The corrosion inhibitor is engineered to prevent water from entering the annular space and causing external corrosion that could result in a surface casing leak to atmosphere. The attached spreadsheet represents the well name, API and PTD numbers, top of cement depth prior to filling and volumes of corrosion inhibitor used in each conductor. As per previous agreement with the AOGCC, this letter and spreadsheet serve as notification that the treatments took place and meet the requirements of form 10 -404, Report of Sundry Operations.

These wells were drilled from one of the Niakuk exploratory islands used to deliniate the field. There were three wells abandoned last year on this island. We flew from Deadhorse by helicopter and landed on the island. I made a walk-around and found the island to be free of trash or debris. There was a slight depression in the island where the wells were abandoned earlier this year. This island will be allowed to erode naturally and should be visited occasionally to check on its progress. cc: BPX (Anchorage) SUMMARY: I made a location clearence inspection on BPX wells Niakuk #4, 5, & 6 in the Niakuk Field. i found no problems with this location Attachments: Photographs NON-CONFIDENTIAL TONY KNOWLE$, GOVERNOR ALASKA OIL AND GAS CONSERVATION COMMISSION August 15, 1996 3001 PORCUPINE DRIVE ANCHORAGE, ALASKA 99501-3192 PHONE: (907) 279-1433 FAX: (907) 276-7542 Land Department (MB 12-1) Pete Zseleczky Mgr.

Form 10-407 SUMMARY OF OPERATIONS PERMANENT ABANDONMENT SOHIO ALASKA PETROLEUM COMPANY (BP EXPLORATION ALASKA INC.) NIAKUK NO. 5 The Niakuk No. 5 welt was spudded on February 20, 1985, directionally drilled to 11,507' MD (10,643' TVD), suspended on April 18, 1985 and abandoned on April 15, 1996. The well was logged, cased and tested from several intervals between 10,016' MD' and 10,850' MD. At the conclusion of testing operations, the well was suspended by squeezing perforations and setting several downtxote plugs so as to effectively abandon the hydrocarbon bearing part of the hole. In addition, a shallow cement plug was set between 2,050' and 2,150' MD, the 13-3/8" X 9-5/8" annulus was Arctic Packed and the top 500' of the hole was displaced with diesel as freeze protection. The permanent abandonment work reported below consisted of: 1) displacing the diesel in the wellbore with kill weight brine; 2) setting surface c plugs in the wellbore and 13-3/8" X 9-5/8" casing annulus; 3) removal of wellhead and cellar; 4) severing all casing stings below the original mudline; and 5) backfilling, regrading and general location cleanup including the backhauling of solid and liquid wastes. Diagrams are attached showing the post abandonment condition of the well and the artificial gravel island on which it is located. (See Figures 1 and 2.) .' Niakuk No. 5 was permanently abandoned as part of a project xvhich abandoned all wells on Niakuk Island (Niakuk Nos. 4, 5 and 6) as well as the island itself. Separate AOGCC reports have been prepared for each well in the program. OPERATIONS SUMMARY Constructed ice road to Niakuk Island from East Dock. Mobilized equipment, materials and personnel to island from previous job (Northwest Milne No. 1). Steam thawed ice and gravel in well cellar and cleaned cellar of gravel backfill using super sucker. . Installed wellhouse and applied heat to wellhead. Checked pressures on wellbore and casing annulus. o Nippled up and tested BOPE. Displaced diesel freeze protection in wellbore with kill weight brine, taking returns to vacuum tank. 4. Set 170' (BGL) permafrost surface plug in 9-5/8" casing. (See Figure 3.) o Rigged down wellhead shelter a2~d hot air heater. Excavated to 15' below pad level, removed cellar. (See Figures 4, 5, and 6.) Hot tapped 13-3/8" casing to flush Arctic Pack out of annulus with brine before cutting casing strings. Cut casing strings and removed wellhead. (See Figures 7 and 8.) Niakuk No. 5 - Summary of Operations April, 1996 Page two . Displaced residual diesel in 13-3/8" X 9-5/8" annulus above solid Arctic Pack. Set surface annulus cement plug and topped off cement plug in 9-5/8" casing. All plugs inspected and approved by AOGCC inspectors Bobby Foster and Doug Amos. (See Figure 9.) . Trimmed up casing stubs to >4' below original mudline and welded steel plate over 13-3/8" and 9-5/8" casing stubs. (See Figure 10.) . Backfilled excavation, cleaned up and recontoured island surface. (See Figures 11 and 12.) Continued with abandonment work on Niakuk Nos. 4, and 6. Removed concrete groin from north side of Niakuk Island. . Final site cleanup and location clearance inspection is scheduled for summer 1996 after snow cover has melted. The job was completed with no lost time or OSHA reportable accidents, and no spills.

