Our adopted conventions for assigning APl numbers, permit numbers and well names did not specifically address expired or cancelled permits. This omission has caused some inconsistencies in the treatment of these kinds of applications for permit to drill. OPerators have asked us to adopt formal procedures for this class of permit application in order to prevent future database disparities. If a permit expires or is cancelled by an operator, the permit number of the subject permit will remain unchanged. The ,APl number and in some instances the well name reflect the number of preexisting reddlls and or multilaterais in a well. In order to prevent confusing a.canceiled or expired permit with an active well or multilateral these case sensitive well identifiers will be changed for expired and cancelled applications for permits to ddll. The AP! number for this cancelled or expired permit is modified so the eleven and twelfth digits is 95. The well name for a cancelled or expired permit is modified with an appended xx. These procedures are an addendum to the APl numbering methods described in AOGCC staff memorandum "Multi-lateral (wellbore segment) Ddiling Permit Procedures, revised December 29, 1995. AOGCC database has been changed to reflect these changes to this permit.

The location has been designed to provide containment of any drilling operation effluents that could be considered as pollutants. The ~190' x 190' x 10' deep reserve pit will receive and contain all drill cuttings, excess mud material, wash and drain water from around the rig, and have the capacity for use in the event of a severe well control problem. Sewage and kitchen waste water will be processed through a Steel Fabricators, Inc. biological treating system with excess sludge being incinerated and the disinfected liquid contained in a steel holding tank. A separate-sanitary holding pit is provided to store the treating plant effluent in the event of a system malfunction. A burning pit is located clear of the rig to permit emergency burning of any produced hydrocarbons resulting from well testing or an upset. All fuel will be stored in steel tanks; primary fuel tanks will be located in a plastic membrane lined fuel storage area. A primary feature of the drilling plan is to provide 9-5/8" x 13-3/8" annular injection capability. The well casing program is designed to set 13-3/8" surface casing through the major gravel sections and below any possible fresh water zones. The 9-5/8" protective casing will be set into the anticipated pressure transition zone and cemented to is61ate the saltwater sand sections from below the surface casing shoe to approximately 7000 feet for injection of lube oil, excess mud, melt water, waste waters, and well test liquids. Liquid levels in the sanitary holding pit and burning pit will be maintained below ground level after breakup to prevent migration of any liquid out of the pit while the reserve pit will be maintained at a minimum level at all times to provide for containment of well fluids in the event of an upset. All pits will be pumped out to a minimum level and waste water injected into the injection zone before abandoning the location. The entire operation is planned so that no fluids associated with the operation will be discharged on the surface outside the location. The drilling contractor will be required to develop a comprehensive SPCC Plan to prevent pollution as a result of any drilling rig operations. Drip pans will be installed under the engines and rig machinery. All oils, greases, and chemicals are to be stored within th~ protected areas. Good housekeeping will be stressed on all parts of the location with emphasis on minimizing contamination of the peripheral drainage from the pad Any minor spill of oil will be collected using sorbent materia~ for disposal in the incinerator. Page 2 ~'-~. Personnel safety and well control are the uppermost factors in well design and operational planning. Sufficient data are available to plan the well for evaluation of the geologic objectives, provide for subsurface disposal of waste water, and conduct a safe drilling operation. Advanced abnormal pressure technology will be used to predict and detect changes in formation pressure to permit adjusting the casing and drilling fluid program to control the well. Emphasis will be placed'on well control equipment and procedures to permit circulating out a formation "kick" in an orderly manner if it should be necessary; any hydrocarbons in the influx will be diverted to the burning pit and burned. In the event of an unplanned upset resulting in uncontrolled well flow, the following basic procedures will be followed: lo Divert flow to burning pit as the first defense against a spill. Switch the flow to the reserve pit.when the safe working level is approached in t~e burning pit. The design capacity of the reserve pit is 64,000 barrels which will be maintained at a maximum, practical working capacity at all times by keeping mud and fluids use at a minimum and pumping fluids into the injection annulus when possible. 2. Prepare plans for drilling a relief well from an alternate location. · The well fluids will be ignited at the wellhead, if the situation warrants, only after discussion with proper governmental agencies and Exxon management. Major supplies of mud, cement, casing, fuel, and miscellaneous supplies will be transported over winter roads or flown directly to location. After breakup, light consumables will be transported by helicopters. A Rolligon will be on location for any local movement of water or fuel as permitted by land conditions. A Catastrophe Organization consisting of specifically designated personnel will be activated to cope with an emergency such as an out-of-control drilling well. The Drilling Section of the Catastrophe Organization is responsible for performing the well control function which includes all surface well control procedures as well as plans for a relief well. Immediate action will be taken to minimize environmental damage and institute cleanup operations. The basic relief well plan involves construction of another surface location approximately 2,000 feet upwind (east) of the original well's surface location. The most likely time for a severe well control problem to develop would be late March, which would Page 3 '~- ' allow sufficient time to construct the location and spud the relief well before breakup. The planned relief well location would permit the relief wellbore to penetrate the flowing zone near the out-of- control well with a 2,000 foot horizontal displacement. In the event insufficient time is available to initiate the relief well, a barge rig operation could be mobilized after breakup to drill a relief well. Both relief well plans are predicted on'emergency approval ©f all phases of the operation by all state and federal regulatory agencies.

