Johnston Commissioner Robert N. Christenson, P.E., Commissioner Chairman of Commission Cammy Oechsli Commissioner 1998 ANNUAL REPORT State of Alaska Alaska Oil & Gas Conservation Commission 1998 Annual Report INTRODUCTION This document characterizes historical petroleum industry activity in the State of Alaska with special reference to operations undertaken in 1998. A variety of information and analyses related to Alaskan petroleum industry production and exploration operations are compiled by the Commission, a portion of which are presented here. Responding to public requests for related information is a priority for Commission staff. Alaska's total liquid hydrocarbon production (oil and natural gas liquids) in 1998 was 463 million barrels, for an average rate of 1.27 million barrels per day, a 9.0% decline from 1997. This rate of decline is a 29% increase over last year's 7.0% rate. Oil production accounted for approximately 429 million barrels, and natural gas liquids approximately 34 million barrels. Total dry and casinghead gas produced was nearly 3.4 trillion cubic feet, a volume approximately equal to last year's total. Approximately 2.92 trillion cubic feet of casinghead gas was reinjected to support enhanced oil recovery operations, a volume that is also roughly equivalent to last year's volume. Of the approximately 480 billion cubic feet of net gas produced, 227 billion cubic feet was used to fuel oil and gas operations, 8 billion cubic feet was flared, and 226 billion cubic feet was sold. Water injection for enhanced oil recovery totaled nearly 931 million barrels or nearly 2.6 million barrels per day. A total of 751 water and gas injection wells were active statewide. Exploratory drilling activity consisted of 12 wildcats on the North Slope and 2 in the Cook Inlet basin. Total exploratory footage drilled for the state was over 119,465 feet. Development and service wells drilled on the North Slope in 1998 totaled 128 and 7 for the Cook Inlet basin. Total development and service well footage drilled in the state was over 2.1 million feet. There were 3,461 active wells in the state including 148 gas development wells, 2,223 oil development wells and 902 service wells. The Badami Pool began production in August 1998 and the operator received approval from the AOGCC for enhanced recovery operations and to import dry gas from Duck Island Unit. Badami wells produced at marginally economic rates through the end of 1998. New and expanding North Slope development projects include Tarn, Tabasco, and West Sak Pools in the Kuparuk River Unit, Sambuca, Midnight Sun, and West Beach Pools in the Prudhoe Bay Unit, the Eider Pool in Duck Island Unit and the Alpine Pool in the Colville River Unit. The facilities sharing agreement in Prudhoe Bay Unit and the interest alignment agreement in Kuparuk River Unit have made development of the sizable satellite accumulations in these units likely. Initial satellite development results are favorable but the current price environment has caused owners and operators to reevaluate the pace and amount of development over the next few years. In all cases drilling activity will be reduced until a more beneficial price environment prevails. Anadarko Petroleum Company acquired a large acreage position generally located a significant distance south and west from existing infrastructure on the North Slope. This importantly presages exploratory activity in plays other than those exploited to date adjacent to the Arctic Coast. Commercialization of North Slope gas continues to be evaluated by both the owners and the state. Significant Cook Inlet activity included the Arco and Anadarko gas discovery at Lone Creek. This new field discovery is currently being evaluated for commercial production. Gas Resources Inc. started Alaska's first coalbed methane development with the initiation of a three well pilot project in the Susitna Valley near Houston, Alaska. Cross Timbers Inc. purchased Shell's interest in the Middle Ground Shoal Field and intends to operate that property. Unocal and Forcenergy continued an exploration program in the Cook Inlet, which included the drilling of a wildcat well. Users of this report are invited to submit suggestions for its improvement. Con;; R~obe~ .~Christenson, P E Chairman Commissioner iii ALASKA OIL AND GAS CONSERVATION COMMISSION The Commission is an independent, quasi-judicial state agency. It is established under the Alaska Oil and Gas Conservation Act, Title 31 of the Alaska Statutes; its regulatory authority is outlined in Title 20, Chapter 25 of the Administrative Code. The Commission oversees oil and gas drilling, development and production, reservoir depletion and metering operations on all lands subject to the state's police powers. It acts to prohibit physical waste of crude oil and natural gas, ensure maximum ultimate recovery, and protect correlative rights of anyone owning oil and gas interest in lands subject to Alaska's police powers. It also administers the Underground Injection Program for oil and gas wells in Alaska by regulating underground disposal of drilling waste and injection operations for enhanced oil recovery. The Commission carries forth its statutory mandates consistent with the protection of health, safety and the environment. It strives for cooperation with industry, while maintaining well-defined and essential regulatory requirements. Budget cuts and expanded field development have reduced the Commission's ability to evaluate drilling and reservoir management practices and reduced inspection capability below minimum standards. The Alaska Oil and Gas Conservation Commission currently manages over 70 reservoirs and 3,400 active oil and gas wells. Fifteen years ago, we managed 41 reservoirs and 1,867 wells. Our budget then was $2.3 million with 26 employees; today it is $1.6 million with 19 employees. This contrast becomes significantly greater if adjusted for inflation. 35OO 3000 2500 2OOO 1500 1000 500 Alaska Oil and Gas Conservation Com rn ission N umber of Active W ells v.