BACKGROUND AND SUMMARY OF PROPOSED WORK The Niakuk No. 5 well was spudded on February 20, 1985, directionally drilled to 11,507 fi. MD/TD (10,643 ft. TVD), and suspended on April 18, 1985. The well was logged, cased and drillstem tested from several intervals between 10,016 ft. and 10,850 ft. MD. At the conclusion of testing operations, several downhole plugs were set and perforations squeezed so as to effectively abandon the hydrocarbon bearing part of the hole. In addition, a shallow cement plug was set between 2,050 ft and 2,150 ft.; the 13-3/8" X 9-5/8" annulus was Arctic Packed; and the top 500 ft. of the well was displaced with diesel. The well was then suspended for future consideration as a Niakuk development or observation well. Niakuk No. 5 is no longer being considered for this purpose and the operator proposes to abandon the well in accordance with the program defined herein. Attachment I shows the current status of the Niakuk No. 5 well. The Niakuk No. 5 location is on a manmade gravel island in the Beaufort Sea approximately 1-1/2 miles north of Heald Point. Water depth in the vicinity of the island is 3 ft. The Niakuk No. 4 and No. 6 wells are also situated on this island. These wells are also scheduled for abandonment and are covered in separate submittals. In order to abandon the Niakuk No. 5 well and its location in accordance with current Alaska Oil and Gas Conservation Commission (AOGCC) regulations, the following tasks must be completed: 1. Displace diesel in the 9-5/8" casing with 10.3 ppg brine. 2. Set a 150 ft. surface cement plug in the 9-5/8" casing. o Set 150 ft., or maximum achievable length, if less than 150 ft., cement plug iii the 13-3/8" X 9-5/8" romulus. 4. Excavate and remove well cellar. o Cut off all casing strings a minimum of 4 ft. below original mudline (seafloor betbre artificial island was constructed), and install subsurface steel marker plate. 6. Backfill excavation and regrade island surface. Pickup any remaining debris on the location. NIAKUK NO. 5 1 The above work is required by 20 AAC 25.105 (i)(2)(k), 20 AAC 25.120, and 20 AAC 25.172 (c)(d). Attachment II presents a schedule for completing the abandonment of all Niakuk Island wells and island abandonment as a combined project. PROPOSED OPERATIONS PROGRAM , Obtain all required permits and regulatory approvals before starting job. Fairweather proposes to secure all permits for the project on behalf ofBPX. Anticipated permits include the following: · Application for Sundry Approvals, Form 10-403 (AOGCC); · Wastewater Disposal Permit; · Food Service Permit; · North Slope Borough Administrative Approval; and · Island Abandonment Plan Approval (DNR). , Mobilize all required personnel and equipment to the Niakuk No. 5 location on an as needed basis via CATCO units. The proposed personnel and equipment spread is as follows: Personnel: Working Supervisor (1) CATCO Operators (3) Mechanic (1) Welder (1) Cook (1) BOP/Wellhead Hand (1) EMT III/Environmental Tech (1) Equipment: CATCO Units as needed 200 ft. 3/4" Steel Pipe 200 ft. 1" Steel Pipe Nitrogen 966 Loader Cat 225 Backhoe 3,500 gal.