Exhibit B: Proposed winter access routes from Prudhoe Bay to drill site. Natural Environment The proposed drilling location shown on Exhibit A lies approximately three miles southeast of Point Thomson Unit Exxon No. 3 and is situated 1.5 miles inland from the Beaufort Sea coastline. The surrounding terrain is a typical low lying coastal plain with scattered small lakes. Surface vegetation is typical tundra with mosses, lichens, grasses, and sedges being most dominant. Elevation of the proposed drill site is approximately 11 feet above sea level. The proposed well is in the continuous permafrost zone of Northern Alaska where the depth of permafrost is approximately 1,600 feet and the active surface layer or thaw zone is from one to three feet. Since the ground cover acts as insulation limiting the depth of the active layer, removal or damage to the ground cover, particularly in areas of any appreciable slope, is a major factor in causing erosion. Consequently, every possible effort will be made to protect the surface from unnecessary damage. There are no established roads, airstrips, housing, or other facilities in the area and, because of the nature of the terrain, heavy vehicular traffic can operate only during the winter season while the ground, streams, and lakes are frozen. Prudhoe-Deadhorse, located approximately 50 miles west of the location, is the nearest staging area and airstrip with facilities for handling cargo and housing personnel. Arctic climatic conditions include relatively cold temperatures year round. Strong winds, small annual precipitation, and visibility strongly influenced by the combination of winds and coastal sea ice condition are factors contributing to an extremely harsh environment. ( Page 2 Temperatures vary from a high in the 40 to 60°F range in the summer to a low of -50 to -60°F in the winter which, with the chill factor may reach -100°F or lower depending on the severity of winds· Surface winds are predominantly from the east at an average velocity of 12 miles per hour along the coast with a velocity range of 35 to 50 mph associated with winter storms· Total annual precipitation is in the range of 4 to 6 inches which includes 12 to 48 inches of snowfall· Various species of wildlife exist in the area. During the winter months, when the major part of activities are planned, wolves, wolverines, foxes, polar bears, and caribou may be present. Bird life is limited primarily to the raven and ptarmigan, with waterfowl and most other birds having migrated from the area for the winter. Construction and Operating Plan Loffland Rig No. 162 and a 78 man Exxon owned camp will be used in drilling Alaska State "B", No. 1. This rig and camp will be moved from the Point Thomson No. 4 drill site which is approximately 11 miles northwest of the proposed location. Contingent upon regulatory approval, construction of the drill site will be commenced as soon as possible following completion of the construction of the drill site for Exxon Point Thomson No. 4 so that construction of both drill sites will be complete prior to breakup in the spring of 1980. Tentative access routes are depicted on Exhibit B. The proposed sequence for preparation of the subject drill site is as fOllows:* l· Construct an overland temporary ice road, connecting with Ocean Ice Road, extending from Point Thomson Unit No. 3 to Alaska State "B" No. i as shown on Exhibit A. 2~ · Move in and activate mobile construction camp. Move in equipment and construct drilling pad, Alaska State "B" No. 1. · Upon completion of drilling pad, demobilize construction camp and equipment. · After freeze-up in fall of 1980 construct ice road from Point Thomson Unit No. 4 to Alaska State "B" No. 1. 6. Move in drilling rig and EXxon camp from Point Thomson No. 4. · Repair haul. roads as necessary using maintainer and water trucks. * Present shortage of rigs on the North Slope requires that Loffland Rig No. 162 be used in drilling AlaSka State "B" No. 1 directly following completion of Point Thomson Unit No. 4. Should another rig become available in sufficient time to permit its movement to the location prior to spring breakup 1980, it will be substituted for the Loffland rig and' the plan of operation will be revised accordingly. Page 3 The drill site layout for Alaska State "B" No. 1 will be approximately 720' x 570' as shown on Exhibit A. In constructing this site, a two inch thick preformed layer of polystyrene insulation will be placed on the tundra for thermal protection. A gravel pad, having a minimum thickness of 16 inches, will be constructed over the polystyrene. The gravel for this pad, totaling approximately 11,000 cubic yards, will be salvaged from the pad at Point Thomson No. 3. Rubber tired loaders and belly dump trucks will be used for the loading, hauling, and placement of this gravel at the new location. The planned drilling location will accommodate the rig and equipment, camp, and support facilities. The pad has been designed to act as an insulation barrier to prevent thawing of the permafrost. Wooden piling and matting will be used under the drilling rig and mud pumps for stability and as a further aid in preventing