BLOWOUT PREVENTION SYSTEMS (BOPS): Witness BOPE tests following installation on the surface casing on each exploratory well and on all wells which may encounter high pressure zones; also on each rig at start up or after major moves; and at not more than two month intervals for all drilling and work-over operations. RIG INSPECTIONS: Conduct inspections on all rigs on all wells as is necessary to ensure compliance with AOGCC regulations; these tests are to complement BOP tests, not replace them. SAFETY VALVE SYSTEMS (SVS): Witness at least 25% of those tests required by regulations or conservation order and 75% of all retests, rotated so that all wells are witnessed at least once every two years. Where safety valve systems are required by regulation, all pilots, surface, and subsurface safety valves are tested at six-month intervals. MECHANICAL INTEGRITY TESTS (MITs): Witness MITs on all new injection wells, converted producing wells, and after work-overs when the tubing and/or packer have been removed; and witness at least 25% of those tests required by regulation, conservation order, or other commission directive. WELL BORE CEMENT PLUGS: Witness at least one critical plug in each well during abandonment; e.g., across the intended production zone, across casing perforations, or the surface plug. Non-critical plugs include but are not limited to those for profile modification, well-bore kick-off, and casing stabilization. LOCATION CLEARANCE INSPECTIONS: Inspect all abandoned locations to ensure casings have been cut-off below ground level, are properly plugged, and are covered with a steel marker plate; to ensure that all junk and equipment have been removed; to ensure there are no open pits or depressions on the pad to pond water and that the pad has been graded. The Commission has waived inspection following site inspection and approval by other jurisdictional agencies; e.g., BLM or DNP,/DOL. METERING: Gas Meters: Inspect facilities and witness gas meter calibrations at major custody transfer facilities every six months and at minor ones once each year. Oil Meters: Inspect facilities and witness meter provings on oil meters at Prudhoe Bay every month, major I_ACTs every quarter, and topping plants every six months. NOTE: LACT stands for "lease automatic custody transfer~'. 1998 FIELD INSPECTION PERFORMANCE This is an analysis of the performance of the field inspection program for the 1998 Calendar Year compared to the stated goals in "Field Inspection Goals". DIVERTERS: Twenty-four (24) Diverter Tests were witnessed, of which 6 were on 9 of the remote Exploratory Wells, for a coverage of 67%. BLOWOUT PREVENTION SYSTEMS: Inspectors witnessed 155 BOP tests. Our goal was to witness at least one test on each rig every two months and on the surface casing of all exploratory wells. Inspectors witnessed 7 of 13 initial BOP test on exploratory wells. RIG INSPECTIONS: We conducted 97 RIG BOP System Inspections. SAFETY VALVE SYSTEMS: There are approximately 2,187 active oil and gas production and injection wells requiring safety valve inspections that were tested every 6 months. We witnessed 1,250 SVS inspection tests. WELL HOUSE INSPECTIONS: Inspectors conducted a total of 1,404 well head and well house system inspections on the North Slope and in Cook Inlet. MECHANICAL INTEGRITY TESTS: There were 864 enhanced recovery and 60 disposal wells at year-end; of these there were 38 new and 10 converted wells. MITs were witnessed on 36 of the 48 new and converted wells and on 152 of the existing wells. WELL BORE PLUGS: Five (5) remote Exploratory Wells were plugged and abandoned. We witnessed critical plugs in 3 of the 5 exploratory wells that were plugged. Thirteen (13) additional well bore plugs for abandonment were witnessed. LOCATION CLEARANCE: Seven (7) location clearance inspections were conducted. METERING: Gas Meters: We witnessed calibrations at 19 of the 23 scheduled facility inspections while witnessing 23 of the 29 scheduled meter calibrations. Oil Meters: We witnessed meter proving at 54 of the 59 scheduled facility inspections. Of the 147 meter provings scheduled, we witnessed 154 meter provings (including additional meters at PS-1 Prudhoe, Lisburne and Badami Field). The oil metering facilities at Pump Station 1 and Kuparuk account for 85% of the crude oil produced in the state in 1998. At these facilities, we witnessed the proving of 93 meters.