Check for pressure on 9-5/8" casing, and 13-3/8" X 9-5/8" annulus. Remainder of program assumes any pressure can be bled off. Remove master valve and tubing head adaptor. Nipple up and test 5,000 psi WP 7-1/16" BOP stack. BOP'swill consist of one set of blind/shear rams and an mmular preventer (see Attachment III). The BOP stack will be tested to 1,500 psi. Rig up mixing and pumping module. Rill with 1" open ended pipe to approximately 50 fl. Displace diesel in 9-5/8" casing with 10.3 ppg brine. Pump brine in small batches and allow brine and diesel to swap in wellbore. Monitor volumes pumped closely, in order to confirm when the fluid swap displacement is complete. When complete, POH with 1" pipe. Nipple down BOP stack. Rig.up mixing and pumping module. Using 1" open ended pipe, run in hole to 170 ft. below island surface. Push "poor boy" cement retainer (i.e. wad o1' cement sacks) in hole ahead of pipe. Mix and pump 170 fi. permafi'ost cement surface plug in 9-5/8" casing. Have plug witnessed by AOGCC representative. Excavate and remove well cellar box. Continue to excavate below cellar box to expose 20" conductor at a point approximately 5 ft. below original mudline. Cut and remove 20" conductor such that the remaining 20" conductor stub is approximately 4 ft. below original mudline. Break out cement from behind 20" conductor to expose 13-3/8" casing. Rig up safety line on wellhead to prevent wellhead from falling into excavated area as further cuts are made. NOTE: Conduct safety meeting prior to initiating Steps 6, 7, 8, and 9. Hot tap the 13-3/8" casing just above the 20" casing stub to drain Arctic Pack in 13-3/8" X 9-5/8" annulus. Rig up nitrogen supply to hot tap valve to provide nitrogen purge while cutting 13-3/8" casing. NOTE: Arctic Pack may be desiccated and will not easily drain from hot tap, but may be flammable nevertheless. NIAKUK NO. 5 3 o , 10. 11. 12. 13. 14. Cut and remove 13-3/8" casing window to expose 9-5/8" casing. Use caution when cutting 13-3/8" casing, since some compression may be present in 13-3/8" casing due to 9-5/8" casing string hanging in the wellhead. Cut rectangular windows (3" wide by 3' long) in an oppositely opposed radial fashion to gradually relieve compression. Use an extended reach torch for this work and expect the wellhead to drop several inches when 13-3/8" casing windows are removed. Cut 9-5/8" casing and remove wellhead for backhaul. After wellhead is removed, run in 13-3/8" X 9-5/8" annulus with 3/4" steel pipe to 150 fl. or to maximum achievable depth, if less than 150 ft. Notify AOGCC if 150 ft. depth cannot be achieved. Mix and set a permafrost cement surface plug in 13-3/8" X 9-5/8" annulus. Remember to get advance AOGCC approval for any surface annular plug that cmmot be set to the full 150 ft. length. Collect all displaced annular fluids in vacuum tank. Give AOGCC representative the opportunity to witness annular plug. Trim up casing stubs and weld a 30" X 30" X 1/2" steel marker plate identifying well on 20" conductor at approximately 4 ft. ,below original mudline. Backfill excavation to island grade, but leave small mound of gravel over excavation to allow for natural compaction after island thaws next summer. Attachment IV shows the post-abandomnent condition of the wellbore. Pick up any debris on location and move to next well in program or demob to Deadhorse, if Niakuk No. 5 is final well in program. File new Form 10-407 with AOGCC referencing the new P&A well status. Return to Niakuk No. 5 location the following sumlner to pick up any minor remaining debris exposed after snow melts, and to conduct a final location inspection with the AOGCC and DNR. WASTE DISPOSAL AND RESPONSIBILITIES FOR WASTE NIAKUK NO. 5 All liquid wastes recovered in the abandonment program will be transported in secure tanks to CATCO's yard in Deadhorse. The recovery and transportation of these wastes will be accomplished by Fairweather in a manner satisfactory to BPX. After transport to CATCO's yard, the wastes will be available for the BPX contract hauler to transport the wastes to an injection facility as directed. BPX will be responsible for final disposal arrangements (injection). Fairweather will facilitate final disposal, if requested. . Solid waste (i.e., cellar box, wellhead, etc.) will be transportcd to the North Slope Borough Solid Waste Disposal Site for disposal. This will be accomplished by Fairweather. o In the event that any hydrocarbon contaminated gravel and soil is identified during excavation, the materials will be segregated and staged on location. Sampling, transport and disposal of such materials will be at the direction of BPX and costs for such services will be in addition to the fixed price well abandonment bid. REPORTING AND BPX OVERSIGHT BPX will receive daily progress reports faxed to the Anchorage BPX ol'ficc and to the designated recipient on the North Slope during the term of the project. During any periods when a BPX representative is not on site, the faxed reports will be followed up by a phone call to the designated BPX contact in Anchorage or on the North Slope. o The amount of direct BPX oversight of field operations is entirely at the discrction of BPX. Transportation and camp space will be provided for the BPX representative.

