The one exception is the Algonquin site situated within the Sunset Beach Oil Field. Counting the two tidelands wells owned by the City of Newport Beach, four wells were sampled for their produced gas within the West Newport Field and one within the Sunset Beach Field. The wells were sampled to gain information about the character- istics of possible gas sources in the problem areas. Three of the wells in the West Newport Field (Newport 3, tide- lands; Karales 2, south side of Brookhurst; and Kernview, Atlanta and Bushard) produced dry gas with CH comprising at least 98% of the vola- tile hydrocarbons. The fourth well, Newport 8 (tidelands) was very wet with CH accounting for only 60% of the volatile hydrocarbons. A full spectrum of gasoline range components was present in all four wells with Newport 8 having the greatest amount. The API gravity of the oils, ranging from 19 to 23 for the field as a whole, reflects the abundance of the lower end components. Certain ratios were calculated for the volatile hydrocarbons in the well gases to aid in their comparison and characterization. One useful calculation is the ratio iso-b/n-b, a measure of maturity. Three of the gases, Newport 8, Kernview and Newport 3 were quite simi- lar ranging in value from 0.39 to 0.56. Karales 2 was distinct from III-19 -34- the others with a value of 1.56. The second ratio calculated was propane:ethane, a wetness measure. Karales 2 has the lowest value, 0.04, and Newport 8 the high- est value, 2.62. Newport 3 at 0.91 and Kernview at 0.47 fall in be- tween. The spread of values is such that Karales 2 is different from Newport 8. Newport 3 and Kernview have intermediate values and can not be differentiated from the other two wells. None of the wells contained detectable amounts of ethylene or propylene except Karales 2 which had a small amount of propylene, pos- sibly a contaminant. This is normal because these gases are too reac- tive to exist for more than very short time periods. Besides hydrocarbon measurements, the CO2 and N2 contents of the well gases were measured. Karales 2 contained about 13% CO2' Nitrogen and 02 were present in their atmospheric ratio implying that they were present as contaminants, most likely due to leakage when the sample was collected. The sample collected from the Kernview well at Atlanta and Bushard also contained 13% CO2. After correcting for atmospheric contamination during collection using the 02 content, it was possible to calculate a value of 7% for the N2 content. Newport #3 also contained 14% CO2 and about 4% N2 after correcting for atmos- pheric leakage. Newport #8 differed from the others, containing 0.5% CO and 27% N measure- ments. and See Table 5 for all gasoline range results). III-20 -35- In order to further differentiate and characterize the well gases, stable carbon (delta 13C) isotopic measurements were made on the CH and CO2 of each well gas when possible. The Newport and Kern- view wells' CH were similar with carbon isotopes ranging from -54°/,0 to -58'/0,. The Karales 2 sample was heavier at -47°/,0. Only three wells contained sufficient CO2 to permit a reliable measurement. Karales 2 CO2 contained much heavier carbon (+20°/00) in comparison to Newport 3 and Kernview (+5.5°/0„ -3.5°/„). Karales 2 and Newport 8 may re- flect outlying values for well gas parameters while Newport 3 and Kern- view may reflect average values. Using this assumption, thermogenic gases, if they are a source of problems in Huntington Beach, fit the following description. The gases are probably dry (about 2% C2-C4) and accompanied by 10-15% CO2. Gasoline range components (C5-C8) are present with the volatiles. The ratio iso-b/n-b is about 0.5 and that of propane to ethane perhaps 0.7. Finally the delta 13C of the CH is -56°/00 or -57°/ao while delta 13C for the CO2 .is close to zero, either positive or negative. Of course, if gases seeping to the surface from reservoirs are to reflect these values, there can be little change caused by migration (see Table 6 for isotope measurements). Only one well, Weaver-Community 1, was sampled in the Sunset Beach Oil Field. It was very wet (65% CH4) with an iso-b/n-b value of 0.45. It had low (27) CO2 but the largest amount of N2, 57%, found in any of the wells after correcting for contamination based on 02 content. Its delta 13C for CH4 was -50.7'/00.. There was not enough Co to make a measurement. The Sunset Beach field produce:: oil wiLit III-21 -36- an API gravity of 30*. This field has some similarities with west Newport Beach but unfortunately data from only one well is available. However, the well is less than one -hundred feet from the problem area at 16642 Algonquin. Therefore, soil gases at this area, if they are thermogenic, have a high probability of being similar to those found in the sampled well. Following, the results of soil gas analyses from specific sites in Huntington Beach will be discussed and compared with the well analy- ses. Mr. Mel Wright, acting as consultant to the City of Huntington Beach and using the Roberti Report as a reference, selected 14 sites for resampling. These areas all exhibited anomalously high soil gas concentrations of methane approximately 10 months ago. Upon resam- pling, six sites no longer had high soil gas hydrocarbon concentrations but rather were typical of surface biological activity. These sites were located at the Oceancrest cul-de-sac, the Barados cul-de-sac, 21952 Harborbreeze, 9302 Southshore, 9131 Bermuda and the intersection of Cape May and Jonesport. At these sites methane was present in amounts ranging from 3 ppm v/v in the soil gas to 100 ppm v/v; values indicative of background to slightly above background. The unsaturates, ethylene and propylene, were present in amounts roughly equal to or greater than the corresponding saturates ethane and propane, a charac- teristic not observed with the well gases but typical of near surface bacterial activity. Also, the unsaturates were present in amounts as great as 7 to 10% of 'the methane present, again typical of biological activity and .different