Johnston, Commissioner Chairman of Commission 1996 ANNUAL REPORT -- - - - -- - - -, State of Alaska Alaska Oil & Gas Conservation Commission 1996 Annual Report INTRODUCTION The Alaska Oil and Gas Conservation Commission is pleased to present the 1996 Annual Report. In the course of fulfilling statutory obligations, the Commission compiles and maintains a comprehensive data bank of drilling, production and reservoir statistics. Selected portions of these statistics are published in this volume to summarize Alaskan petroleum industry activity in 1996. Alaska's total liquid hydrocarbon production (oil and natural gas liquids) in 1996 was 544 million barrels, for an average rate of 1.49 million barrels per day, a 4.0°,10 decline from 1995. This rate of decline is roughly equivalent to last year's. Oil production accounted for approximately 511 million barrels, and natural gas liquids approximately 33 million barrels. ' Total dry and casinghead gas produced was nearly 3.39 trillion cubic feet, of which approximately 2.93 trillion cubic feet was reinjected to support enhanced oil recovery operations. Of the approximately 462 billion cubic feet of net gas produced, 227 billion cubic feet was used to fuel oil and gas operations, 7 billion cubic feet was flared, and 228 billion cubic feet was sold. Enhanced oil recovery water injection totaled nearly 962 million barrels or more than 2.6 million barrels per day, a volume that exceeds liquid petroleum production. There were a total of 884 active water and gas injection wells statewide at year end. Exploratory drilling activity consisted of 12 new pool wildcats on the North Slope' and 2 in Cook Inlet Basin. Total exploratory footage drilled for the state was nearly 113,000 feet. Development and service wells drilled in 1996 totaled 158 on the North Slope and 5 for Cook Inlet Basin. Total development and service well drilling exceeded 1.4 million feet. Drilling levels and enhanced recovery operations in 1996 continued at historically strong levels in a trend evident since 1991. These factors combined with recent exploratory successes on the North Slope suggest an expansion of industrial activity and continued moderation in overall production decline for 1997. The Commission issued at total of 28 Conservation Orders, 1 Area Injection Order, and 1 Disposal Injection Order in 1996. i ii The Commission also completed a major rewrite of its regulations governing oil and gas drilling, development and production in Alaska. The new regulations streamline permit and reporting requirements, address new technology, including coil tubing drilling, establish requirements for offshore location clearance, provide flexibility in bonding, clarify enforcement procedures and enhance provisions protecting health, safety, and the environment. The new regulations are undergoing Department of Law review, and should become effective in late 1997. ~-,~ Mary c.~ar~urn Commissioner -- - - --- - ~ - - ---- - - Alaska Oil and Gas Conservation Commission The Commission is an independent, quasi-judicial agency of the State of Alaska. It is established under the Alaska Oil and Gas Conservation Act (AS 31). 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. The Commission acts to prevent waste, protect correlative rights, improve ultimate recovery and protect freshwater. It administers the Underground Injection Control (UIC) program for oil and gas wells in Alaska. It serves as an adjudicatory forum for resolving oil and gas disputes between all owners, including the state. The Commission carries forth 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. The Commission's FY'98 operating budget as submitted to the Legislature is $1,688,400, which includes $100,000 from the federal government for administering the UIC program. The Commission is funded by a special tax established by the Legislature. The Oil and Gas Conservation Tax is 4 mils per barrel of oil and per 50 Mcf of gas. Tax proceeds in 1997 should be about $2.0 million. (1,000 $) $3,000 Yearly Budget $2,500 1*'1- - 11 1'1 ~ III I I I ..