Tax'lo: BP Exploration ~A!aska) Inc. P. O. Box !966i2 Anchorage. AK 99519-6612 Dear Mr. Taylor: Re' BP Exmoration {Alaska)Inc. inactive Drilling Waste Disposal Faciiiw Closures - Numerous Inactive Sites The Alaska Departrnant of Environmental Conservation tADEC) has received and completed its review of ,,'our August 9. 1993 letter, with enclosures. -= ' o **quesnn= a2proval for closure of BP Exploration (,Alaska} Inc. Drilling Waste Disposal Facilities on the North Slope. These sites have been reviewed in accordance with the ADEC 'Interim Site Assessment Guidance for ~nactive Drilling Waste Sites. June !991. This correspondence describes our review proceaures, puts fcrw~'ard the deaartment's findings, and takes action on the requests. Currently, the second draft of Alaska's new Solid Waste Regulations. 18.AAC 60. are under review, and this second draft contains a chapter on Inactive Reserve Pit closures. The closure criteria in tttis proposed re~m.tlation parallels the closure criteria in the 1991 Guidance Document. Closure under the 199! Guidance Document should constitute closure under the proposed Solid Waste Re~m.tlations if they are adopted as current drafted. The Review Procedure The cmaiitative risk screening procedure required in the above referenced document determines whether a site presents negligible levels of risk. or if it is a significant risk generator. A decision scheme is then employed to establish ~ 1') whether or not there is a Mr. Steven D. Taylor Januar,,, 12. 1995 BPXA Inactive Drilling Waste Disposal Facility Closure ApPrOval basis of concern, and (25 whether or not a waste site is likely to present significant risk to human or environmental receptors. The first step in this screening criteria is establishing a basis of concern: "If the waste site has released contaminants or there are mechanism for potential releases and there are receptors nearby, then. there may be cause for concern, and the waste site should be studied further." and "If there is no release of contamination or no me:hanisms for potential releases and there are no recemors nearbv, then there is not a basis for concern and the waste site shouid be considered cioseci." The criteria that are measured at a waste site to satisfy the above logical arguments are: Evidence of release of chemical contamination at the waste site in excess of Alaska Water Quality Standards for one er more tarzet :.omr~ounds. or Mechanism for potential release, and Proximity of the waste site to biotomcai receators. If either of the first two criteria and the last criteria are met. there is a baSis for concern, and before proceeding with Step 2. a corrective action plan shall be prepared for the site which shall identi~, alternative wavs to correct or mitigate the basis of concern, prevent its recurrence, and select a preferred approach. Corrective action alternatives shall be described at a conceptual level, and the selection of a preferred approach shall be based on balancing protectiveness with implementability and cost-effectiveness. The second step determines whether contamination at a waste site present a risk to receptors that is sigrdficam. If risk is found not to be significant, it is considered to be "negligible.'' The finding o.._~r~sjgnificant risk is based on the i'ikelihood of exposure and the likel~hO'od of adverse conSequences of exposure' "For risk to be considered significant, the receptors must be vulnerable to exposure, and the consequences of exposure must be 'adverse' to human or ammal health or the environment." and. conversely, "If exposure is unlikely or the consequences of exposure are not 'adverse,' then the risk is negligible. Mr. Steven D. Tavtor January i2. 1995 BPXA inactive Drilling Waste Disposal Facility Closure Approval If risk at a waste site is si_~nficiant, then corrective action should be taken. The criteria that are e;'aluated at a waste site to satisfy tt-,e logical arTaments above are exposure criteria and consequence criteria. Exposure Criteria: Receptor exposure is considered to be likely when: Contaminant reiease mechanisms are ~ud~e~ significant, or Containment migration is judged significant, c.r One or more contaminants are envirorumentally persistent. If exoosure is founci to be uniikeiv, a findin2 of ne2ii2ible risk is made on the basis of absence of a likely exposure item and the action oian is evaiuated under the Impact/Benefit Evaluation step. The pu~ose of this step is to dete,,':mine whether the benefits of taking a corrective action would be greater than the impacts of taking such a corrective action. If an',' one of the exposure criteria are met. a finding is made that exposure is likely. screening then continues to evaluate Consequence Criteria. Further Consequence Criteria: Adverse consequences of exposure to contaminants from reserve pits are considered to be likely when: {.a) The duration or frequency of exposure is sufficient to cause adverse health and environmental effects. This is evaluated by revie,xing human and wildlife use patterns at a given waste site. waste site accessibility, and ground and surface water uses. and either; (b) The quantity or concentration of one or more contaminants exceeds pertinent federal or state water quality criteria or standards protecting health and/or the environment. Measured contaminant concentrations in the water will be compared with health and environmental standards and criteria for each target contaminant, to identif-3,' exceedances. When only human populations are at risk. health criteria are used. When only populations at risk are nonhuman/e.o fish. wildlife vetetation) =.. . _ . =-'ironmental criteria and standards are used. or: (c) One or more contaminants exhibit high acute toxicin'. The NIOSH toxicity rating system {NIOSH t974¢ will be used to identify contaminants highly toxic to mammals. This Mr. Steven D. Taylor January' t" ' ~995 BPXA Inactive Drilling Waste Disposal Facility Closure Approval information will be used to determine whether a target comvound exhibits acute high toxici~,. If the duration and frequency of exposure is insufficient to cause adverse effects, there is no need to evaluate the other t:vo consequence criteria, and a finding of negligible risk is made. If the duration and frequency term is sufficient, but neither of the other two consequence criteria are met. a finding of negligible risk is made. The action plan is then evaluated under the Impact:Benefit Evaluation stev. If the duration and freouencv or' exposure is determined to be sufficient to cause adverse effects and eider of the other two consec:uence criteria are satisfied, then a finding is made that adverse consequences are likely, and the risk at a waste site is said to be significant. If the screening indicates that risk is significant, then the responsible part3.' shall proceed with implementations of corrective actions.