permafrost degradation. Berms will be constructed around all pits. A 190' x 190' x 10' deep reserve pit will be used to retain cuttings, excess drilling fluid, and drainage around the rig. The level in this pit will be kept low to prevent migration of fluids and provide capacity in case of an emergency such as a severe well control problem. A 60' x 60' x 6' deep burning pit will be located a safe distance from the rig to permit routine burning of test gases and the emergency burning of test liquids and combustible waste materials. Welded steel tanks, located in a 60' x 130' x 6' deep plastic lined pit, will provide 425,000 gallons of fuel storage capacity. All tundra and topsoil excavated from the pits will be used as berms around these pits. This will expedite site rehabilitation. The proposed well will be designed for annular injection which will permit subsurface disposal of wash and melt water, sewage effluent, waste lube Oil, excess drilling fluids, and well test liquids. An ice landing strip, approximately 2000 feet long, will be constructed with snow and water to facilitate air transportation during winter operations. Helicopters will be the primary mode of transportation during summer operations. The drilling and evaluation operations for this well will require six to seven months. After completion of the well, the rig may be left on location until the following winter. Major supplies of mud, cement, casing, and miscellaneous drilling supplies will be transported to the location and stockpiled before spring breakup so as to permit operations to continue through the summer. Sufficient fuel will be stored on site to permit operations to continue into spring breakup. Additional fuel required for summer operations will be handled by Rolligon Page 4 or Barge. If bulky equipment must be delivered on short notice or large shipments can be accumulated, an ocean ice landing strip off the coast for Hercules aircraft may be constructed. After breakup, personnel and light consumables will be transported by helicopters or other State approved means. All support equipment not required for summer operations will be moved out before breakup. Drill Site Facilities The following described facilities will be provided to support camp and rig operations: 1. Sewage Disposal A Steel Fabricators, Inc. biological sewage disposal unit, owned by Exxon, which complies with the require- ments of the State of Alaska and the EPA for water quality in the area of operation will be installed for the treatment of sanitary sewage. Treated effluent from this unit and gray water, which is discharged from kitchen and shower areas, will be combined in a steel storage tank and used for drilling mud or rig wash water. A 25' x 60' x 6' deep earthen holding pit will be provided for the temporary storage of sanitary sewage in case of an upset of the treating unit. 2. Water Supply Potable water for the camp facilities will be hauled from state approved small lakes near the rig and a large, eight-foot deep lake in Sections 22 and 23, T9N, R23E, UPM, approximately 2.5 miles southwest of the location. A snow melter will be used to supplement the water requirements until shallow lakes closer to the rig thaw in the summer. The water will be processed through a Steel Fabricators, Inc. water treating unit before use in the camp. Additionally, treated sewage effluent and gray water from the camp will be used for mud and rig wash water. 3. Garbage and Waste Disposal Burnable garbage and wastes will be disposed of in a McNaulin-Goder Model-1510 trash incinerator unit. Some of the more readily combustible products, such as paper, wood, and cardboard, may also be open burned. Noncombustible wastes, such as scrap metal, tires, batteries, and drums, will be hauled to Deadhorse and final disposal will be in accordance with State Waste Management requirements. Page 5 Development Plans If oil is discovered in sufficient quantities to warrant future development, the Prudhoe Bay to Valdez oil pipeline will be the probable marketing outlet from the area. Oil and casinghead gas would be processed through central oil gathering facilities with oil being pipelined to the Trans-Alaska line passing approximately 50 miles to the west. If commercial quantities of gas are discovered, development of a gas market outlet will be related to studies to market gas from the Prudhoe area. Surface Protection and Restoration Plan As previously mentioned, precautions will be taken to protect the surface by not beginning operations until after freeze-up and by using snow and ice roads during winter. At the completion of the well, the location and adjoining area will be cleared of all waste materials. All pits will be back- filled and leveled. Special procedures for drilling and subsurface equipment are required by the unique characteristics of the permafrost area. Casing cement used through the permafrost zones is of special composition to reduce possibility of freezing and other casing problems. Casing is run and cemented through the permafrost, and in the event of production or interruption of operation, the uncemented casing must be protected by the use of non-freezing fluid.
