Reference: Issuance of Permanent Closure Approval for drilling waste reserve pits at Production Drill Sites 1D, 1L, and West Sak Pilot Pad located in the Kuparuk River Unit, and Exploration Drilling Sites West Sak 11, and Colville #1 Lisa L. Pekich Sr. Environmental Coordinator ConocoPhillips Alaska Inc. PO Box 100360 Anchorage, Alaska 99510 Dear Ms. Pekich: The Alaska Department of Environmental Conservation (ADEC) has completed review and public notice for permanent closure approval of the inactive reserve pits at the above references production pads located in or near the Kuparuk River Unit of the North Slope Oil Fields. The closure applications and corrective action plans provided the required information describing the history and conditions of the reserve pits, results of required water sampling, and assessment of the potential risks posed by the drilling waste to human health and the environment, as well as notice of completed corrective actions. All drilling waste, totaling thousands of cubic yards, was excavated from the production site reserve pits and the waste was capped in place at the exploration sites. Before and after waste excavation or capping, the pits were tested for the presence of hydrocarbon sheening and trace metals. Trace amounts of residual hydrocarbon sheen may remain in some production site pits. All drilling waste has been excavated from the production sites and trace amounts residual sheening is not considered a risk. ADEC has determined that the reserve pits do not present a material or probable risk to the public health or the environment. Public notice requesting comments on the closure requests was published February 25 and 26, 2004 in the Anchorage Daily News and posted on the state web site February 24th 2004. No public comments objecting to closure approval were received in response to this public notice. ADEC has determined that the reserve pits at these sites meet the closure requirements of 18 AAC 60.440. Closure Approval Under authority of 18 AAC 60.440 (j), ADEC grants permanent closure approval to ConocoPhillips Alaska Inc. for all inactive reserve pits at the following sites: Wel1/Production Pad Name tDrill Site 1D \J...~~t'.:J"--C:Ye..f\ Drill Site 1L West Sak Pilot Pad \'\~- ~/WestSakll 1) Þ Colville # 1 \ \~S-O~\ API Number Location Landowner Numerous Kuparuk River Unit DNR Numerous Kuparuk River Unit DNR Numerous Kuparuk River Unit DNR 50-029-20275-00 Kuparuk River Unit DNR 50-103-10002-00 Section 25, T 12N, R 7E, UM DNR » ..

Build 2 mile ice road as per permitted map. . Using a coiled tubing unit, displace the diesel in the well with a non-freezing kill weight brine (10.3 ppg) (approximately 100'). Note: There is no tubing in the well and the tubing spool has been removed. 3. Test 7" casing to 2,000 psi. If the casing tests OK, go to Step 4. If it leaks off more than 10% in 15 minutes, squeeze as follows: Set a cement retainer @ 2,338' (7" 29 ppf L-80) The 2,338' depth was chosen as a minimum of 100' below the DY collar in the 7" casing. The retainer can be deeper, but should not be shallower. Test below the retainer to 2,000 psi to make sure the leak is above it. If the leak is below the retainer, squeeze leak with Class G cement (950 sx maximum). If the leak is above the retainer, lay a cement plug from 2,338' up to 1,705' with Class G cement (approximately 110 sx). The 1,705' depth was selected to be 100' above the FO collar at 1,805'. WOC 12 hr, then retest the 7" casing. e If a retainer or plug was not set in Step 3, set a bridge plug @ 2,338' (7" 29 ppf L-80) The 2,338' depth is a~minimum of 100' below the DY collar in the 7" casing. The plug can be deeper, but should not be shallower. Lay a cement plug from 2,338' up to 1,705' with Class G cement (approximately 110 sx). The 1,705' depth was selected to be 100' above the FO collar at 1,805'. . Test 7" X 13-3/8" annulus to 1,500 psi. If the annulus holds pressure, displace the 7" X 13-3/8" annulus by running 1" pipe to 150' and displacing the arctic pack fluid, then cement the annulus to sudace with arcticset type cement. If it leaks, down squeeze as follows: Down squeeze the annulus with sufficient volume to displace the annulus plus 100 sx of Arcticset type cement. This would be approximately 1,300 cf of cement + 100 sx (~750 sx total). 6. Cut off the casing and wellhead 3' below grade level. 7. Set a bridge plug at 200' in the 7" casing. 8. Set a cement plug from 200' to surface in the 7" casing. 9. Cement any unfilled annulus. 10. Weld on cap and install abandonment marker. Marker to read: ARCO Alaska, Inc.

Section ll0(a) of the regulations states the Commission will, in its discretion, approve the suspension of a well if the well is capable of producing hydrocarbons in paying quantities or is reasonably demonstrated to have future value as a service well. Section 105(e) states that "[e]ach well to be abandoned or suspended must be plugged...to prevent the movement of fluid either into or between freshwater and hydrocarbon sources and to _prevent all other fluid migration within the well bore." In compliance with Section 170(a) of the regulations, "It]he location of an abandoned well onshore or upon a historically stable island must be cleared within one year following well abandonment .... " Section 170(b) provides the means for an extension of time if a valid reason exists, and the well bore is properly plugged. - .. - _-.-~.~;i July 31 1986 We are, therefore, requesting you to submit Form 10-403, Application for Sundry Approval, with a program which will bring the status of these.wells into compliance with the new regulations and provide a schedule for this stn~mer when our field inspectors can accompany your representatives to the well sites for location clearance inspection.