from the wells. Presently, these sites appear III-22 -37- to contain normal amounts of gases derived from biological activities. In the original study, only -the site on the Barbados cul-de- sac was classified as thermogenic, the others being biogenic. The large changes in the concentrations of the biogenic gases may be the result of variation in soil moisture content. If the moisture content is optimum, soil gas concentrations of hydrocarbons will be large and reflected in sampling results. At other times, concentrations will be much lower. These changes can occur on a scale measured in days. The reasons for the disappearance of the apparently thermogenic gas are not clear. Perhaps a changing water table forced A pocket of gas to the surface or closed off a migration pathway forcing a new path for moving gas. The original source of the gas is not known. The balance of the sites contained soil gases with high concen- trations of CH4, and other volatile hydrocarbons. In order to determine the origins of these gases, several analyses including hydrocarbon composition up to the gasoline range (C8 compounds), inorganic gas composition (CO2, 02 & N 2) and isotopic composition of the carbon in CH an CO2 were carried out. The analytical results from the sites, considered by themselves and in comparison with the well analyses, are most consistent with a biological origin for the gases. In considering the analytical results on the recovered gases, the most striking characteristic is the extreme dryness, in most cases, of the hydrocarbon fraction, a possible indicator of bacterial origin. III-23 -38- Five of the sites (Hagerstown cul-de-sac, intersection of Hamilton and Magnolia, 9511 Port Clyde, 9772 Kite and 16642 Algonquin) contained gases whose hydrocarbons were more than 99:9% CH4. At the three other sites (9611 Rockpoint, Karales 2 and the corner of Malibu and Banning) methane content varied from 99.0% to 96.7%. By comparison, the well gases were about 98% dry and in one case only 60% methane. Although the .difference from 98% to 99.9% does not appear large, it is unusual to find a thermogenic gas as dry, certainly within the Los Angeles Basin. The C 2+ fraction of the soil gases, when compared with the C 2+ fraction of the well gases, is further evidence of the dissimilarity between the two. All the soil gases,. except those recovered from the Algonquin and Kite sites, have the unsaturates ethylene and propylene present in amounts similar to propane and the butanes. In some cases, for example the sample taken at the Hagerstown cul-de-sac, ethane is present in amounts signifiantly greater than the other C 2+ components_ Similar situations have been encountered in gas samples recovered from sea floor sediments and are attributed to a small population of ethane producing bacteria. The presence of the unsaturates is indicative of a bacterial contribution to the soil gases. The samples taken from the Kite Street and Algonquin sites are different from the others because the unsaturates are missing. The Algonquin site is near abandoned wells and one producing well while the Kite Street site is within 50' of an abandoned well buried beneath the street. The composition of the gas from Weaver-Community I near III-24 -39- the Algonquin site is completely different from the .recovered soil gas being 35% wet while the soil gas is 99.9% dry. No sample of gas is available ,for the well at Kite but, by. comparison with other wells in the area, it should be at least 1-2% wet and not 99.9% dry as in the recovered soil sample. At the Algonquin site the ratio of propane to ethane is about 0.5 while the nearby well is just the inverse, about 2.0. The iso-butane to n-butane ratios are similar for the well and the site. The gas from. the Kite Street site has about 20 times as much ethane as propane and the iso-butane to n-butane ratio is about 0.4, similar to wells in the West Newport field. Gas samples from the sites with more than trace amounts of the butanes (Algonquin, Kite Street, Karales 2 and Hamilton at Magnolia) were analyzed for their gasoline range hydrocarbons, CS - C8' Only the Algonquin sample contained more than trace amounts. Again, the soil gases, with one exception, differ from the well gases. In addition to the hydrocarbon compositional tests, a second set of interrelated measurements was performed on the recovered soil gases. The nitrogen, oxygen and CO2 content of many of the recovered gases was measured as well the delta 13C of the carbon in methane and CO2. These tests are. useful in determining how biological processes have altered and/or contributed to the soil gases. The CO2 in soil gas is the result of respiratory activities while the 02 and N2 are carried into the soils dissolved in water. In the soil , N2 is mostly inert but 02 is consumed in metabolic . activities with the pass;1ge of III-25 -40- time. In normal soils without oxygen, bacteria may convert 'CO2 to very pure CH with a delta 13C of -65'/00 or less. If oxygen is present, different forms of bacteria will use it to oxidize methane to CO2. In this case the remaining methane will be heavier than -65'/0o and the CO2 delta 13C will approach that of the methane from the heavier side; i.e., it will start out at close to 0'/oo and get lighter. As the oxygen is consumed the ratio of N2 to 02 will increase from its atmospheric value of 4. It is not possible for isotopic data to confirm the biogenic origins .of the gases found at the intersection of Malibu and Banning and Karales 2 because not enough methane or CO2 was recoverd to make reliable isotopic measurements. The remaining wells fall into two - classes based on the stable carbon isotope ratios of their methane: those that are heavy, -25'/oo to -30'/00, and those that are light, -59'/00. The sites at the Hagerstown cul-de-sac, on Port Clyde and on Kite Street are all about -59'/00, lighter than any of the methanes from the wells. There has been consumption of oxygen based on the. N2/02 ratios which are 5 and 6 at the Kite and Hagerstown sites and 20 at the Port Clyde site. The