Commission Anchor~g suspended Wells. ReQuest to retain suspension status The following wells are listed as suspended by the AOGCC under 20 AAC 25.110. These wells are requested to remain suspended for the reason(s) as indicated. Site inspections should be conducted as soon as possible. MPA-01; 029-20376-00 79-/¢04 Potential recompletion in the Kuparuk C and/or B sand as a water injector. Decision hinges on 1994/95 development drilling results (E-13)in this area. MPB-02; 029-20662-00 81-/¢(142 This well is scheduled for initial completion in the Schrader Bluff late this year or early next year. MPA-03; 029-20891-00 83-~¢001 Future utility as a Schrader Bluff producer with producing utility when sudace infrastructure is installed on A pad. MPN-01 B; 029-21053-02 84-0013 N-01B is a usable well in the Schrader Bluff, with producing utility when surface infrastructure is installed on N pad. The well should be retained in a suspended status until that time. MPC-16; 029-21364-00 85-O 110 C-16 has recompletion potential in the Kuparuk "C" sand and/or the Schrader Bluff horizons. Although additional evaluation must be performed to quantify reserves and production potential, C-16 is believed to be a viable workover and/or sidetrack candidate. NWM#1; 029-22231-00 91-0145 Northwest Milne #1 should remain suspended until the Northwest Milne Point development is better defined. The wellbore is strategically located on a gravel island and may possess utility in either production or injection operations. DNR recently certified this well as capable of production. No Point #1;029-22450-00 94-0027 No Point #1 will.be utilized in the upcoming F- Pad development. Expectations are to complete the Kuparuk "A" zone and commence production 4Q95. Niakuk #4, 029-21217-00 84-0200 Niakuk #4 is requested to remain suspended until the viability of the well for monitoring is defined. Niakuk #5, 029-21290-00 85-0027 Niakuk #5 should remain suspended for observation purposes at this time. Sag Delta #33-12-16, 029-20176-00 75-0058 Area being drained by 1994 Alapah well NK-26 (HAW). Potential use as a monitor well for this new reservoir Would have to truck oil across winter ice road if resume production Produced 186 MBO in 1985 2 month production' test. Sag Delta #5, 029-20527-00 80-0129 Area being drained by L5-26 (high gas well), L5-28, and L5-36 from south to west. Well tests indicated fairly tight, but productive rock; perhaps inadequate stimulation? Costs prohibitive for eventual tie-in to L5 (? via Heald Point). Potential for gas cap monitor well Sag Delta 31-11-16, 029-20011-00 69-0014 Area being drained by L4-36, 80 Acre offset to NW. Potential for service well (water injection?) Well is capable of production, but most Lisburne in water leg and costs likely prohibitive for tie-in to L4. Sag Delta #2A, 029-20234-01 77-O069 South of Sag Delta #1, in water leg of Alapah oil accumulation in NK-26 well. Remote potential for pressure monitoring of Alapah off'take and the effect on the Alapah aquifer; though, costs would likely be prohibitive. Sag Delta #8, 029-20519o00 80-0121 Z-32A, 029-21924-01 93-O 113 S-10A, 029-20765-01 91-0123 Sag Delta #8 should remain suspended until the development plan for the area is better defined. This well may possess utility for production or as an observation well. Z-32 was shut in due to high water production in 1992. In 1993 it was sidetracked to a new location. The oil column at the new location was less than prognosed and was not considered economic and the well was suspended. There is oil in the area that can be reached as a new sidetrack from this well. A specific location has not yet been identified, but we wish to retain this wellbore for a future sidetrack. S-10 was sidetracked in 1992. Drilling difficulties were encountered while drilling through a fault in the Kingiak and the well was suspended. There is oil in the area that can be reached as a new sidetrack from this well. A specific location has not yet been identified, but we wish to retain this wellbore for a future sidetrack. The West Sak formation, a non unitized formation in the PBU license area, is reachable from this wellbore. Work in ongoing on a facility sharing agreement. In the case that a satisfactory agreement is reached, this wellbore could be used to access oil in this formation. Y-22A, 029-21558-01 88-0115 Y-22 was sidetracked in 1988. The sidetrack.was suspended due to drilling difficulties. There is oil in the region that can be reached as a new sidetrack from this well. A location has not been worked on but we wish to retain this wellbore for a future sidetrack. U-01, 029-22244-00 92-0011 PR 33-12-13, 029-20047-00 69-0104 There is oil in the area that can be reached as a new sidetrack from this well. A specific location has not yet been identified, but we wish to retain this wellbore for a future sidetrack. The well penetrates The West Sak and Ugnu formations in the aquifer. Work in ongoing on a facility sharing agreement with subsequent appraisal of the formations. This well could be used to test the aquifer properties. These wells are listed as suspended, action items are detailed. Ak Island ¢1,289-20018-00 81-0119 Alaska Island ¢1 was abandoned in 1988. The completion notice has been refiled with AOGCC on 9/15/94. The site is ready for inspection (priority 1 ). Niakuk ¢1A, 029-20156-01 76-0028 Niakuk ¢1A was abandoned in 1991. A sundry application requesting status change was filed with AOGCC 9/20/94. A completion notice will follow when the sundry application is approved. The site is ready for inspection (priority 1). Niakuk ¢2A, 029-20180-01 76-0079 Niakuk ¢2A was abandoned in 1991. A sundry application requesting status change was filed with AOGCC 9/20/94. A completion notice will follow when the sundry application is approved. The site is ready for inspection (priority 1). PBU H-01, 029-20099-00 71-0015 The well was drilled in 1971 and hit a down thrown fault block with only 20ft of oil bearing Ivishak. This was not economic at the time. It was left suspended without tubing. Recent success in fraccing the Sag formation indicated that it might be an economic well. A rig workover was completed in April 1994 and the well was put on production 9/94. It is not necessary to inspect this site. Kemik Unit #1,223-20006-00 70-0060 Kemik Unit #1 is scheduled to be abandoned in the near future. Abandonment planning is now in progress, Site inspection will not be necessary at this time most likely should be scheduled for Spring of 1995. P2-59, 029-22096-00 90-0140 Arco Alaska Inc. is the operator of this well, they will be addressing the question of suspension. Sag Delta ¢3, 029-20233-00 79-0080 Well plugged and abandoned March, 1991. Well completion notice will be refiled with the Commission.