Introduction The exploration well West Sak ll was tested in February, 1978 in order to investigate the flow andhydrocarbon potential of the reservoir sandstones contained within The Kuparuk River Formation in this area and to obtain down-hole and separator samples of the produced fluids. Two potential hydrocarbon-bearJ_ng zones were delineated from the DIL/LLS/GR/SP and FDC/CNL/GR logs. The reservoir performance of these zones was investigated using two production tests. The first production test was designed to obtain flow and pressure measur~ts on the lower zone and to sample the produced fluids. Whilst flow into the well-bore did enable down-hole samples of the reservoir fluid to be obtained, the flow potential of this zone was insufficient to produce fluid to surface. q/ae second test, performed on the two zones combined, was designed primarily to fully investigate the reservoir as far as the proposed interwelldistance for development of the field. On the basis of con- clusions drawn from the test of East Ugnu ~1, this would require a stabilized flow period of seventy-two hours followed by a buildup period of equal duration. Although reservoir fluid was produced to surface in this test, the constant surging behavior of the well prevented the attainment of a stable flow condition. The test was therefore termi- nated prematurely after a total of seventeen hours and twenty-seven minutes flow with the primary objective unfulfilled. Separator oil and gas samples and downhole P.S.T. samples were obtained for P.V.T. analysis during this second production test. 2. Summary The collection of transient pressure data under stabilized flow conditions was not achieved in the two production tests performed on West Sak 11. The first test on the lower zone of interval 5822-5835' BKB and 5840- 5850' BKB failed to produce reservoir fluid to surface. In the second test, on the lower zone combined with the upper zone of interval 5778' - 5806' BKB, hydrocarbons did flow to surface. However, flow was very intermittent andunstable, providing problems in separation. Average flow data for this period are presented below although the constant surging gives little validity to an averaging process: Production Test 2 Average Flow~Data Choke Separator Separator G.O.R.* Initial Final Initial Size Oil Rate* Gas Rate WHP ~4P BHP (64ths) (BBL/D) (MSCF/D) (SCF/BBL) (PSIG) (PSIG) (PSIA) 64 733 435 875 220 38 1161.3 *These values are uncorrected to stock tank conditions. To avoid creating backpressure on the well-head, the 500 bbl tank and Otis burners were redundant throughout the testing operations; the oil and gas were recombined after separation and flared.

D.D. with 2 7/8" tailpipe run below the packer to a depth of 5554 ft. The tailpipe comprised a wireline re- entry guide, Otis XN no-go nipple, Otis X nipple and two joints of 2 7/8" CS Hydril. Calcium chloride was used as the completion fluid. February 13, 1978 Nippled down the B.O.P. stack and flanged up the Xmas tree which was pressure tested to 5000 psi successfully.

The W.H.P. of 710 psig dissipated immediately with only slight unloading of the diesel cushion %krough the bubble hose being observed. 15.05 - 18.52 Well closed in for the initial P.B.U. 19.00 P.O.H. with the H.P. gauge. 20.00 R.I.H. with 1 11/16" hydrodome guns and re-perforated the intervals 5822' - 5835' BKB and 5840' - 5850' BKB. W.H.P. remained static at 450 psig during reperforation. 21.35 Rigged up and calibrated the H.P. pressure gauge and tempera- ture probe. R.I.H. and positioned the gauge at 5840' BKB. Allowed the H.P. to stabilise at this depth, recording pressure at 1 minute intervals. After stabilization was achieved, the gauge was raised to 5732' BKB, approximately 100' above the perforations, in order to reduce turbulence in the vicinity of the tool when flowing the well. February 16, 1978 01.14 - 10.31 Initiated the second flow period. The W.H.P. of 788 psigdissipatedimmediatelywiththe diesel cushion unloading very slowly through the open-ended pipe. Intermittent surging in this period caused fluctuations in the B.H.P. 10.31 - 11.00 Closed in the well and P.O.H. with ~e H.P. tool without recording any P.B.U. 13.00 Rigged up Otis on Schlumberger line and pulled the ball ~alve. 15.32 Rigged up a Guiberson Swabbing Mandrel with 6 MV cups in order to aid the well unloading process. February 17, 1978 01.27 R.I.H. with the swabbing mandrel. Unable to pass through the swab valve due to a combination of buoyant forces on the MV cups and pack-off grease tube blockage. P.O.H., repacked grease tubes and reduced the number of 55;cups to two. 04.45 R.I.H. with the swabbing mandrel. ~abbed down to 250' before losing swabbing efficiency due %o either fluid entry in%o the well-bore or worn MV cups. P.O.H. to change cups. 05.30 R.I.H. with swabbing mandrel and 3 MVcups. The fluid level ~as located 100' below the swab valve, the rise of 150' from the previous level being caused by fluid entry into the well-bore. Continued swabbing the well. 07.37 - 16.45 Replaced the swab cups and added an extra one. Swabbed down to 1650' BKB when the fluid level fell below the ball valve nipple. 