CO2 concentrations vary directly with the oxygen consumption. At two of the sites (Kite Street and Port Clyde) sufficient CO2 was recovered to determine reliably that the CO2 was -50'/00. These facts are consistent with bacterial consumption of methane which was originally a few to several per mil lighter than III-26 -41- Stable carbon isotope ratios of -65*/00 or lighter for methpne are con- sidered diagnostic of bacterial origin. This confirms the origin decided for the Port Clyde and Hagerstown sites based- on their hydrocarbon compo- sition. For the Kite Street site, it is decisive for a bacterial origin. The sites at Rockport and the intersection of Hamilton and Mag- nolia contained methane that was very similar isotopically, both contain- ing carbon with a delta 13C value of about -25'/0,. The CO2 recovered_ at the same sites was also similar having a delta 13C of about -24°/00, very nearly the same as that of the methane. Buried organic matter subjected to high temperatures (>120'C) will produce methane as dry and as heavy as observed here. However, the Los Angeles Basin has a low temperature gradient (35°C/km) and is considered coal basin. Also, known production is from 8,000 feet or shallower implying tempera- tures of less_ f-La-n. .100°C. If oxygen depletion and CO2 concentrations are considered, both these sites are similar to the Port Clyde, Kite Street and Hagerstown cul-de-sac sites previously discussed. At those sites bacterial oxida- tion had made the methane perhaps 5'/0o heavier. If a similar effect has occurred at the current sites, then the methane source for these sites is near -30°/,,. If the source is non-biogenic, it must be quite hot, geologically unlikely in the Los Angeles Basin. Biogenic methane is derived from anaerobic bacteria which convert CO2 to methane. In such disparate environments as swamps and the rumen III-27 -42- of cattle, the resultant methane is usually 35`/oa lighter than the. CO2 source. Huntington Beach, in the areas these samples were recovered from, is built over a low lying marine flood plain. Consequently, most of the carbon dioxide in soils deeper than 10 feet is derived from marine carbonate which contains carbon of about 0V0,. Bacterial methane from ! such a source would be quite dry, as observed, and have an isotopic value of -30°/oo to -35°/00. Near the surface, oxygenated waters pro- vide a means for aerobic bacteria to utilize the methane for a food source, enriching the remaining methane to -25°/0, and producing CO2 with a similar isotope ratio. Finally, the Algonquin site must be considered. It is a special case because it is surrounded by several abandoned wells and has a pro- ducing well within 200 feet of .it. The gas recovered at the site con- tains no unsaturates and is the only soil gas to contain more than trace amounts of C5 to C8, or ' gasoline range, hydrocarbons. These facts, while not conclusive, are indicative of an oil related source. However, the extreme dryness of the soil gas (99.9% methane) in comparison to the wells (65% methane) and the relative heaviness of the soil methane (-310/„ vs -510/00) imply unrelated sources. Additionally, the CO2 in the soil gas is much heavier at -9°/,o than found at other sites and the oxygen is severely depleted (N2/02=26). Besides these differences, there is one other dissimilarity. 'The sampling site is in the middle of a large area that has almost no open space because everything is covered with asplia l t. or concrete_ This III-28 -43- explains the extreme oxygen depletion since there is no opportunity for water to carry dissolved oxygen into the soil. The CO2 delta 13C value is close to marine values because aerobic bacteria are inactive. The heavy methane (-31`/00) . has not been altered by bacterial oxidation. Although it is not certain, the unsaturates are absent be- cause the gases have been trapped long enough for them to react or their formation is in some way dependent on aerobic bacteria. Finally the gasoline range components may be present because the trapped methane has not been able to sweep them away as they are given off by the as- phalt. Alternatively, with several wells in the area, it is quite like- ly that spills may have occurred which are still giving off trace amounts of gasoline- range hydrocarbons. III-29 -44- CITY OF HUNTINGTON BEACH CONCLUSIONS AND RECOMMENDATIONS Areas within Huntington Beach- that are subject to hazardous or even dangerous accumulations of methane in their soil gases have been studied to determine the origins of the hazard causing gases. There are two possibilities for the origin of the soil gas methane which is responsible for all the problems. Either the methane is related to the West Newport Field and Sunset Beach Field oil production activities or to natural near surface production of methane by bacteria. In order to decide between these two choices, samples of the soil gases in problem areas chosen by Mr. Mel Wright, a consultant to the City of Huntington Beach, were recovered. In addition, histories of the oil fields were examined as well as general characteristics of the oil province known as the Los Angeles Basin which contains both fields. Based on comprehensive chemical evalution of the samples and information concerning the oil fields, we conclude that the soil gases we examined are biogenic in origin. The evidence to support this con- clusion is as follows. The gases are all dry, another characteristic of biogenic gas. Thermogenic gas can also be dry but the temperatures present in these fields are not high enough to have produced such gases. In addition, most of the gases are much drier than any of the wells sampled, a further indication of different origin. Unsaturated hydro- carbons are prevalent and are found in biogenic , not thermogenic, gases. According to the soils encountered in sampling, Huntington Beach III-30 i i -45- i is underlain by wet clays derived from old river flood plains and salt marshes. Such soils are a good source of biogenic methane colloquially known as swamp gas which normally is lighter