The well was shut in due to high GOR in 1998. The well is planned to be sidetracked to a new bottom hole location as a conventional producer targ~eting the Kuparuk reservoir. The sidetrack is currently scheduled for Doyon 14 beginning around March 25"', after the completion of NK-08A. The pre-rig work for this sidetrack is planned to begin as soon as the attached Application for Sundry is approved. Pre-Riq Work: * Notify the field AOGCC representative with intent to plug and abandon * RU slickline and install dummy valves in all GLMs. RIH with CTU, through tubing, to top of fill in 7 5/8" casing. Perform a cement P&A using 15.8 ppg class 'G' cement with adequate cement volume to fill the 7 5/8" casing from top of fill to a minimum of 100' into the 4 Y2" tubing. Squeeze 5 additional bbls into the perforations. Rig up slickline, tag and document top of cement and drift tubing for upcoming tubing cut. Liquid pack the tubing and 7-5/8" x 4-1/2" annulus to surface. Test the integrity of the cement plug and casing by simultaneously pressure testing both the tubing and annulus to 3500 psi for 30 minutes. Increase tubing pressure prior to the 7-5/8" annulus to avoid possibility of tubing collapse. Cut the 4 ¼", 12.6#, tubing at approximately 8,400' MD. Displace the well to clean seawater by circulating down tubing through the tubing cut. Continue to circulate until clean sea water returns to surface. Freeze protect top 2200' MD with diesel. Pressure test the casing pack off for 30 minutes. If 7 5/8" casing was set on emergency slips, test the 7 5/8" pack off to 3,832 psi, which is 80% of the casing collapse pressure. If the 7 5/8" casing was landed on a mandrel hanger, test the pack off to 5,000 psi. Test the tubing hanger seals to 5000 psi for 30 minutes. Bleed tubing and annuli pressures to zero. Set a BPV in the tubing hanger and test from below to 1000 psi. Secure well. Remove the well house and flowlines. If necessary, level the pad. Please provide total well preparation cost on the handover form. Rig 1. 2. 3. 4. 5. 6. 7. Operations: MIRU Doyon 14. Circulate out freeze protection and displace well to seawater. Set TWC & test from below. Nipple down tree. Nipple up and test BOPE. Pull and lay down 4-1/2" tubing from E-line cut and above. MU 7-5/8" window milling assembly and RIH to top of tubing stub. POOH. RU E-line and set CIBP at -8,087' MD. To avoid cutting a casing collar, set the BP 2' - 3' above a collar. RIH with 7-5/8" Baker bottom-trip anchor whipstock assembly. Orient whipstock at 85° RT of HS and set. Mill window in 7-5/8" casing. Perform FIT test to 13.0 ppg. POOH RIH with 6 3/4" drilling assembly to whipstock. Kick-off and drill to THRZ @ -55 degrees inclination. Continue to drill through Kuparak Sand to Top Kingak holding angle at -55 degrees inclination. 9. Spot liner running pill. POOH w/DP. Run and cement a 4 Y2", 12.6 # p~'oduction liner. Displace cement w/viscosified brine perf pill followed by brine. Release from liner and circulate out excess cement and displace well to brine. POOH. After cement has gained compressive strength, test the casing and liner from the landing collar to surface to 3000 psi for 30 minutes 10. Install 4-1/2", 12.6# L80 tubing completion. 11. Drop ball/rod & set packer and test the tubing to 3500 psi and annulus to 3500 psi for 30 minutes. 12. Nipple down the BOPE. Nipple up and test the tree to 5000 psi. 13. Freeze protect the well to -100' below the first GLM and secure the well. 14. Rig down and move off. Post-Riq Work: 1. MIRU slickline. Pull the ball and rod / RHC plug from below the new production packer, Install gas lift valves, 2. Perforate with Eline.