19.30 - 20.16 R.I.H. with Otis G.S. pulling tool in order to detect the fluid level below~he ball valve nipple. However, this method proved too insensitive for accurate location of the fluid level P.O.H. 21.15 R.I.H. with the swabbing mandrel and 1N~Icup in order to locate the fluid level if it reappeared above the ball valve nipple. A feeler run wasmade every half hour but the level did not rise above the ball valve nipple. February 18, 1978 04.21 Rigged up H.P. pressure gauge and temperature probe. R.I.H. in order to locate fluid level. However, circuitry problems caused malfunction of both pressure and temperature sensors. P.O.H. %o repair tool. 07.30 R.I.H. with H.P. pressure gauge alone. As the pressures in the well-bore above the air - diesel interface were less than the threshold pressure of 200 psi for operation of the H.P. gauge, large erroneous pressure fluctua%ions were observed in this interval. Consequently, the fluid level could not be determined with any degree of accuracy. P.O.H. 09.00 R.I.H. with 4 swab cups on the mandrel and located the fluid level at 1550' BKB. Continued swabbing to 1650' BKB. · 13.00 Rigged up Schlumberger P.C.T. tool comprising a gradi~m~nometer, H.P. pressure gauge and t~rature probe. Located the fluid level at 2008' BKB and the interfaces between diesel, oil, calcium chloride and mud. An oil slug was found at 5540' BKB, just inside %he 2 7/8" tailpipe. During the three runs made with the gradiomanometer, this oil slug migrated only slightly. 21.10 Rigged up Schlumberger P.S.T. tool. R.I.H. twice and sampled the oil slug at 5540' BKB. The first sample was bled to atmospheric pressure for identification. The second was transferred to a sample bottle under pressure for P.V.T. analysis. February 19, 1978 01.00 - 02.00 Rigged up Otis on Schlumberger line. R.I.H. and set, tested and opened the ball valve. Filled the tubing with diesel. 10.00 R.I.H. to perforate the interval 5778 - 5806' BKB using two linked 24' and 4' 1 11/16"' hyperdome guns at 4 s.p.f. Initial misfire. 11.47 R.I.H. toperforate but misfi~ed again. P.O.H. and re-wired the guns together. 14.00 R.I.H. and successfully perforated the zone 5778 - 5806' BKB. The WHP did not increase as a result of the perforation of this upper zone. 15.20 Rigged up and calibrated the H.P. pressure gauge and tent0erature probe. R.I.H. and positioned the gauge at 5792' BKB, midway between the upper perforations. Performed a static temperature and pressure · survey at this depth before raising the H.P. gauge to 5683' BKB, equivalent to 5600' BKBand approximately 100' above the top zone. 19.13 Initiated the first flow periodof the second production test. Initialunloading was quite promising. 19.25 Switched the flow to the stock tank. The B.H.P. reached a fairly stable value before beginning a rapid decline which caused a decrease in flow-rate at surface. This pressure decline maybe attributed to obstruction in the perforations. 20.05 Surface flow ceased. The wing valve was partially closed, allOWing B.H.P to rise, and was then re-openedinaneffortto initiate flow again. ~apetition of this "rocking" procedure caused intermittent unloading of the well, with some gas breaking through to surface. 20.50 Altered the choke size from 64/64" to 48/64" in order to raise the' B'. H.P. 21.13 Increased the choke size to 1" again to improve the surface flow. The B.H.P. continued to rise with mudandhydrocarbon fluids being slowly unloaded. 21.40 Surface flow ceased with B.H.P. beginning to decline. 22.39 Well closed in to flush the separator. February 20, 1978 01.30 Oonmenced flow through the open-ended pipe. 02.00 Switched flow to the separator, flaring the gas and flowing the oil to the stock tank. 02.38 Bypassed the separator to relieve back pressure on the well-head and aid flow. 03.15 Surface flow ceased although the BHFP continued rising for a further 18 minutes. Fluctuation in the BHFP was reflected in the frequent surging in the flow rate at surface. 04.50 - 13.27 Closed in well to build up flow potential for further clean-up~ 13.27 - 00.07 Well flowed through a 1" choke to the separator, flaring gas and oil through the open-ended gas line. Surging necessitated periodic bypassing of the separator to the open-ended pipe. Three oil samples were taken at the separator at 14.14, 14:40 and 14:45 hrs. and three gas samples at 23:55, 23:58 and 00:02 hrs. February 21, 1978 00.07 - 20.10 Closed in well for the second P.B.U. 20.30 P.O.H. with H.P. gauge. 21.22 Rigged up Schlumberger P.S.T. tool. R.I.H. and sampled hydrocarbons three tin~s from5792' BKB, midway between the upper zone perforations. The samples were transferred to bottles under pressure for P.V.T. analysis. February 22, 1978 06.05 Rigged upOtis on Schlumberger line. R.I.H. and pulled the ball valve. P.O.H. 07.30 - 10.00 R.I.H. and set a plug and prong in the Otis PXN no- go nipple. P.O.H. The %ubingwas displaced to calcium chloridebeforebeing pulled. A cement plug was set on the packer and the well abandoned. Rowan Rig 29 was officially released at 06:00 hrs. on 24thFebruary, 1978. 4. Gas and Oil Rate Calculations Fluids produced during the second production test were separated using a single stage, three phase separator of 1440 psig working pressure. When operative, the separator worked efficiently without encountering any .foaming problems. To avoid creating backpressure on the well-head, the 500 bbl. tank was redundant throughout the flow period and the oil and gas were both flared through the open-ended pipe. The following gas and oil rate calculations are separator measurers, uncorrected to stock tank conditions. r ,~--r'~'GAS FLOW RATE CALCULATIONS O~' C --8 6Z-~3 SOHIO-BP ALASKA ........ ~I ET~ TYP~ D~~ S~OR ............