than -60.0 to -65.0 All the methane samples have been oxidized somewhat judging by the depletion of oxygen in many gas samples. Accordingly, the sites at the Hagerstown cul-de-sac, on Port Clyde Street and on Kite Street -all have normal biogenic sources in shallow surface soils. The three sites containing heavier methane (Algonquin, Rockport Street, and the intersection of Hamilton and Magnolia) are also biogenic but using CO2 whose source is primarily marine. Although the soil gases are not related to oil production, it is probable that in at least two cases the gases are using well casings as conduits. One such location is in the middle of Kite Street and the second is underneath an apartment building on Algonquin. To miti- gate the problem on Kite Street, we recommend that shallow gravel filled trenches be placed beneath the street with perforated PVC pipe running through them. The pipes would all go to a street light pole and then be vented perhaps 25 feet above street level. The Algonquin problem is more severe because a building is involved. Areas not covered by the buildings are cemented for parking. Probably some of the cement will have to be cut out and a venting system similar to the one de- scribed above installed. The cement will have to be relaid over the trench lines. If there are enclosed areas within the buildings that do not have good air circulation methane monitors and a fan ventil- ation system must be installed to guard against an explosive build-up of III-31 -46- gas. Other areas within Huntington Beach that have soil gas problems with close association with a well and that feel threatened should determine the areal extent of the problem. If it is small, perhaps nothing should be done except to be sure that closed spaces are occa- sionally vented. If the area is larger and/or appears to extend beneath a building or residence, a simple perforated PVC pipe in gravel trench . system is a cost effective way to mitigate the problem. Ventilation or methane gas monitors should also be considered. In areas of new construction soil surveys should be performed to detect abnormal soil gas concentrations. Building permits should not be issued allowing construction over abandoned wells even if there is no detected leak at the current time.

The tip of the probe is a screw-on chisel point which con- ceals a side port connected to the hollow center (see Fig. 1). The small bore size minimizes the atmospheric air contamination in the soil gas sample. To recover a soil gas sample, the probe is ' driven to a nominal depth of three (3) feet in the soil using a slide hammer. At depth,- a gas tight syringe is used to remove air from the probe's hollow center and the probe rotated twice to expose the side port to soil gases. The soil gases are removed by syringe for analysis of their hydrocarbon content (see Fig. 2 for a typical chromatogram) using FID chromatographs. As little as 10 ppb vol/vol of hydrocarbon can be detected. The advantages of the soil probe method are its rapidity, ability to access areas not possible with a drill truck, and little or no damage to the environment.

III-40 -55- APPENDIX II CANNED HEADSPACE: Cl--C, HYDROCARBON GASES In the canned headspace method, 300 - 400 cc of sediment is col- lected from the bottom of an augered hole by removing the auger and taking the sediment sample directly from the auger blade. The sediment is immediately canned with 200 cc of water in a No. 212 can (860 cc vol- ume). .The lid is equipped with a silicon septum. In the laboratory, each can is shaken for five (5) minutes on a Harbil agitator to homogenize the sample and bring all hydrocarbons into equilibrium with the headspace gas (250 cc). An aliquot of the headspace gas is withdrawn for analysis by FID chromatography. The data are reported as volume of hydrocarbon gas per volume headspace gas. The limit of detection is 10 ppb for the hydrocarbon analysis. Thus the canned samples serve not only as confirmation of the probe results but also as a reservoir of gas for additional tests such as isotopic analyses in cases where it is necessary. The canned samples also provide information about the vertical extent of anomalies. Although the methane measurements are of primary importance, quantitation of the heavier hydrocarbons is necessary with respect to determining the origin of the methane in anomalies, since this informa- tion has a direct bearing on mitigation procedures. Once the hydrocarbon III-41 -56- gas composition is known from the field analysis of a gas probe sample or confirmed with analysis of the canned sample headspace, it is pos- sible to make a reliable decision regarding the source utilizing criter- ia established by the oil industry and organic geochemists. Although unusual situations may be encountered, certain guidelines are reliable. If the soil gas contains methane accompanied with unsaturates (ethylene and propylene) present in amounts comparable to the corresponding sat- urates (ethane and propane), the gas is bacterial in origin. In some cases, the methane can be very dry (less than 1% C 2+) constituting more than 99% of the hydrocarbon gas. If the unsaturates are missing or present in only minor amounts and the C 2+ gases constitute up to 20 or 30% of the hydrocarbon gases, the origin is petroleum related. If hydrocarbon gases are the result of thermal processes, the unsaturates are missing and methane constitutes 97% - 98% of the hydrocarbon frac- tion. Besides the chemical composition of the hydrocarbons, the stable carbon isotopic compositon of the carbon in the methane can be measured and this information combined with the compositional information to decide the hydrocarbon gas origin. Methane containing carbon with an isotopic ratio of less than -60*/0o to -65*/,o is biogenic, while methane with an isotopic ratio greater than -55'/,a but less than -40°/0, is petroleum related. Methane with carbon measuring -40°/oa or greater is derived from thermal processes. III-42 -57- REFERENCES Allen, D.R. and Hazenbush, G.C. (1957); Sunset Beach Oil Field: Calif.

