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".

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.

Logs and tapes were sent to you for each of these wells in the past year. Rigcently Anadrill has improved the density algorithm and re- created all of our LWD CDN data using the new algorithm. This processing decreases the density a couple of porosity units, making the readings more accu rat e. · Please replace the first set of tapes and the first set of CDN logs we sent you so that these improved logs are used for your analyses. The NK-21 blueline and sepia you received in December were the re-processed version and, therefore, do not need to be replaced. Per 20.AAC 25.537(d) BP Exploration requests that these logs held confidential for 24 months. Please contact me at 564-4531 if you have any questions.

Box 196612 Anchorage, Alaska 99519-6612 (907) 561-5111 VIA FACSIMILE June 13, 1994 Mr. David Johnston Chairman, Alaska Oil and Gas Conservation Commission 3001 Porcupine Drive Anchorage, Alaska, 99501-3192 Subject: Request for Waiver to 20 AAC 25.240 - Niakuk Oil Pool Dear Mr. Johnston, BP Exploration (Alaska), Inc., operator of the Niakuk Oil Pool, hereby requests a waiver to statewide 20AAC 25.240 (b) (Gas Oil Ratios) on producing well Niakuk 20 in the Niakuk Oil Pool, Prudhoe Bay Unit. Waiver from this rule is being sought as provided in 20 AAC 25.240 (c) (3), which states that the commission may, in its discretion, waive the requirement that a well not produce in excess of its original gas-oil-ratio by more than 100% if acquisition of pool performance data is necessary to determine an optimum reservoir management program. The producing GOR of Niakuk 20 has not exceeded this limit to date, however as outlined below, recent trends indicate that this may occur in the near future. In order to permit flexibility (such as well cycling, data acquisition timing/scheduling, etc.), we request that this waiver be granted until waterflood startup in April 1995. Niakuk 20 is located in the eastern segment of the Niakuk oil pool (known as Segment 2). It is completed in two zones within the Kuparuk interval and is the only well producing from these zones. Niakuk 20 has been on production since April 12 and has cumulatively produced about 176 thousand stock tank barrels of oil. The well's original producing GOR was approximately 656 SCF/STB, but the GOR has recently begun increasing as indicated by a June 7 test of approximately 1140 SCF/STB. This waiver is being sought to enable BP to continue to gather production and surveillance data which will help to determine how to optimally develop this area of the reservoir. Specifically, acquisition of additional data will help to determine the placement of wells, waterflood implementation strategy and formulation of an optimum reservoir management plan. Niakuk 20 is the only well that affords us an opportunity to gather data from these zones and we believe that the amount of information gathered is insufficient to accomplish this aim. Further data gathering is important to understand the size and nature of the reservoir, and ultimate well placement and utility. BP believes that this plan is in the best interests of the operator and the state. Produced gas is not being wasted; it is either being used for fuel or being injected into the Lisburne reservoir. We also remain fully committed to waterflood implementation and expect startup to occur in April of next year. We appreciate your prompt attention to this matter. Robert W.

The permit to drill 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 (B~PE) must be tested in accordance with 20 AAC 25.035; and the mechanical integrity (MI) of the injection wells must be demonstrated under 20 AAC 25.412 and 20 25.030(g)(3). Sufficient notice (approximately 24 hours) of the MI test before operation, and of the BO?E test performed before drilling 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 Commission petroleum field inspector on the North Slope pager at 659-3607.