The API gravity of the oil was found to be 28.0 degrees at 60 degrees F. Three unsuccessful attempts were made to fill the 2 3/4 gallon chamber. Although pretest indications were good in all cases, migration of formation fines caused plugging of %he restrictor to the chamber and prevented sampling.

Fluid 8.1 Test Sampling Reservoir Fluid (P.S.T.) Samples Both production testing operations yielded reservoir fluid samples which were obtained using the Schlumberger P.S.T. tool. Samples in the first test were recovered from an oil slug introduced into the 2 7/8" tailpipe assembly by the swabbing operations. The sampling depth for the second pro- duction test was 5792' BKB, the midpoint of the upper perforated interval (5778 - 5806' BKB). below: The sample data is summarized Depth · Bottle No. Volume BKB (PSR-A Type) cc 5540 1 gal. plastic jerrican 5540 754A 650 2 5792 760A 650 2 5792 761A 650 2 5792 734A 650 8.2 8.2.1 Bottle No. W-943 W-4454 W-4478 8.2.2 Bottle No. Separator Samples 12D73 Sample Sample Date Time 2/18/78 21.30 2/18/78 23.35 2/21/78 23.36 2/22/78 00.15 2/22/78 05.10 The collection of separator oil and gas samples waspossible during the sporadic flow periods of the second production test.

Location of Facility This site is inland, about 20 miles west of the Kuparuk River and is about 12 miles south of Oliktok Point. It is central in Section 4, Township llN, Range 9E, L~niat Meridian, being 2,450'ft. from the south line and 2,078 ft. from the east line of said Section 4. ~4ppendix B (Drawing A84D-B-4) is a map showing its location. Site Description The site on which the drilling pad wiil be constructed is a tundra area with an elevation of approximately 85 ft. above sea level and about 6 miles west of the Ugnuravik River. The surface is typical tundra vegetation near a pot hole drainage way on damp ground with few ice wedges. All facilities, other than access ice roads, temporary ice berms constructed for secondary spill containment, and certain tankage vehicle parking areas will be located on a gravel pad w~rk area of approximately 300 ft. by 400 ft. Under normal conditions the welI site can be r~eached from the ARCO exploratory road after a 6.4 mile drive from the ARCO road. -1- 1.5 Time Period Covered by Plan Work ~will commence at the site as soon as the ice road can safely be bUilt to the site probably in December, 1977. It is expected that the drilling rig will be released in mid-April, 1978. 1.6 Name and Address of Operator The operator for this exploratory well drilling operation is: BP Alaska Inc. 3111 "C" Street P.

DESIGN AND OPERATING INFORMATION Site Drainage The drill site pad surface and work area has a minimum elevation of three feet above the surrounding area with 1:5:1 side slopes. Facilities located on the pad surface which might spill oil shall be surrounded by berms of ice and snow or gravel. A reinforced plastic membrane has been placed beneath the entire drilling rig structure. The membrane and the pad surface both slope into a sealed steel cellar which is permanently attached and sealed to the conductor pipe. Any oil or other contaminant which leaks or is spilled frcm drilling rig equipment will drain into the cellar from which it can be subsequently pumped and transported to an on-shore disposal pit. Fuel Storage and Transfer FaCilities As shown on Appendix B, fuel will be stored in steel tanks which will be surrounded by a snow and ice or gravel berm constructed for secondary containment. Once the berm is constructed it will be sprayed with water which when frozen will form an ice barrier. Fuel flow diagrams and transfer procedures are included in Appendix C, All personnel working in the fuel handling area will ~be thoroughly trained in these procedures. Blowout Prevention Program Equipment This rig will be equipped with a 20" 2000 psi W.P. annular diverter system installed on 80' of 20" H-40 94# conductor pipe while drilling 17-1/2" surface hole to 2200 ft. In the unlikely event that low pressure, low volume surface gas is encountered, the wellbore fluid can be diverted into storage and the gas allowed to vent to the -4- atmosphere. After running and cementing 13-3/8" 72~ N-80 surface casing at 2200 ft., a blowout preventer (BOPE) consisting of three 13-5/8" 5000 psi W.~P.-rams, a 13-5/8" 5000 psi W.P. annular preventer, and a two-choke manifold will be installed. These preventers are powered by an accumulator system with both nitrogen and manual back- up. After installation of the POPE, it will be thoroughly tested for leaks using diesel fuel. It will be tested at least w~_kly thereafter, as well as prior to drilling out casing shoes. Operational tests and crew drills will be conducted daily. Primary Well control will be maintained by over-balancing formation pressure with a column of drilling fluid. Autc~atic and manual monitoring equipment will be installed to detect any abnormal variation in the mud system and drilling parameters. A mud logging unit manned by experienced personnel will be in continuous use while drilling intervals where hydrocarbons are suspected and will monitor formation pressures, hydrocarbon~ shows, and loss or gain in the mud storage reservoirs. In the event that the well kicks, the BOPE will be used to shut in the well immediately and confine the pressure within a closed system. The pressures can be shut in at the surface without breaking down the casing shoe. Pressure resulting from a kick will be circulated out using the balanced bottom hole pressure method and the well will be restored to its normal operating condition. These personnel will be further supported by well-trained drilling crews approved by the Company. A. description of the Ccmpany's current -5- blowout prevention training program together with a copy of its "Drilling Operations Blowout Prevention ~mnual" is available for inspection by appointment. Company representatives assigned to the drill site receive extensive training in well control. 3.1 3.2 3. CONTINGENCY PLAN Response~ _.Organization The Drilling Supervisor shall take charge at the scene of an oil spill near the rig, and shall notify the on duty Field Coordinator without delay. The Field Coordinator shall provide oil cleanup assistance to the Drilling Superintendent utilizing rig-assigned personnel or bringing in additional personnel as required. He shall also notify the Environmental Engineer without delay, in aCcordance with BP Alaska Inc. Standing Instruction #3-76 and the SP~C plan covering the operation of the Prudhoe Bay field. The Environmental Engineer shall notify appropriate regulatory agencies and shall arrange for special cleanup equipment or outside spill cleanup teams as required by the circumstances. Cleanup Procedures Figure 3.1 shows in schematic form the various operations which might be involved in cleaning up any particular oil spill at this well site.