This unleased land was offered for lease in Federal OCS Sale 124 which was held on June 25, 1991.

Obeney: In your March~:]~88 letter~~, requested that tile confidentiality of 'tile data from th~~t~ #4 an~~lls be extended beyond tile original extension of "until 90 days after (federal) Sale 97." The confidentiality period for the data from these wells was originally extended on February 2, 1987. At that time, tile nearby unleased land, Block 608 (protraction diagram NR6-3, Beechy Pt.) was scheduled to be offered for lease in Sale 97. Block 608, portions of which are in dispute between the State of Alaska and the United States, was not offered for lease in Sale 97 and, therefore, remains unleased. Block 608 will probably be offered for lease again in the next federal Beaufort Sea lease sale (Sale 124), currently scheduled for February 1991. If tile state receives title to tile disputed portions of Block 608, it is possible that those lands may be offered earlier than February 1991 in a state lease sale. Following your request for a further extension of confidentiality, data review, and in recognition of tile fact that Block 608 remains unleased, I agree to grant a further extension of. confidentiality for tile data from the Standard Niakuk #4 and #5 wells until the acreage ill Block 608 is offered for lease. By copy of tills letter I am asking the Alaska Oil and Gas Conservation Commission (AOGCC) to extend the period of confidentiality for data from the.

Data from these wells are scheduled to be released on March 19, 1987 and May 18, 1987, respectively. The Ntakuk #4 and Ntakuk #5 wells are situated approximately 2.5 and 3 miles, respectively, from unleased land described in the federal protraction system as Block 608 (Protraction Diagram Beechy Pt.