BOX 107~34 ANCHORAGE. ALASKA 99510-7034 PHONE: (907) 762-2553 (907) 762-2547 'December 27, 1994 BP Exploration (Alaska) Inc. 900 East Benson Blvd. P.O. Box 196612 Anchorage, Alaska 99519-5111 Attention: A. N. Bolea Asset Manager, Greater Pt. Mclntyre Area Subject: Prudhoe Bay Unit Niakuk Well N-19 Tract Operations Dear Mr. Bolea: The Division of'Oil and Gas has reviewed BPX's request to produce the Niakuk N-19 well as a Tract Operation (T12N - R15E, U.M., Sec. 36: NE/4) within the Prudhoe Bay Unit (PBU), dated December 14, 1994. The division approves production of the well as a Tract Operation in the PBU subject to the following terms and conditions: 1) All production from the well shall be allocated to the lease, ADL 34630. On the monthly royalty report, BPX, as the sole owner of ADL 34630, shall individually account for the production from the well. 2) The currently approved well test allocation methodology for measuring and allocating gas and hydrocarbon liquids among all the participating areas that share the Lisburne Production Center (LPC) is acceptable and satisfactory for royalty purposes and for allocating gas and hydrocarbon liquids among the PAs and this Tract Operation that will share the LPC facilities. As with the currently approved allocation methodology, the division reserves the right to review and revise, if necessary, the tract well test allocations to insure compliance with the approved methodology. recycled paper Mr. A. N. Bolea December 27, 1994 Page 2 ? 3) A minimum of two well tests per month will be performed to determine the monthly production from the N-19 Well. The individual well test data for each month of tract production, and the monthly production (oil, gas and water) allocated to the tract should be separately reported as part of the monthly Greater Pt. Mclntyre Area allocated production report submitted to the division. 4) A gas disposition and reserves debit report that accounts for the gas produced from each participating area sharing the LPC and all utilization of that gas (fuel, sales, reinjection, etc.) is submitted to the Division with the rno, d'dy production allocation report. Instead of separately accounting for the N-19 Tract Operation gas within the monthly gas reserves and debit report, the Division will permit the gas produced and allocated to the N-19 Well to be part of the monthly Niakuk Participating Area gas reserves and debit report. The intent is to simplify the monthly gas volume accounting report during the approval period of the N-19 Tract Operation. 5) Any deductions from the state's royalty share of oil produced from the N-19 Tract Operation is governed by the 1980 Prudhoe Bay Settlement Agreement. Whether the state bears any deductions of any kind whatsoever (whether called allowances, deductions or fees) for the state's royalty share of "NGLs" and dry gas allocated to the N-19 Tract Operation, and if so, what those deductions may be, are part of the Severed Issues in the ANS Royalty Litigation. These deductions, if any, are subject to the final resolution of this litigation. 6) Regarding the production allocated from the N-19 Tract Operation and the state's taking of any royalty oil in-kind from the Tract Operation, it continues to be the state's position that it has only nominated the taking of royalty oil in kind and has never nominated gas for in-kind taking. 7) Approval of the N-19 Tract Operation is given for a period of twelve months beginning January 1, 1995 or until submittal and approval of an application for expansion of the Niakuk Participating Area (NPA), whichever is sooner. A status report for the activities conducted under this tract operation approval shall be filed with the division every four months. 8) Should the NPA be expanded to include all or portions of the Tract Operation acreage, no reallocation of the royalty share of production allocated to the lease prior to the effective date of the revision of the participating area will be permitted.

Niakuk 19 October 3, 1994 IT APPEARING THAT: . BP Exploration (Alaska), Inc. submitted an application dated September 14, 1994 requesting exception to 20 AAC 25.055(a)(1) to a. llow drilling the BP Niakuk 19 exploratory oil well to a location that is closer than 500 feet to a drilling unit boundary. . Notice of opportunity for public hearing was published in the Anchorage Daily News on September 16, 1994 pursuant to 20 AAC 25.540. 3. No protests to the application were received. FINDINGS: The BP Niakuk 19 well as proposed will be a deviated hole drilled from a surface location 3846' from the north line and 815' from the east line (FEL) of Section 36, T12N, R15E, Umiat Meridian (UM) to a proposed bottom-hole location of 35' from the south line and 951' FEL of Section 25, T12N, R15E, UM. 2 BP Exploration (Alaska) Inc. is the sole owner of all offsetting spacing units. 3. An exception to 20 AAC 25.055(a)(1) is necessary to allow drilling of this well. CONCLUSION: Granting a spacing exception to allow drilling of the BP Niakuk 19 well as proposed will not result in waste nor jeopardize correlative fights. Conservation Or6~.'' No. 339 October 3, 1994 Page 2 NOW; THEREFORE, IT IS ORDERED: BP Exploration (Alaska), Inc.'s application for exception to 20 AAC 25.055 for the purpose of drilling the Niakuk 19 well is approved as proposed.

Babcock, Commissioner Alaska Oil and Gas Conservation Commission AS 31.05.080 provides that within 20 days after receipt of written notice of the entry of an order, a person affected by it may file with the Co~m~fission an application for reheating. A request for rehearing must be received by 4:30 PM on the 23rd day following the date of the order, or next working day if a holiday or weekend, to be timely filed. The Conmfission shall grant or refuse the application in whole or in part within 10 days. The Conunission can refuse an application by not acting on it within the 10-day period. An affected person has 30 days from the date the Conmfission refuses the application or mails (or othemSse distributes) an order upon rehearing, both being the final order of the Cmmnission, to appeal the decision to Superior Court. Where a request for rehearing is denied by nonaction of the Conmfission, the 30-day period for appeal to Superior Court runs from the date on which the request is dee~ned denied (i.e., 10th day after the application for reheating was filed).