exploratory wells and on wells expected to penetrate shallow gas sands; and on new-rig or reactivated-rig start-ups where a diverter is required. 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 less 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 DNR/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 LACTs every quarter, and topping plants every six months. NOTE: LACT stands for "lease automatic custody transferIJ. ...-...-. - - - .--..., --8111¡ ~ - ...-..- ---- -" - - ~.~ "'"'"- FIELD INSPECTION PERFORMANCE This is an analysis of the performance of the field inspection program for the 1996 CALENDAR YEAR compared to the goals stated in "Field Inspection Goals". DIVERTERSl We witnessed 31 Diverter Tests, but more significantly, we witnessed diverter tests on all 6 of the Remote Exploratory Wells for a coverage of 1000/0. BLOWOUT PREVENTION SYSTEMS: We witnessed 97 BOP tests. Our goal was at least one test on each rig every two months and on the surface casing of all exploratory wells; since there were approximately 115 rig months, our goal was 67 tests; we exceeded the desired number of BOP tests. More importantly, we witnessed at least one BOP test on each of the exploratory wells. RIG INSPECTIONS: We conducted 56 RIG BOP System inspections. SAFETY VALVE SYSTEMS: There are approximately 1,950 Active Production and Injection Wells requiring safety valves; the wells are required to be tested every 6 months and our goal is to witness 250/0 of those tests. We witnessed 1,031 test or 26% of the required number of tests. WELL HOUSE INSPECTIONS.;. Inspections were conducted on a total of 1,001 well head and well house systems on the North Slope and in Cook Inlet. MECHANICAL INTEGRITY TESTS: There were 832 Enhanced Recovery and 52 Disposal Wells at year end 1996. Our goal is to witness 25°,10 of the routine tests (one MIT every four years), the initial test on all new and/or converted wells, and the MIT following well repairs. We witnessed a total of 197 MITs last year WELL BORE PLUGS: We witness plugging and abandonment operation on six remote exploratory wells and 38 plugging operation on development wells, most of which were for zone abandonment so the wells could be redrilled. LOCATION CLEARANCE: We witnessed 42 Location Clearance Inspections. METERING~ Gas meters: We witnessed calibrations at 19 of the 20 facilities scheduled for inspection (95%) and 26 of the 27 scheduled meter calibrations(96%). Oil meters: We witnessed meter provings at 52 of the 56 facilities scheduled for inspection (92 °,10); and 156 of the meters scheduled to be proved. Additional provings occurred at PS-1 Lisburne Meters. Prover Certifications: We witnessed certification of 5 provers: 1) Alyeska master prover, 2) PS #1 Prudhoe Oil Pool Prover, 3) PS #1 Lisburne Oil Pool prover, 4) Endicott prover at MPI Endicott, and 5) the Milne Point prover. -46- AOGCC FIELD INSPECTION SUMMARY WITNESSED TESTS AND INSPECTIONS 1980 THRU 1996 Statistics Drilling Rigs Dlverters & BOPE Systems Safety Valve Systems Mech.

Effectively 4 inspectors in-the.field due to resignation, reassignment, and leave for family illness. Gas Disposition Two years have passed since the Commission revised the requirements for reporting Gas Disposition. There was previously no time limit for flaring events. Many facilities had daily flaring limits that were set by conservation orders. Operator's applied for administrative approval to the conservation orders in order to exceed the daily limits. The regulation change became effective January 1, 1995. Operators are now required to report individual events over one hour in duration and provide detailed explanations of these events. As a result, investigations conducted in 1995 resulted in 35,725 mcf declared waste. No investigations during 1996 resulted in declarations of waste. Total gas flared or vented in 1996 was 7.1 billion cubic feet (bcf), down 19.4% from the 1995 total of 8.8 bcf ,and a 46.7% decrease from the 1994 total of 13.3 bcf. Of the 7.1 bcf flared in 1996, 3.8 bcf (53.4°,10) 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, 1.8 bcf (25.5%) was flared in events under 1 hour in duration, and 1.5 bcf (21.1°,10) was falred in events which lasted over 1 hour in duration. Arctic North Slope North Slope operations contributed 5.8 bcf (81.7°,10) to the total volume vented and flared for 1996. Of this, 1.1 bcf was flared in events over 1 hour in duration. This constitutes a 51 °,10 reduction from the 1995 volume (2.26 bcf) flared in events over 1 hour in duration. Cook Inlet Basin Cook Inlet operations made up the remaining 1.3 bcf (18.3°,10) of the total volume vented and flared during 1996. Of this, 0.34 bcf was flared in events over 1 hour in duration. This is a 45°,10 reduction in flaring events over 1 hour, down from 0.62 bcf. -47- Mscf '" '" w w .¡::. .¡::. 0'1 0 Ò1 0 01 0 01 0 01 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 January February March en ~ » April ~ m ~ C m May S 0 I z ~ June I :J: I I ..¡::-. s r- ex:> -< I 0 ::J ." r+ ::::r r- July » ::D m C August < 0 r- C S September m en October November December '8-.