A spill event is any spillage of crude oil, product, or other harmful liquid under circumstances such that the ~Drkpad fill material or the surrounding area could become contaminated. Included would be such events as fuel loss through a broken hose, an overflow of oil contaminated mud during a well kick, or fuel overflow during tank filling. Not considered a spill event are any small spill beneath the rig or into the cellar provided the spill is completely contained by the oil-proof membrane and none is permitted to seep into the pad. Protect lives, property, etc. Take inmediate action as required to prevent fire and to protect personnel, property and wildlife. Construct snow berm as required. The spread of spilled oil can be restricted by construction of snow berms. The snow berm should encompass sufficient surface area to accon~Ddate the expected spill volume. Distillates will flc~ beneath the snow, so the area should be surveyed by testing the air near the surface with a gas chromatograph. Either of these methods should indicate the presence of hydrocarbons beneath the snow. The surface of the snow berm should be made impervious by spraying with water. Uncontrolled well. Conservative practices employed by BP Alaska Inc. make loss of well control highly unlikely. Key features of the blowout prevention program include: well engineered casing and c~/~nt~ systems to prevent migration of fluids outside of the wellbore, good mud control to prevent well kicks or lost circulation, well engineered and properly maintained blowout prevention equiument to control unexpected flows of fluid to the surface, and a well operated training program, including hands-on exercises, to ensure that men and equipment do the right thing at the right time. Attempt shutoff at surface. M~st uncontrolled wells are brought back under control by operations at the surface. Specific actions depend on the configuration of the wellhead at the time. Actions which might be applied include pumping weighted mud and lost-circulation material into the kill line, application of dry ice to the wellhead to freeze off the flow, and use of specialized (Red Adair) equipment. Drill relief well. It is expected that BP Alaska will have at least three other drilling rigs under contract at the time of drilling this well. Drilling sites and procedures will be determined based on specific conditions requiring a relief well. Kill well. Killing the flow from an uncontrolled well ~ires the injection of large quantities of fluid into the formation. Water for the well killing fluid will be obtained from the water source lake. See Appendix B (Drawing A84D-B-4). Pipes for delivery of the water should be insulated with snow to prevent freezing. -8- . 0 10. 11. 12. 13. 14. 15. 16. 17. 18. Scrape up spilled oil. At the ambient temperatures at wintertime in the Prudhoe Bay area, crude oil will be highly viscous, and not readily pumped in small diameter lines. The spilled oil should be picked up with earthmoving equipment (scrapers, front end loaders) for transport to an area where the oil can be safely burned. Addition of snow to the oil, as a sorbent, will probably improve the handling characteristics. Mixing of snow and oil can be done with bulldozers. Transport oil to burn pit. Oil can be transported to an approved burn pit by use of dump trucks or scrapers. If dump trucks are used their beds should be lined to minimize loss of oil enroute. Burn. After the oil has been delivered to the approved burn pit it shall be ignited. Use of more than one burn pit will permit continuous cleanup operation without the accumulation of large quantities of unburned oil in a burn pit. After breakup rig booms and skim. At the time of breakup a floating boom should be rigged encompassing the entire area affected by the spill. Initially, this boom can be placed in trenched lines or natural breaks in the ice. Skinmers and Oil Mop equipment shall be used to pick up any concentrations of oil in the area. Sorb. After the bulk of the spill has been picked up, final cleanup can be accomplished with sorbents such as 3-M Brand Oil Sorbent. Clean Gear, Inventory, Reorder. If this step is not carried out, materials will be consumed, equipment will become lost or unusable, and the "next spill" cannot then be properly taken care of. Critique. After the spill is cleaned up, but while m~nories of it are still fresh, those involved in the spill should sit down and discuss what went wrong (and what went right) during the operation, how things could be improved, and how better preparations could be made for future spills. An informal report should be made of the critique. Monitor. Periodically after the cleanup the site should be inspected, photographed, and surveyed for contaminants. In the case of winter spills, it may be necessary to take additional cleanup action at the time of spring breakup. The inspections may reveal the necessity to do certain rehabilitation work such as revegetation to avoid degradation of the site. O.K. For One Season? If the affected site has been stable for one year and shows signs that damaged vegetation is becoming restored, action on the case may be terminated. Stop spill. Shut off valves, transfer fuel from leaking vessels, repair leaks, take other appropriate.action to prevent spill extent from growing. What Oil? As shown on the diagram, different action is required for crude oil spills than for spills of distilled products. -9- 19. 20. Build sump and drain syst~. Natural drainage can be augmented with collection channels leading to a sump dug in the ice near the pad or in the pad itself, depending on how far the oil has spread. Skim. Oil collecting in the sumps can be r~oved using uumps, s~rs or Oil Mop equi~m~n, t. -10- DRILLING RIG DIESEL SYSTEM M -8A 25,000 GAL. DIESEL STORAGE M-2A M-8B 25,000 GAL.

