Seamount Jr. Commissioner Robert N. Christenson, P.E., Commission Chair Cammy Oechsli Taylor Commissioner OIL 1999 ANNUAL R-EPORT INTRODUCTION State Of Alaska Alaska Oil & Gas Conservation Commission 1999 Annual Report Each year, the Alaska Oil and Gas Conservation-CommissiOn compiles a Wide variety of information related to petroleum exploration and production operations. This annual report is based on a portion of that information. It summarizes the historical activity of the petroleum industry within the State of Alaska, with special emphasis placed on operations undertaken during 1999. During 1999, Alaska's total production of oil and natural gas liquids was 415 million barrels, which is an average rate of 1.14 million barrels per day. Oil production accounted for approximately 383 million barrels, and natural gas liquid production totaled about 32 million barrels. This represents a production decline of 10.3 percent from 1998 and an 18.2 percent decline from 1997. Produced dry and casinghead gas totaled nearly 3.38 trillion cubic feet, a decline of 1 percent from 1998. Approximately 2.92 trillion cubic feet of casinghead gas were re-injected to support enhanced oil recovery operations, a volume that is unchanged from 1998. Of the 463 billion cubic feet of net gas, 222 billion cubic feet were used to fuel oil and gas operations, 7 billion cubic feet were flared and 234 billion cubic feet were sold. Water injection for enhanced oil recovery totaled nearly 936 million barrels, or nearly 2.6 million barrels per day. A total of 862 water and gas injection wells were active. At the end of 1999, there were 3,336 active wells in the state, a 4 percent decrease from 1998. The 1999 active wells include 2,266 oil development wells, 154 gas development wells, and 916 service wells. Total development and service drilling exceeded 624,000 feet in 104 wells on the North Slope and 8 wells in the Cook Inlet. Total drilled footage decreased by nearly 67% compared to 1998. The footage decrease is due to the combination of issuing 50% fewer permits to drill in 1999 and the increasing trend to re-drill existing well bores. Recycling existing wells is becoming an increasingly common method of recovering additional hydrocarbon reserves from known accumulations. Exploratory drilling consisted of 5 wildcat wells on the North Slope. Total exploratory footage drilled within the state during 1999 was nearly 50,500 feet. New development projects on the North Slope included; 1) advanced planning for a miscible injectant EOR flood at Point Mclntyre, 2) a waterflood at the West Beach Oil Pools in the Prudhoe Bay Unit, 3) initial assessment of the Kekiktuk and Killian Undefined Oil Pools in the Badami Unit, and 4) development operations in the Alpine Oil Pool in the Colville River Unit. In the Cook Inlet region, iOcean Energy Resources, Inc. continued development of coalbed methane resources with a four-well pilot project in the Matanuska Valley near Houston, Alaska. Forcenergy Inc. continued its progress toward development of the Redoubt and West Foreland fields within Cook Inlet. During 1999, the Commission issued two Conservation Orders, ten Conservation Orders providing spacing exceptions, three Disposal Injection Orders, one Aquifer Exemption Order, and nine Administrative Approvals. We also processed 131 permit to drill applications, a 50 percent decrease from the 263 applications processed during 1998. The Commission also completed a major revision of its regulations governing oil and gas drilling, development and production within Alaska. These new regulations were reviewed by the Department of Law, and became effective November 7,11999. Operating companies are continuing their efforts to increase recovery of reserves from older, established Alaskan fields. Throughout the 1990's, increased numbers of development wells were recycled by re-drilling to new bottom hole locations. Re-drilling of wells has become increasingly common due to rapid advances in directional drilling and coiled tubing drilling technology. Re-drilled wells are now routinely used to recover bypassed reserves, accelerate production or improve injection conformance. Figure 1 presents the historic trend for drilling permits approved by the Commission from 1990 to 1999. The lower, dashed section represents the number of new wells permitted each year. The upper section on the figure signifies the total number of wells permitted each year, which is a combination of new wells plus re-drilled wells. The percentage of re-drilled wells increased consistently from 8 percent in 1990 to 61 percent in 1999 (Figure 2). This trend is especially evident in the Prudhoe Bay Field: during 1999, every reservoir penetration drilled within the field was a re-drill through an existing well bore. We remain dedicated to responding to public requeSts for information related to the hydrocarbon resources of the State of Alaska. Users of this report are invited to submit suggestions for its improvement. Cammy Oechsli Taylor Commissioner Robert N. Christenson, P.E.

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 in Alaska. It serves as a forum for resolving oil and gas disputes between all owners, including the state. The Commission carries forward 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. In 1999, the Legislature revamped the funding mechanism for the AOGCC. The legislation repealed the oil and gas conservation tax and instituted a program receipt system designed to provide stable funding. The new law requires operators of wells to pay an annual regulatory cost charge to the Commission proportional to volume of oil and gas produced from each well and the volume of fluids injected into wells. The Commission was appropriated a budget for FY 2000 of $2,701,300 and authorized four additional professional staff positions. The Commission is currently developing regulations to administer the regulatory cost charge program. -.