III-43 BUILDING OVER OIL WELLS With 3,816 wells having been drilled in Huntington Beach over the last 50 years, develop- ment of properties on, over or in the proximity of producing, idle or abandoned wells occurs with increasing frequency. The State of California, Division of Oil and Gas, does not recommend the building of a structure over any abandoned oil well. This policy stand by the Division of Oil and Gas would make large parcels of land within the City undevelopable. It had been the policy of the City in the past to allow construc- tion over abandoned oil wells. With the recent problems associated with methane gas, and the Divisions policy about building over wells,.a new approach from both the safety and liability points had to be adopted. Through the City Oil Code the following ordinance was adopted in 1981 and amended in 1987: 15.32.120 Abandonment requirements prior to new construction. All abandoned or deserted wells or drill sites shall meet the most current abandonment requirements of the Division of Oil and Gas prior to the issuance of any building . or grading permit for development of the property. New structures shall not be constructed directly over abandoned wells unless due to configuration of the property it is necessary. If it can be proved to be safe and this is no other alternative, it may allowed if procedures set forth by the Fire Chief are followed. This ordinance did two things: 1) It allows the City to require owners of properties who wished to develop said properties to bring their wells up to the most recent abandonment standards, as required by the Division of Oil and Gas. With time and through redevelop- ment those older wells built over some years ago will be brought up to a much safer standard, 2) It gives the Fire Chief the authority to require and set standards. If proven to him by experts within the petroleum field, that construction over abandoned wells can be done in a manner as not to endanger life or property it will be allowed. Each situation is examined on a case by case bases with advanced inspections and reporting required, methane venting systems and in some cases permanent monitoring devices required. Attached is the Huntington Beach Fire Department procedure and guidelines for building over abandoned oil wells as set forth by the Fire Chief. 7008f (Revised 10/28/87) IV-1 CITY OF HUNTINGTON BEACH OIL AND GAS WELL REVIEW PROCEDURE Name of Applicant Address of Applicant Date Plan Check Number Plan Checker's Name Signature Phone Number A review of State Division of Oil and Gas maps indicated that your proposed construction site located at lies within the boundaries of (Oil Field/County) There is/are (number) active, idle, or abandoned wells(s) located on or adjacent to the site; therefore, before a building permit can be issued, it is necessary to obtain a site-plan review from the State Division of Oil and Gas. The Division of Oil and Gas will determine if affected wells have been abandoned to current standards. Wells not abandoned to current standards, may require abandonment/reabandonment. THE STATE DIVISION OF OIL AND GAS RECOMMENDS THAT A DILIGENT EFFORT BE MADE TO AVOID BUILDING OVER OR IN THE PROXIMITY OF ANY WELL. I. SITE REVIEW PROCEDURES TO BE FOLLOWED BY PROJECT APPLICANT. A. Contact the Division at: Division of Oil and Gas 245 West Broadway, Suite 475 Long Beach, California 90802 213-590-5309 B. Provide the following information: 1. Area Location 2. Oil Field/County 3. Company/Operator 4. Well Designation 5. Major Cross Street (or other identifier) C. The applicant must submit the above well information to the Division of Oil and Gas office. The Division of Oil and Gas engineers will review the data and provide the applicant with the well location information. D. Using the well locations provided by the Division of Oil and Gas, uncover the well(s) and have the well location(s) surveyed by a licensed surveyor. If any well cannot be located using the original description of record, a diligent effort, including excavation, must be made to locate it. Some surface indications that may help in locating wells are metal detector responses, the presence of well cellars, oil field debris, and oil-saturated earth. 1099F (10187) IV-2 Plot the location of each well .on the site plan. The well survey description must reference a point on the site plan which, in turn, must reference a point on an existing Division map if a common point is not available. Identify each well with the name of the company/operator and well designation. Submit three (3) copies of the final site plan and three (3) copies of each well location survey to the Huntington Beach Fire Department for verification of the plotted well locations. Following well location verification, the Huntington Beach Fire Department will forward them to the Division of Oil and Gas for site evaluation. The site plan should indicate the property boundaries, an area of at least twenty-five (25) feet outward from the perimeter of the property, any proposed or existing structures, and any existing or proposed roads or streets that pass through or are immediately adjacent to the property. The site plan should also include a plot (to scale) of all existing and proposed oil field facilities (tanks, processing equipment, enclosures, pipelines, etc.) that will be operating on the site after completion of the proposed development. You must also include a description of the existing type and height of all oil field enclosures and list any facility modifications that are part of the development plans. E. The following procedures are to be used to locate site plan wells and to verify that an adequate search was completed: Step 1. The developer/landowner shall survey the well locations using the "Location of Record" and dig a hole that is at least fifteen (15) feet long, fifteen (15) feet wide, and twelve (12) feet deep, if necessary. If any indications of an oil well are observed upon completion of the excavation, or if there is any information available that original conditions have changed since the well was drilled, a larger hole may be required. Step 2. If the well is not located using procedures listed in Step 1, a metal detector should be used to survey the area (inside and outside the excavation). All safety precautions must be observed while working inside the excavation site. If it is unsafe to enter the excavation, the -metal detector can be lowered by means of