Commissioner PROPOSED DEVELOP~ PLAN WEST SAK RIVER STATE NO. 11 (04-11-09) OPERATOR BP ALASKA EXPLORATION INC. October 1977 1. SITE LOCATION (SEE EXHIBIT "1") The proposed site of West Sak No. 11 (04-11-09) is the SE-l/4 of Section 4, Township llN, Range 9E, L%~iat Meridian being 2,450 feet from the south line and 2,078 feet from the east line of said Section 4. 2. SITE DESCRIPTION (Drawing No. A84D-B-4) The site on which the drilling pad will be constructed is 21 miles due west of "M" pad which is at the western end of the Prudhoe Bay oilfield. It is located between the Ugnuravik River to the east and Kalubik Creek to the west and is 12 miles south of the Arctic Ocean (Simpson Lagoon). The location is about 85 ft. above sea level and is covered by permanent tundra dotted with numerous shallow lakes. The Company considers the proposed location to be within the area served by the well-developed Prudhoe Bay field service facilities. Under normal winter conditions, the well site can be reached from the Prudhoe Bay road system after a forty-five-minute drive along 16 1/2 miles of gravel road, being constructed by ARCO and 6- 1/2 miles of snow road (between West Sak 7 and 11). Thus the well is exploratory only in the geologic sense. 3. SITE DRAINAGE (Drawing No. CC-0-0-034) The drill site pad surface and work area will have an elevation of at least three feet above the surrounding ground level with 1.5:1 side slopes. Facilities located on the pad surface which might contaminate will be surrounded by berms of gravel. The area around the rig slopes towards the well cellar which would collect any minor spills in that area. A reinforced plastic msmbrane will be placed beneath the entire drilling-rig structure. -1- Its surface will slope into a sealed steel cellar which will be permanently attached and sealed to the conductor pipe. Any oil or other contaminants which leak or is spilled from drilling rig equipment will drain into the cellar from which it can subsequently be pumped and transported to a disposal reserve pit. 4. AREA WILDLIFE Previous field experience and observations have revealed little wildlife in the area during the anticipated operational period (December - April). Construction and drilling operations for the proposed well will con, hence after freeze-up and be completed prior to spring thaw. Some wildlife which may be found in the general area during winter are the arctic fox, willow ptarmigan, snowy owl, and con~Dn raven. Other wildlife in the general area during the summer are caribou, wolf, wolverine, l~ing, bear, and waterfowl. It is not anticipated that winter operations will hinder the daily habits of any local wildlife. 5. AREA SETI~.~ No settlements or villages are in the vicinity of the proposed location. The location is approximately 23 miles from the Prudboe Bay Spine N~ad and is considered effectively within the extensively developed Prudhoe Bay field area, operated jointly by the applicant and Atlantic Richfield Ccmpany. At Deadhorse Airport, 39 miles to the SE, is located a hotel and public airport support facilities, year-round roads exist part way between Deadhorse and well site. Surface transportation to the drill site is possible only in the winter after construction of 6-1/2 miles of snow road. -2- 6. ACCESS ROADS Access roads are shown on Drawing No. A84D-B-4. Access to the drilling location will be from the Prudhoe Bay field Spine Road system by way of the ARCO West Sak gravel road and then by snow road. The Spine Road is a 30' wide, 5' thick gravel road with 1:3 side slopes. Spur roads are generally 20' in width but are otherwise to the same design. Ice roads over vegetated areas will be constructed by building up initial snow cover to a depth of 6", taking care not to cut or d_~_mage the tundra in any way. Water will then be applied by a flooding system such that ice not less than 1-1/2" thick is formed. Snow will be applied over the ice area to a minimum thickness of 6", and finally, by alternating blading and application of water, layers of snow and ice will be formed. The ice road will be maintained to this constructed standard by periodic alternate applications of snow and water. 7. SITE. PLAN (SF~ DRAWTNGS #A84D-Q-14, CC-0-0-34) The drill site will be constructed of gravel and consit of a single pad of sufficient size to accommodate the drilling rig, camp, and storage. The attached Drawing #A84D-Q-14 gives the approximate location of all contemplated facilities. The gravel placement Drawing No. CC-0-0-34 shows details of the pad construction. The drilling pad will consist of a minimum of 3 ft. of gravel and the foundation area for the rig machinery will be strengthened with timber piling. The tundra surface in the reserve pit will be excavated -3- to a depth of 2 ft. and the extracted material stockpiled for later replacement on the surface of the pit (See Section 17). This method cuts down on the amount of gravel required and improves the sealing qualities of the reserve pit walls. It also lowers the fluid level in the pit relative to the water table which serves to reduce the possibility of leaks developing. It has no adverse environmental affects compared to a reserve pit constructed on the tundra surface with higher gravel walls. 