ITEM 1a: Classification of Service Wells: Gas Injection, Water Injection, Water-Alternating-Gas Injection, Salt Water Disposal, Water Supply for Injection, Observation, or Other. Multiple completion is defined as a well producing from more than one pool with production from each pool completely segregated. Each segregated pool is a completion. ITEM 4b: TPI (Top of Producing Interval). ITEM 8: The Kelly Bushing elevation in feet above mean low low water. Use same as reference for depth measurements given in other spaces on this form and in any attachments. ITEM 13: The API number reported to AOGCC must be 14 digits (ex: 50-029-20123-00-00). ITEM 20: True vertical thickness. ITEM 22: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. ITEM 23: If this well is completed for separate production from more than one interval (multiple completion), so state in item 1, and in item 23 show the producing intervals for only the interval reported in item 26. (Submit a separate form for each additional interval to be separately produced, showing the data pertinent to such interval). ITEM 26: Method of Operation: Flowing, Gas Lift, Rod Pump, Hydraulic Pump, Submersible, Water Injection, Gas Injection, Shut-In, or Other (explain). ITEM 27: If no cores taken, indicate "None". ITEM 29: List all test information. If none, state "None".

NK-14 was completed in 6/96 as producer with 4-112" tubing The well was initially perforated in 5AA, 4AA, 4BB, and 3AA zones. 6FS perfs were added in 9/01 with no apparent benefit. NK-14 sees injection support from NK-15. 3 PPROFs have been run, 2 in 1997 and one in 2001. The logs from 1997 indicated 90% of the flow is coming from the lower large set of perforations. The log in 2001 indicated 38% of fluid contribution from the lower perfs and 62% from the upper zone. However, the lower perfs were contributing mostly water. Only 16% of total oil production comes from lower perfs and 84% from upper perfs. Production decreased on 6/00 due to the well being SI for D&T and SBHP. The gas lift was redesign in 4/01 with no significant rate change. Another GL redesign in 4/02 resulted in additional-2oo BOPD. Oil production has been steadily declining over the last two years. NK-14 has been selected for a through tubing sidetrack with the SLB/Nordic 1 Coiled Tubing Drilling rig on or around March 15.2006. The sidetrack, NK-14A, will exit the existing 7" liner and kick off and land in zone 4BB. The existing perforations will be isolated by a ,.- cement squeeze.

Well house inspections were also conducted. The testing went well with Ron White as the BPX representative in charge of testing. 12 wells were tested with two failures witnessed. The pilot on NK-12A tripped below 50% of the separator pressure and was replaced and passed a retest. The SSV on NK-62 failed to hold D.P. and was stroked and passed a retest. I inspected 12 well houses and all were in order with no exceptions noted. The AOGCC test forms are attached for reference. SUMMARY: I witnessed SVS tests on 12 oil producing wells in BPX's Niakuk Field. 12 wells tested, 36 components. 2 failures witnessed, 5.5% failure rate. 12 well houses inspected, no exceptions noted.

An affected person has 30 days from the date the Commission refuses the application or mails (or otherwise distributes) an order upon rehearing, both being the final order of the Commission, to appeal the decision to Superior Court. Where a request for rehearing is denied by nonaction of the Commission, the 30-day period for appeal to Superior Court runs from the date on which the request is deemed denied (i.e., 10th day after the application for rehearing was filed).

The permit to ddll does not exempt you from obtaining additional permits required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permitting determinations are made. The blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25.035; and the mechanical integrity (MI) of injection wells must be demonstrated under 20 AAC 25.412 and 25.030(g)(3). Sufficient notice (approximately 24 hours) of the MI test before operation, and of the BOPE test performed before ddlling below the surface casing shoe, must be given so that a representative of the Commission may witness the tests. Notice may be given by contacting the e North Slope pager at 659-3607.

Alaska Oil and Gas Conservation Commission · Re: The application of BP EXPLORATION (ALASKA) Inc. for exception to 20 AAC 25.055 to allow drilling the Niakuk No. 14 development oil well. BP Exploration (Alaska) Inc. by letter dated March 22, 1996 has requested an exception to the provisions of 20 AAC 25.055(a)(3) for the drilling of a development oil well to an undefined oil pool within the Kuparuk River Formation adjacent to the northern boundary of the Niakuk Oil Pool Participating Area, on the North Slope. The exception would allow BP to directionally drill the Niakuk No. 14 development oil well to a producing location in an undefined oil pool that is closer than 500 feet from a quarter section line. The proposed surface location is 3921 '. from the north line (FNL) and 944' from the east line (FEL) of Section 36, T12N, R15E, Umiat Meridian (UM) and the proposed bottom hole location is 1388' FNL 2397' FEL of Section 23, T12N, R15E UM. A person who may be harmed if the requested order is issued may file a written protest prior to 4:00 PM April 11, 1996 with the Alaska Oil and Gas Conservation Commission, 3001 Porcupine Drive, Anchorage, Alaska 99501, and request a hearing on the matter. If the protest is ~imely filed and raises a substantial and material issue crucial to the Commission's determination, a hearing on the matter will be held at the above address at 9:00 am on April 26, 1996 in conformance with 20 AAC 25.540. If a hearing is to be held, interested parties may confirm this by calling the Commission's office, (907) 279-1433 after April 11, 1996.