It should be recognized that this Notice does not indtca'te a preliminary decision to lease in the area described below. . Information submitted in response to this Call will be used for. several purposes. First, responses will be used to identify the areas of potential for oll and gas development. Second, conTnents on possible environmental effects and use conflicts will be used in the analysis of environmental conditions in and near the Call area. Together these two considerations will allow a preliminary determination of the potential advantages and disadvantages of oil and gas exploration and develo~nent to the region and the Nation. Thus, it m~y be possible to make key decisions in connection with the next step in the planning process--Area Identification--to resolve conflicts-by deleting areas where there is sufficient information to Justify that action. However, the Area Identification represents only a preliminary step to select the area to be analyzed in the environmental impact statement (BIS). The Area Identifi- cation is scheduled for January 1985. A third purpose for this Notice is to use the con~mnts coiled:ed to initiate scoping of the EIS, which will include public meetings, and to identify and analyze alternatives to the proposed action. A Notice of Intent is located later in this document. Fourth, ¢oflmmnts may be used in developing lease ter~s and conditions'to assure safe offshore operattoos. Fifth, conmmnts may be Used in understanding and considering ways to avoid or mitigate potential conflicts between offshore oil and gas activities and the Alaska Coastal Management Program (AC~P).

The deferred area was comprised, in part, of blocks west of Point Barrow which were removed to reduce the potential for conflict with subsistence resources. Blocks within m ZO-mlle radius of Point Barrow were deferred to further reduce the potential for conflict with subsistence activities and resources. Covenanters are asked to reexamine the areas deferred at Sale 87 and to provide their views as to whether these areas should be given further consideration or should be deleted from Sale 97 at the Area Identification stage. A~y new information as to resource potential, technology, subsistence use and resources, ice, etc., relevant to the area deferred it Sale 87 would be most useful. The DOI has held three Federal offshore oil and gas lease sales in the Beaufort Sea/Otaptr Field area. ?he first Federal offshore sale in the Beaufort Sea was conducted jointly with the State of Al&ski. This sale, the Joint' Federal/State Beaufort Sea 0tl lnd G~s Lease Sale (BF), was held December ~, ~979, and offered a combined'total of approximately 5~4,~02 tcres of State and Federal offshore lands.

Box 6612 Anchorage, AK 99502-0612 Re: Extension of Susu~ended Status -Niakuk No. 1-A Niakuk No. 2-A Niakuk No. 4 Niakuk No. 5 Sag Delta No. 9 Sag Delta No. 10 Telecopy No. (907) 276-7542 Dear Mr. Allan: A review of our records shows that the above referenced wells are suspended. 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(d) states: "Each well drilled from a beach or from an artificially constructed island or a shifting natural island must be abandoned or suspended before removal of the drilling unit from the site unless completed as an oil, gas or service well..., and plans for'maintaining the integrity of the well site are approved by the Commission." In compliance with Section 172(c) of the regulations, "[f]or a well abandoned from an artificial gravel island or a shifting natural island, the well site must be cleared within one year following abandonment, or before the time'that the operator ceases to conduct activities necessary to ensure the integrity of the well site .... " Section 105(m) provides the means for obtaining "...a variance from the requirements of this section if the variance equally effects proper plugging of the well and will not allow the movement of fluid into sources of hydrocarbons or freshwater." Mr. R. S. Allan August 1, 1986 Page 2 We are, therefore, requesting that you submit Form 10-403, Application for Sundry Approval, for a one-year extension of suspended status for the above referenced wells together with justification for keeping the wells in suspended status.

The retainer (E-Z Drill) was set at 9,950 feet, at 5:45 am. The retainer was unstung w/50,000 lbs of pull. At 6:30 am 3.38 bbls. of 15.8 lb Class "G" was placed on top of retainer to 9,860 feet approximately 90 foot plug inside the 7" liner. At 8:10 a.m. the next plug was a balance plug placed from 9,560' up to 9,413', which I witnessed tag at 4:30 pm, which was at 90' cement above 7" liner. ri! 15, 1985: There was a leak in the 9 5/8" casing jusn c~in~a~. Sohio's program was to cut 9 5/8" casing at 1,920', circulate Arctic pack out and polish the 9 5/8" to run a Bash Ross tie back patch. The first patch did not hold, 9 5/8" was pulled out of hole. Tuesday, April 16, 1985: A new reamer was run in hole with Tri ~~ ~ork, the reaming was finished at 3:30 pm. The patch was installed on the 9 5/8" casing and was run in hole and set over the stub of the 9 5/8 casing that was cut at 1,920'. The slips went do%.n~ to 1,925' outside of stub and was set at 1,924'. There was 265,000 pounds of weight picked up on slips of patch setting time 9:30 pm. At 15 minute pressure test was put inside 9 5/8" casing at 1,180 psig and no leak off. The string weight was I10,000 pounds and was slacked off to 150,000 from 265,000 pounds for above test. W__e_dnes~ril i7,__198_5: Run into hole drilled out DV plugs, tested 9 5/8" DV collar and casing patch to 2,000 psig for 10 minutes, no leak off. Then pulled out of hole. C. v. Cba~~n -2- ~April 29, i985 Thirty two stands of drill pipe was run into hole open ended and a balance plug was placed with 41 cu. ft., 43 sacks Perm "C" cement 15.0 ppg. The balance plug was placed 2,100' to 2,050' I witnessed the top of the cement tagged at 2,050' at ll:i0 pm, April 17, 1985. I received suspension program and schematic of bottom plugs to be attached to this report. In summary, I witnessed the successful suspension of Niakuk No. 5 for Sohio on AUDI Rig 2.