8. SOUN/E OF CONSTRUCTION MATERIALS (SEE DRAWING #A84D-B-4) Approximately 25,000 cubic yards of fill material will be required for the construction of the drilling pad. The gravel fill will be taken from the ARCO gravel stockpile in the S-l/2 of Sec. 8 TllN R10E and hauled directly to the drill pad site. Such gravel quantities are covered by existing gravel contract ~with the State of Alaska No. ADL-80500 purchased competitively in 1977. The area, together with the gravel haul and access routes are shown on Drawing No. A84D-B-4. Precise extraction areas have been surveyed and staked out by ARCO, and full details of extraction, haulage, and stockpiling procedures have been co~unicated to the State Division of Lands by Atlantic Richfield Company. BP Alaska, under terms of agre~nent with ARCO, will utilize gravel from the stockpile. An alternative source of gravel has been located at the cc~mon corner of Secs. 26, 27, 34, and 35, T12N R8E on the banks of the Kalubik Creek. If the ARCO gravel source is unavailable for any reason, application will be made to the State Division of Lands to utilize gravel from this alternate location. -4- 9. FUEL STORAGE (SEE DRAWING #A84D-Q-14) Fuel will be stored in steel tanks which will be surrounded by gravel and ice berms constructed for secondary containment. Once the gravel berm is constructed, it will be sprayed with water which when frozen will form an ice barrier. (Any fuel from a spill coming in contact with this berm ~ould be at ambient temperatures.) Inasmuch as the drilling program calls for completion prior to break-up, these ice-sealed gravel berms will be competent during the period of operations, based On past experience. Fuel- flow diagrams and transfer procedures, valving sequence and safety precautions are provided with the Spill Prevention Control and Countermeasure (SPCC) plan. All personnel working in the fuel handling area will be thoroughly trained in these procedures. 10. BI/J~-OUT PREVENTION PROGRAM EQUIPMENT This rig will be equipped with a 20" 2,000 psi W.P. Hydril annular diverter system installed on 100 ft. of 20" H-40 94# conductor pipe while drilling 17-1/2" surface hole to 2,200 ft. (See attachment: Diverter Syst~n Detail). In the unlikely event that low-pressure, low-volume surface gas is encountered, the well bore fluid can be diverted away from the drilling rig through a 10-3/4" line to the reserve pit and the gas allowed to vent to the atmosphere. After running and cementing 13-3/8" 729 N-80 surface casing at 2,200 ft., a blow-out prevention equi~nent (BOPE) consisting of three 13-5/8" 5,000 psi W.P. ram type preventers, a 13-5/8" 5,000 psi W.P. Hydril GK annular preventer, and a two-choke manifold will be installed. These preventers are powered by a 80-gal. Hydril accumulator system with both nitrogen and manual back-up. The BOPE will be thoroughly pressure tested for leaks using diesel fuel upon installation and at least weekly thereafter. Operational tests and crew drills will be conducted daily. -- 5 -- Primary well control will be maintained by over-balancing formation pressure with a column of drilling fluid. Automatic and manual monitoring equi~ent will be installed to detect any abnormal variation in the mud system and drilling parameters. A mud-logging unit manned by 'experienced personnel will be in continuous use while drilling and will monitor formation pressures, hydrocarbon shows, and loss or gain in the pits. In the event that the well kicks, the BOPE will be used to shut in the well in~ediately and confine the pressure within a closed system. The casing program is designed so any anticipated kick pressures can be shut in at the surface without breaking down the formation at the casing shoe. The Ccmpany representatives assigned to the drill site have had extensive training, including industry seminars, workshops, and nationally reCognized well-control courses at Louisiana State University and Okl~ University, together with actual experience in controlling and killing kicks. Such training is an on-going program of the Company. These personnel will be further supported by well trained drilling crews~ approved by the Company. Fluids resulting from a kick will be circulated out using the balanced bottom hole pressure method and the well will be restored to its normal operating condition. In the unlikely event that secondary control of the well is lost and premature well flow occurs, the company has at its disposal specially designed equipment and a blow-out contingency plan, experienced back-up personnel, a cementing unit at location at all times, and two rigs operating in the Prudhoe Bay area which can be utilized to mix mud or drill relief wells. -6- A description of the company's current blow out prevention training program together with a copy of its "Drilling Operations Blow Out Pre- vention Manual" is available for inspection by appointment. 11. SPILL PREVENTI°N CONTROL AND COUNTERMEASURE PLANS Spill Prevention Control and Countermeasure (SPCC) plans have been prepared for Rowan Rig No. 29, which is to drill this well. In addition, a site-specific SPCC plan has been prepared covering this location (attachment)'. These plans, which are available for review, describe spill prevention considerations, plus organization and procedures applicable in the event of a spill. Emphasis will be' given to training personnel, including contractor personnel in the avoidance of Spills. The Company employs a full-time environmental engineer who will monitor operations to ensure cc~pliance with environmental regulations and adherance to reconm~=_nded procedures. 