a rope and/or extension device. Step 3. The developer/landowner shall excavate all indicated metal detector locations by digging a hole that is at least ten (10) feet long, ten (10) feet wide, and twelve (12) feet deep, if necessary. If any indications of an oil well are observed upon completion of the excavation, or if there is any information available that the original conditions have changed since the well was drilled, a larger hole may be required. Step 4. The developer/landowner shall notify the Division of Oil and Gas to witness all completed excavations before they are refilled. Pictures shall be taken of all excavations and each picture labeled appropriately. A Division of Oil and Gas Engineer should also review the well survey. Step 5. If the well search efforts proved unsucessful, the Division of Oil and Gas representative and the developer shall prepare a 1099F (10/87) IV-3 brief written report describing the search procedures and attach the excavation pictures. F. A Division of Oil and Gas Engineer will review the submitted plans to determine what well work is required. The Division of Oil and. Gas Engineer will prepare Form OG 190, which will indicate the wells that need to be abandoned or reabandoned before a building permit can be issued. Form OG190 will also include requirements and recommendations regarding any active well facilities that will remain after the development is completed. When the review is complete, the reviewing Engineer will affix the Division of Oil and Gas certification stamp to the three (3) copies of the site plans and three (3) copies of Form OG 190. Two (2) copies (along with two (2) copies of the well location surveys) will be returned to the Huntington Beach Fire Department, which will then forward one (1) copy to the applicant. The remaining copy will be retained by the Division's district office. II. ABANDONMENT PERMIT PROCESS. A. Before any well operations are commenced, an application to abandon or reabandon each well must be filed with the Division of Oil and Gas (Form OG 108 or OG 123). This application must outline the work proposed to upgrade the well to current requirements. B. The Division will respond with a permit (Form OG111) that sets forth the conditions and requirements to be met. C. A well abandonment contractor may be retained by the applicant to do the required abandonment work. D. The Fire Department must witness welding of the top plate. E. When the well work is complete and all records received, the Report of Operations (Form OGl09) and the Report of Well Abandonment or Reabandonment (Form OG 159) will be issued. A copy of each will be sent to the Fire Department and the applicant. NOTE: IF, DURING THE CONSTRUCTION PROCESS, ANY PREVIOUSLY UNKNOWN WELL IS DISCOVERED, THE DIVISION OF OIL AND GAS MUST BE NOTIFIED IMMEDIATELY SO ABANDONMENT REQUIREMENTS CAN BE DETERMINED. III. PRIOR TO RELEASE OF BUILDING PERMITS. The base principle is that no buildings should be built over abandoned oil wells. If it can be proven to be safe and there is no other alternative, the following criteria must be met: Analysis of well by a State of California registered Petroleum Geologist or Petroleum Engineer. (These may be obtained in the Pacific Coast Oil Directory, or Personnel Directory of California Oil and Gas Producers.) 1099F (10/87) IV-4 Protection Designs (if needed) Vapor venting systems Methane detection Etc. Well abandonment to current Division of Oil and Gas (DOG) Standards. Review by the City of Huntington-Beach. Proven well with integrity. Property owner responsible for correcting all future problems. Title disclosure to future property owner and their responsibilities. Filing cost of $244. IV. GUIDE FOR CONTENT OF ABANDONED WELL DISPOSITION REPORT. A. Well History - When drilled, when abandoned. Special shooting or recompletion work. Production oil and gas at, or last reported, prior to abandonment. B. Casing and Liner - Types and depths, pipe grades. Submit copies of DOG Well History form. C. Cement - Location and amounts; completion and abandonment. Submit copies of DOG Abandonment form and pertinent well cementing data. D. Zonal Depths - List oil and/or gas show depths. E. Copy of Electric Log and/or Core Data and/or ditch or sidewell sample description and/or Drillers Log. F. Diagram of well showing casing, cement, and zones roughly to scale. G. Gas - Leaking at beginning, during, or after work on well. Report change. What is analysis of gas (Cl, C2, C3, C4, C5, etc.), approximate .flow, heavy, medium, light? H. Issues and types of recommendations that must be made by preparer: 1. Reabandon; must reabandon if not to present DOG Code. 2. Design vented recovery system; must use if well is to be built over. 3. Install permanent detector and alarm system. 4. Don't built over. 5. Don't build near. 6. Okay to build near, or over, stipulate why. 7. High gas flow needs flare installed. 8. Overall safety of well. This guide is to be considered a minimum. 1099F (10187) IV-5 BONDS With the past fall in .oil prices and the decrease in production for many of the smaller producers, more and more oil wells are being shut down. At present, the City requires through Ordinance Corporate Surety Bonds in the amount of ten thousand dollars ($10,000) per well; or in lieu of filing a separate bond on each well, owners may file a Blanket Bond in the amount of fifty thousand dollars ($50,000) if more than five (5) well are owned. With the cost of abandonments and site clean up costing on an average of forty thousand dollars ($40,000), and capable of running as high as one hundred thousand dollars ($100,000) the City is now in an unprotected position should any operator default on his well. It is recommended that the Oil Code Bonds be increased to fifty thousand dollars ($50,000) per well; or in lieu of filing a separate bond on each well, owners may file a Blanket Bond in the amount of two hundred and fifty thousand dollars ($250,000) if more than five (5) wells are owned. If the well owner and property owner are one in the same, provisions could be made to have the property pledged in lieu of bonds. Attached is a copy of the current bond ordinance from the Huntington Beach Oil Code. 7008f (10/87) V-1 15.16.010--15.16.040 Chapter 15.16 BONDS Sections- 15. 16.010' Existing wells--Exception for present bonds. 15.16.020 New wells--Bond required. 15.16.030 Bond form. 15.16.040 Single bonds. 15.16.050 Substitutions. 15.16.060.