Lay a cement plug across the top of the 7" liner at 9,504' BKB extending 50' below the liner top and 100' above the liner top. 4. Repair leak in 9 5/8" casing by cutting casing at +1800' BKB, removing damaged pipe and tieing back to surface using a casing patch run on 9 5/8T; casing, the 9 5/8" x 13 3/8" annulus will be cemented for 200'-300' above the patch and freeze protected to surface. 5. If patching operations on the 9 5/8" casing are sucessful a cement plug will be laid from 2100' to 2000' and the well suspended for re-entry next year when a completion will be run and further testing carried out.

The perfs are below retainer at 10,810 to 10,850 feet. The retainer (E-Z Drill) was stabbed into with approximately 20,000 pounds of weight, dropped off of string, on top of retainer. The injection rate buildup was 2,700 psi and broke down to 2,300 psi at 3.5 bbls. a min. There was an attempt to squeeze 25 cubic feet of Class "G" cement into the perforations below retainer at 9:15 pm, but approximately one barrel was all the formation would take.

Haliburton unstung from retainer and laid 111 feet of cement on top of retainer inside the 7" casing, i left the location to another job at 10:30 pm. in summary, I witnessed approximately one barrel of cement squeezed into the perforations on Sohio Niakuk No. 5 well and 111 feet Class "G" cement placed on top of retainer set at 10,805 feet. 02-00IA(Rev. 10/79) , -IIO ALASKA PETROLEUM COM POUCH 6-612 ANCHORAGE, ALASKA 99502-0612 NY ANCHORAGE OFFICE: 3111 "C" STREET · ANCHORAGE, ALASKA 99502-0612 · (907) 561-5111 TO: State of Alaska ORIGINATOR: Julie A.

Btmhole Loc. 4312'SNL, 2456'EWL, Sec. 30, T12N, R16E, UPM. Dear Mr. Reiley : Enclosed is the approved application for permit to drill the above referenced well. Below 2700 feet a complete set of drill cuttings samples is required consisting of no less than four tablespoons of washed and dried cuttings for each 10, 20, or 30 foot interval of hole drilled, whichever interval is determined for sample collection. If coring is conducted, a brief description of each core and a one cubic inch size chip from each foot of recovered core is required. Below 2700 feet a complete mud log is required. A continuous directional survey is required as per P0 AAC 25.050(b)(5). If available, a tape containing the digitized log information shall be submitted on all logs for copying except experimental logs, velocity surveys and dipmeter surveys. Many rivers in Alaska and their drainage systems have been classified as important for the spawning or migration of anadromous fish. Operations in these areas are subject to AS 16.05.870 and the regulations promulgated thereunder (Title 5, Alaska Administrative Code). Prior to commencing operations you may be contacted by the Habitat Coordinator's Office, Department of Fish. and Game. Pollution of an;y waters of the State is prohibited by AS 46, Chapter 3, Article 7 and the regulations promulgated thereunder (Title 18, Alaska Administrative Code, Chapter 70) and by the Federal Water Pollution Control Act, as amended. Prior to Mr. R. H. Reiley Niakuk No. 5 -2- February 19, 1785 commencing operations you may be contacted by a representative of the Department of Environmental Conservation. To aid us in scheduling field work, please notify this office 24 hours prior to commencing installation of the blowout prevention equipment so that a representative of the Commission may be present to witness testing of the equipment before the surface casing shoe is drilled. Where a diverter system is required, please also notify this office 24 hours pr~.or to commencing equipment installation so that the Commission may witness testing before drilling below the shoe of the conductor pipe. In the event of suspension or abandonment, please give this office adequate advance notification so that we may have a witness present. · VD~y truly yours, ~ C. V.