12. DRILLING RIG CAMP (SEE DRAWING ~A84D-_O-14) The camp area on the drilling pad will be sufficient for a typical 50- man camp. The modular structures are provided for the safety, comfort, and convenience of the occupants. Water treatment and waste treatment and operating manuals covering the equipment in use with Rowan Rig No. 29 which will be drilling th_is well have not been attached because of their bulk but will be made available on request. We are advised this equitm~ent bas previously been approved by the State of Alaska, Department of Environmental Conservation. -7- 13. FOOD SERVICE The drilling contractor provides food service for the drilling camp. He is responsible for ensuring that all food is from an approved source, is properly refrigerated and stored on shelves off the floor. Cleanliness will be maintained and kitchen and dining ~facilities in compliance with applicable government regulations. 14. LOCATION OF WATER SUPPLY AND TREA~ (SEE DRAWING #A84D-B-4) Fresh water supplies for camp use, c~enting, rig boilers and drilling fluids will be obtained from three sources, tw~ of which are inland lakes and the third is an artificial reservoir which Atlantic Richfield Company is planning to construct at its proposed gravel source area in S-l/2 of Sec. 8 T10N RllE UM. Average daily usage from these sources will amount to 360 barrels per day and will be withdrawn using vacuum trucks or rolligons. Detailed plans of the propoSed ARCO reservoir have been sukmitted to the State by that company. Assuming the reservoir is built, water would be extracted from it for this well under an Atlantic Richfield water taking permit, which has been applied for. Such usage is covered by an agre~ent between BP Alaska, Inc., and Atlantic Richfield Company, Inc. The inland lake water sources are situated at E-l/2 of Sec. 1, TllN R7E and W-l/2 of Sec. 6, TllN R8E, and at W-1/2'Sec. 20 TllN R9E UM. The former lake is 8 ft. deep, and the latter is at least 6 ft. deep. ~k~ fish exist in these lakes, and they would be used until the water quality deteriorated to unacceptable levels. The poor quality is the result of both organic and inorganic impurities in the water being rejected as ice forms. These rejected impurities concentrate beneath the ice, and by spring the calcium -8- concentration can be 600 to 1,000 ppm. Treatment is necessary to remove most of this calcium. An application will be made to use this lake water. Camp water will be made portable using a water treatment facility enclosed in a skid-mounted, insulated steel building. A hydrochlorinator installed in the trea~t facility will inject chlorine into the raw water to control algae and bacteria and to precipitate manganese, iron, and hydrogen sulfide. A series of filtering processes will then remove sediments, iron, and manganese and also any taste, odor, and color. The water will then pass through a water softener where calcium and magnesium ions will be r~noved. Treated water will be stored in hot-water heaters and in storage tanks located throughout the camp. The backwash water from the treatment plant will be disposed of in an onshore pit (see below) utilized for the sewage treatment plant effluent. 15. METHODS OF HANDLING WASTE DISPOSAL Pollutants will not be permitted to accumulate at the drilling site. In general, burnable wastes will be disposed of in a Cc~tro incinerator on site, and other waste material will be transported away from the site on a frequent basis for disposal in an approved location on land. Garbage, noncombustible trash, ash from the incinerator, and other solid wastes will be transported to the waste disposal facility at Prudhoe Bay Pad "C". Sewage will be treated by the camp physical-chemical treatment unit, a 4,000 GPD MET-PRO waste-water treatment unit, series 14000. Effluent from this unit will be chlorinated prior to discharge and sludge will be incinerated on the pad. USed drilling fluid and drill cuttings will be discharged into the reserve pit at the drill site. Cuttings which are not contaminated -9- by oil or other harmful substances may be used in maintaining and stabilizing the gravel fill of the drilling pad. See the attached chart and flow diagram for a more detailed description of the above procedures which are intended to eliminate all intentional discharges on the pad. 16. AIR POLLUTION The incinerator and diesel-powered generators on the rig site (over 250 KV capacity) are permitted with the State Department of Environmental Conservation. No other equipment should be a source of air pollution. Should h~drocarbons be encountered and flow testing deemed necessary, an appropriate permit will first be obtained from the Department of Environmental Conservation. 17. PLANS FOR RESTORATION OF THE SURFACE Upon final completion of all drilling operations, this well will be plugged and abandoned in ccmpliance with all state regulations if ~cial quantities of oil and/or gas are not found. Abandonment will include setting mechanical plugs and/or cement plugs above all hydrocarbon producing formations and/or casing liner laps. The cement plug will be placed within the casing at the surface and a well cap installed with a marker post as per State Division of Oil and Gas regulations and equipment will be r~moved and the drill site thoroughly cleaned of any refuse. The stockpiled tundra material excavated during the construction of the reserve pit will be replaced on top of the surface of the frozen contents of the pit' This tw~-feet thick layer will insulated the pit contents from melting and will also function as a natural landscaping medium. - 10 - Should the well be capable of oil and/or gas production which will justify development wells and production facilities, it will be left in a suspended condition to allow re-entry into the well at a later date. This application is not intended to cover the establishment of production facilities should any be required. - 11 - *ALTERNATE, WATER SUPPLY' OTTER '.', P WEST SAK RIVER STATE ~.BP WEST S, RIVER STATE ATLANTIC RICHFIELD.