(Ord.. 2491, 1 Jul 81) 15.16 .050 Substitution. A substitute bond may be filed in lieu .of the bond on file hereunder and the department shall accept and file same if it is qualified in proper form. and substance. The bond for which it is substituting shall then be exonerated. (Ord. 2491, 1 Jul 81) 15.16.060 Blanket bonds. Any operator, in lieu of filing a separate bond on each well as required by the foregoing, may file a blanket bond .in the amount of fifty thousand. dollars ($50,000) if he has more than five ( 5) wells. (Ord. 2491, 1 Jul 81) 15 .16 .070 Default in -performance of conditions--Notice to be given. Whenever the department finds that a default has occurred in the performance of any requirement or condition of these regulations, a written notice thereof shall be given to* the principal and to the surety on the bond. Such notice shall specify the work to be done, the estimated cost thereof and the period of time deemed by the department to be reasonably necessary for the completion of such work . After receipt ' of such notice, the surety shall, within the. time therein specified, either cause or require the work to be performed, or failing thereupon, shall pay over to the department 125 percent of the estimated cost of doing the work as set forth in the V-3 ' 15.16 .080 notice. Upon receipt of such monies, the department shall proceed by such mode as deemed convenient to cause the required work to be performed and completed, but no liability shall be incurred therein other than for the expenditure of said sum in hand. In the event that the well has not been properly abandoned under the regulations of the division of oil and gas, such additional money may be demanded from the surety as is necessary to restore the drill site in conformity with the regulations of this title. In the event the surety does not cause the work to be performed and fails or refuses to pay over to the department the estimated cost of the work to be done as set forth in the notice,/ the city may proceed to obtain compliance and abate the default by way of civil action against the surety., or by criminal action against the principal, or by both such methods. (Ord. 2491, . 1 Jul 81) 15.16 .080 Exoneration. When the well or wells, covered by said bonds have been properly abandoned in conformity with all regulations of this title, and in conformity with all regulations of the division of oil and gas and notice to that- effect has been received by the department, or upon receipt of a satisfactory substitute bond, the bond issued in compliance with these regulations shall be terminated and cancelled and the surety relieved of all obligations thereunder . (Ord. 2491, 1 Jul 81) V-4 PREDICTING FUTURE OIL OPERATIONS The City faces important decisions regarding land use as the oil in the field continues to .be depleted and pressure increases to abandon parts of the field and to redevelop the surface. Fiscal impacts are important factors in determining the best use of the land and the City's policy toward continue oil operations. The lack of available open space in this area and the growing housing shortage create pressure to abandon oil fields and to redevelop them for housing. At the same time, rising oil prices and the relaxation of price controls on domestic oil make continued oil production, even at low levels, increasingly attractive. Higher prices may also make more expensive production techniques (such as water injection) profitable in parts of the field where they have not yet been applied. Further, while production in the Huntington Beach field has been declining, new technologies are being tested here which might rejuvenate the field. In light of these changing variables and different possibilities, several "scenarios" of oil operations over the next decade have been analyzed. The first assumes, overall, that the number of wells, acreage and production levels remain relatively unchanged. This could come about if the decline of production in some parts of the field are balanced by new waterflood projects and other enhanced recovery program. Production among small independents is assumed to continue dropping, but the "recycling" of their parcels to new uses would proceed very slowly, largely due to the increasing price of oil. Thus, the number of wells, acreage, and overall oil production would remain relatively constant for the next ten years. The second scenario envisions a gradual phase-out of oil operations in the Townlot and Downtown during the late 19801s, but operations elsewhere in the City will continue relatively unchanged. This is theorized, because the Townlot and Downtown areas are especially valuable part of the City, and pressures for redevelopment there will be stronger than elsewhere. The third scenario sees a phase-out of the small-scale independent operations during the next decade, while the major oil compancies continue operating near their present levels. In many way, this scenario may best approximate what will actually happen. Discussions with the major oil companies in Huntington Beach indicate that they expect to continue operating at least another 20 years and that the technologies may not dramatically increase production, but will offset recent declines and keep production levels up for several years. At the same time, the production of the independents has continue to decline. Generally speaking, they cannot apply. the enhanced recovery technologies available to the larger companies. As their,production drops and the value of the surface for housing continues to rise, these parcels would gradually recycle. The last scenario considers the possibility that, rather than abandoning their operations, the small independent oil companies along with one or more of the majors, join together and form a "unit." By combining the resources of all the participants, the unit has the capital and the surface acreage to apply waterflood and other enhanced recovery techniques. Thus, production increases and the operations continue throughout the 19801s. 7008f (10/87) VI-1 HUNTINGTON BEACH OIL FIELD CONSOLIDATION PLAN At the end of 1985, the Huntington Beach Oil Field contained approximately 1,944 wells. Of those, 992 were active and 952 shut-in. The active wells produced on average nearly 22,000 barrels of oil per day (BOPD)during 1985. On an arbitrary basis of size (as measured by number of wells) the sixty-six operators in the Huntington Beach Oil Field can be segregated into three groups. Those groups which might be referred "to as majors," "independents" and "small operators." Exhibit A which lists these operators by group indicates the well status as of December 31, 1985 and results of full year 1985 operations. The following