Due to injuries, we had only one inspector for two months ..... Effectively 4 inspectors in-the-field due to resignation, reassignment, and leave for family illness. ...... Five Inspectors 3 Months, Four Inspectors for 6 months, 3 Inspectors for 3 Months. Gas Disposition Although flaring was generally down statewide, increases were caused by Badami Field startup on the North Slope and repairs and equipment upgrades in the McArthur River Field of Cook Inlet. Total gas flared or vented in 1998 was 7.9 billion cubic feet (bcf), down 5% from the 1997 total of 8.3 bcf and up 11% from the 1996 total of 7.1 bcf. This was also an 11% decrease from the 1995 total of 8.8 bcf. Of the 7.9 bcf flared in 1998, 3.7 bcf (46.8%) were pilot and purge volumes. Pilot gas is defined as the gas routed to a safety flare system to maintain an ignition source. Purge gas is used to maintain forward flow and a positive pressure in the safety flare system. Of the remaining gas vented or flared, 2.0 bcf (25.3%) was flared in events under I hour in duration, and 2.2 bcf (27.8%) was flared in events which lasted over 1 hour in duration. Investigations conducted in 1995 and 1997 resulted in 35,725 mcf and 11,000 mcf declared waste, respectively. No investigations during 1996 resulted in declarations of waste. Investigations are continuing for several 1998 flaring events. Arctic Slope North Slope operations contributed 5.8 bcf (73.4%) to the total volume vented and flared for 1998. Of this, 1.5 bcf was flared in events over 1 hour in duration. This constitutes a 21% decrease from the 1997 volume (1.9 bcf) flared in events over 1 hour in duration. Cook Inlet Basin Cook Inlet operations made up the remaining 2.1 bcf (26.6%) of the total volume vented and flared during 1998. Of this, 1.0 bcf was flared in events over 1 hour in duration. This is a 12% increase in volume flared during events over 1 hour, up from 0.88 bcf flared in 1997. 50 51 1994-1998 COOK INLET FLARED VOLUMES including pilot & purge gas 1600000- 1400000 1200000 "' 1000000 '~ 800000 m 600000 0 400000 200000 Beaver Beluga Granite Kenai McArthur Middle N.

WELL INFORMATION AND RECORDS Copies of the following material on released wells can be obtained from the office in accordance with 6AAC 95.010 through 900. - directional surveys - completion reports - core descriptions - drill stem test reports - drilling histories - production history Computer tapes of electric logs and bottom-hole pressure surveys are available only through the Commission. DRILLING AND PRODUCTION DATA Drilling data are tabulations of monthly drilling figures for exploratory, development, and service wells. Production data are tabulations of the monthly, yearly, and cumulative production or injection volumes for each well in the state's producing fields. Requested data can include whatever releasable information is sought, and can be produced in whatever tabulation is desired to accommodate particular individual needs. For example, tabulations can be obtained showing oil production from each of Alaska's oil fields on a year-by-year basis from startup to the present. Similar tabulations can be obtained reflecting production and/or injection totals from individual wells, as well as listings of such things as all exploratory wells drilled within any designated area showing operator, well name and number, surface and bottom- hole locations, and completion status. Custom ordered tabulations on drilling and production statistics can be obtained either in printed form or on digital tape from Motznik Computer Service, 8301 Briarwood Dr. Ste 100, Anchorage, AK 99518; telephone (907) 344-6254; facsimile (907) 344-1759.