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 that may encounter high pressure zones. Perform BOPS Inspections and witness BOPE Test 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 re-tests, 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-over operations when the tubing and/or packer have been replaced. We 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 plugging and abandonment operation (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 well abandonment locations to ensure well head casing has been cut-off below ground level, plugged properly, casings are covered with a steel marker plate, and ensure that all junk and equipment have been removed. Ensure the site has no open pits or depression on the pad to pond water and that the pad has been graded close to original condition. The Commission has waived this 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 witness minor calibrations 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'transfer". FIELD INSPECTION PERFORMANCE This is an analysis of the performance of the field inspection program for the 1999 CALENDAR YEAR compared to the goals stated in "Field Inspection Goals". DIVERTERS: We witnessed 11 Diverter Tests. Diverter tests were witnessed on 3 of the 5 remote Exploratory Wells for coverage of 60% (whiteout conditions precluded some inspections). BLOWOUT PREVENTION SYSTEMS: We witnessed 89 BOP tests. Our minimum goal was one BOP test on each rig every two months and on the surface casing of all exploratory wells. There were approximately 152 rig months. We exceeded our minimum goal of 76 BOP tests. Coverage 117%. RIG INSPECTIONS: We conducted 73 RIG BOP System Inspections. SAFETY VALVE SYSTEMS: There are approximately 2313 active production and injection wells requiring safety valves. The wells must be tested every 6 months and our goal is to witness 25% of those tests (50% of the wells annually). We witnessed 1700 LPS (Iow pressure sensors or pilots) (this is indicative of the number of wells tested) - the coverage is 147% of our minimum goal. WELL HOUSE INSPECTIONS: Inspections were conducted on a total of 2841 well head and well house systems on the North Slope and in Cook Inlet. MECHANICAL INTEGRITY TESTS (MIT): There were 885 Enhanced Recovery and 58 Disposal Wells at the end of 1999. Of these wells, there were 13 new and 12 converted wells. MIT's were witnessed on 18 of the 25 new and converted wells (coverage 72%) and 167 existingwells (those on four- year test cycle). Overall average coverage was 154% of the minimum goals. WELL BORE PLUGS: Four Remote Exploratory Wells were plugged and abandoned and one was suspended. We witnessed 7 of the 8 critical plugs in the exploratory wells that were plugged for a coverage of 87.5%. No other well bore plugs were witnessed. LOCATION CLEARANCE: Seven Location Clearance Inspections were conducted. METERING Gas Meters: We witnessed calibrations at 16 of the 18 scheduled inspections- 89%; of the 24 meters scheduled for calibration, we witnessed 33 - 73% The average coverage [(facilities + meters)/2] is 81%. Oil Meters: We witnessed meter provings at 60 of the 62 scheduled facilities - 97%; of the 136 meters scheduled to be proved, we witnessed the proving of 187 meters - 138% (additional provings were witnessed at PS-1 Prudhoe, Lisburne, Kuparuk and Badami meters). The average coverage [(facilities + meters)/2] is 118% for the combined. Through the metering facilities we witness at Pump Station 1 and Kuparuk flowed 88% of the crude oil produced in Alaska during 1999. At thes9 facilities, we witnessed the provingof 104 meters vs. our goal of 78 meters. We achieved 133% of our minimum goal at these facilities. 34 AOGCC FIELD INSPECTION SUMMARY 1999 Statistics Well Abandonment Oil & Gas Meters YEARLY WITNESS TESTS AND INSPECTIONS TABLE Drilling Rigs Diverters & BOPE Safety Valve Systems Mech.

Five Inspectors 3 Months, Four Inspectors for 6 Months, 3 Inspectors for 3 Months. Gas Disposition Although flaring in 1999 decreased statewide, increases were noted in the Endicott Field on the North Slope due to volume accounting changes and from a frozen pipeline in the Granite Point Field of Cook Inlet. Total gas flared or vented in 1999 was 7.2 billion' cubic feet (bcf), down 12% from the 1998 total of 8.2 billion cubic feet (bcf), down 13% from the 1997 total of 8.3 bcf and up 1% from the 1996 total of 7.1 bcf. This was also an 18% decrease from the 1995 total of 8.8 bcf. Of the 7.3 bcf flared in 1999, 3.8 bcf (52%) 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 (28%) waS flared in events under 1 hour in duration, and 1.4 bcf (20%) 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 into 1998 events resulted in 12,383 mcf declared waste. Investigations are continuing into several 1999 incidents. Arctic Slope North Slope operations contributed 5.39 bcf (74.2%) to the total volume vented and flared for 1999. Of this, 0.85 bcf was flared in events over 1 hour in duration. This constitutes a 44% decrease from the 1998 volume (1.5 bcf) flared in events over 1 hour in duration. Cook Inlet Basin Cook Inlet operations made up the remaining 1.87 bcf (%) of the total volume vented and flared during 1999. Of this, 0.62 bcf was flared in events over 1 hour in duration.