chart indicates the relative size of each group on a percentage basis. # in Group % Wells % Active % Idle %BOPD % Gas Majors 3 84.0 72.1 96.4 95.0 93.0 Independents 10 9.2 17.2 0.9 3.1 3. Small Operators 53 6.8 10.7 2.7 1.9 3.2 TOTALS 66 100% 100% 100% 100% 100% The above table highlights the fact that the three largest producers in the field, Shell, Chevron and Union Oil produce most (95.0%) of the oil. Conversely the remaining 63 producers with 16.0% of the oil wells produce only 5.0% of the oil. Even more dramatic, however, is that the 53 "Small Operators" as a group only produce 1.9 percent of the oil. It is generally acknowledged that the larger operators are better prepared to meet the operating requirements imposed upon them by the City's Oil Code, the California Division of Oil and Gas (DOG) and environmental agencies such as the South Coast Air Quality Management District, the Regional Water Quality Control Board and others. The transfer of the areas operated by the "Small Operators" to operators of larger size should be an important objective in the City's regulatory scheme for the field. The Coastal Energy Impact Program produced by the City of Huntington Beach in February 1980, contained recommendations for policies and actions to be included in the City's Local Coastal Plan. At Part E.3.2 policy recommendations were made with regard to "Unitization and Consolidation and Siting Priorities." The following is the text of those policy recommendations: "Unitization and consolidation help to reduce the amount of land use for oil activities, which is a more efficient use of this valuable coastal resource. Policy III-2-a: Encourage unitization and consolidation when such activities 1) reduce the area used for oil facilities, 2) are not more environmentally disruptive than existing arrangements and 3) do not jeopardize public health, safety or welfare. 7008f (10/87) VI-2 The following sitting priority requires consolidation of new oil facilities either in existing islands or on other oil parcels, where possible. This practice concentrates the adverse impacts of oil facilities which tends to make mitigation strategies easier and less expensive. Where consolidation or clustering is infeasible, new sites outside the coastal zone are generally preferred over new sites within the coastal zone. This reflects the special value of the coastal zone for other competing uses. In all cases, environmental impacts, public safety and welfare, and aesthetic considerations must be taken into account in choosing the site for new facilities. Policy III-20-b: Adopt the following priority for siting new oil-related facilities, provided that in each case a) the new activities are adequately screened and buffered from surrounding uses, b) adverse environmental impacts are mitigated to the maximum extend feasible, c) the activities do not jeopardize public health, safety or welfare, d) there is no other feasible location which is less disruptive: 1. existing consolidated islands (including the entire Aminoil lease) 2. new consolidated islands 3. existing oil parcels 4. new parcels outside the coastal zone 5. new parcels within the coastal zone The mechanism at hand for such an amalgamation of the interests held by the "Small Operators" is unitization. Unitization allows the combination of a sufficiently large area to justify the use of enhanced oil recovery methods which changes the overall character of the reservoir performance (oil recovery rate) and therefore, economics of the project area. There are three major unitization (or consolidation) projects, at present, under various stages of assembly within the Huntington Beach Oil Field. These three projects, the Townlot Area, the Springfield Area and the North Flank Area, encompass essentially all of the onshore portion of the oil field not otherwise controlled by either Chevron or Shell (in the Bolsa Chica). These three areas are shown o_n Exhibit B, the map of the Huntington Beach Master Plan - Oil Well Consolidation. At present each of these unit areas can be characterized by the following table: Est. Current Size Number of Production Area (Acres) Existing Wells (BOPD) Townlot 315 166 400 Springfield 140 41 150 North Flank 640 201 400 TOTAL 1,095 408 950 7008f (Revised 10/28/87) VI-3 The installation of unitized consolidated oil projects in each of the three project areas would significantly increase oil production from fewer wells. It would also dramatically reduce the acres impacted by oil operations. While actual operating history will be required to ascertain the accuracy of the estimates, initial estimates for each of the consolidated projects are as follows: New Potential Est. Peak Consolidated Wells Ultimate Production Area Drill Sites Required Recovery Rate (BOPD) Townlot 4 or 5 70 30 M Bb1s 7,500 Springfield 1 45 10 M Bbls 2,500 North Flank 3 or 4 100 20 M Bbls 5,000 TOTAL 8 to 10 215 60 M Bb1s 15,000 The full implementation of oil well consolidation in each of the three project areas would incrementally add 14,000 BOPD to the field's daily production level. While that would be a very significant 64 percent of current production level, it will represent a much larger percentage addition as the daily production rate from the offshore and other onshore portions of the field continue to decline. Such additional production suggest a stabilization of the overall oil production rate in the City which would result in a stabilization of City revenues from oil production. This additional oil will be produced from significantly fewer wells. For the three project areas taken together, total wells are reduced by nearly 50 percent. More importantly, the 215 required wells would be centralized in 8 to 10 consolidated drillsites. The total number of operators in the field would drop from 66 to around 10. In addition to the three majors and 3 consolidated project operators, there would only be a few other operators with a limited number of wells not otherwise consolidated/ A greatly reduced number of operators would make administration of the City's Oil Code simpler and more effective. Importantly the consolidated project operators would not only have the financial strength to meet Code requirements, but also to respond more effectively and appropriately to any chronic or emergency problem, such as pipeline leaks in City streets or methane leaks. At present, City code enforcement officers have a problem of determining the responsible party for such problems. Under a full field consolidation scenario, each large project area operator would assume broad responsibility for such general problems in their area. 7008f (10/87) VI-4 4I 1 Llt�l ,%tW I-_ A k � OIFlii 1 •lf--trj'� S�NY g �Y k� eravrec� re alEv M.
