Terrie Hubble, 564-4628 Dave Wesley, 564-5153 GENERAL: This form is designed for submitting a complete and correct well completion report and log on all types of lands and leases in Alaska. ITEM 1a: Classification of Service Wells: Gas Injection, Water Injection, Water-Altemating-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). 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 8: 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 A-30 is a low angle (480 max) conventional water-flood producer. It was drilled and completed in June 1985. Initial oil rates were 7,000 BOPD with 0% WC. A channel to water was found in July 1990; 3 squeezes were needed to control the water, but oil rate suffered too, so the well was fractured (Ivishak only) and stimulated in December 1990. Oil production increased from 1,000 to 3,000bopd and the water cut returned to pre-squeeze levels r' (-40%). An acid stimulation in April 1988 gave a response of 1000bopd, but subsequent stimulations (10/89, 7/90 and 7/00) have not improved rates. Fluid rates had been maintained at about 2,000 bfpd and a static survey in May 2001 gave a pressure reading of 3,337psi, which suggests good support for the parent location. Small MI responses have also been noted, most likely from A-17i and X-06i. The well has /' open perforations in the Sag, but their contribution is likely small. Well A-30L 1 has been shut in since the lateral leg was attempted in May 2003 when it was producing 250bopd at 88% water cut and 6200 GOR. A-30A, a proposed 3,050' Zone 4B horizontal rig sidetrack, will parallel the original A-30 and A- , 30L 1 and extend an additional 1,850' beyond the A-30L 1 planned TD. It will target a potentially large oil . /' reserve left by inefficient sweep between four offset injectors (X-06i, A-17i, A-21i, X-29i). The planned profile will crosscut stratigraphy four times, staying well above a possible MOWC at -8,900sstvd. Real- time geo-steering sensors will be used to continuously evaluate fluid saturations and an early TD will be called if pervasive high water saturations are encountered. The A-30A sidetrack is scheduled for Nabors 7ES. Current estimates have it beginning around May 25, 2004, following the completion of the P-27. The pre-rig work for this sidetrack is planned to begin as soon as the attached Application for Sundry is approved. Scope Notify the field AOGCC representative with intent to plug and abandon Pre-Ria ODerations: 1. RIU and pressure test the 4 1/2" tubing string, against the cemented coil tubing fish, to 3,OOOpsi. Determine whether or not the well is effectively plugged and abandoned by the cemented fish. (Done /' 4/14/2004. Injection rate of 4.9bpm established at 1)9°PSi. Also, conducted MIT IA to 3,000psi for 30 minutes and MIT OA to 2,000psi for 30 minutes.) /' 2. RIH and set a 4 Yz" cementing retainer at -3,550'md. . 3.

A-12, -13, -26, -30, -34A, & -37 Dear Mr. Farris/Bixby: On July 18, 1994, our Inspector Lou Grimaldi witnessed no-flow tests on BPX's PBU A Pad wells 12(PTD 80-117), 13(PTD 81-159), 26(PTD 82-117), 30(PTD 85-119), 34A(PTD 85-105), and 37(PTD 93-007). The wells had been shut in on the previous day. All wells were bled down to atmospheric tanks on-site. Five of the wells were essentially dead; the sixth well (A-30) made a small amount of gas; a gas meter showed that the flow rate was approximately 360 SCF per hour versus 900 SCF per hour acceptable. Since these rates are well below the limits for "no-flows", the Inspector concluded that subject wells were not capable of unassisted flow of hydrocarbons. The Commission hereby authorizes removal of the subsurface safety valves from BPX's PBU wells A-12(PTD 80-117), A-13(PTD 81-159), A-26(PTD 82-117), A-30 (PTD 85-119), A-34A(PTD 85-105), and A-37(PTD 93-007) on the condition that the low-pressure sensors and surface safety valves must be maintained in good condition and, if for any reason, the wells again become capable of unassisted flow of hydrocarbons, the subsurface safety valve(s) must be reinstalled and maintained in good working condition.

Supervisor FROM: Lou Grimaldi, ¢'-"~' SUBJECT: Petroleum Inspector FILE NO: 9A9JGRBD.DOC No Flow verification BPX wells A-12,13,26~4,&37 Prudhoe Bay Field Sunday, July 17,1994; I verified the NO-FLOW status of 4 BPX wells, A-12,26,34 &37, in the Prudhoe Bay field. The subject wells had been flowed down to separator pressure the night before and then bled to zero in a bleed trailer. All four wells were dead either no gas flow or just a whisper when opened to atmosphere. ! recommend the approval of the NO-FLOW status for these wells. Monday, July 18, 1994; I returned to A pad today and verified NO FLOW status on well # A-13. This well like the others produced no fluid or had significant gas flow. There was a additional well tested, this being A-30. Although no fluid was produced a small amount of gas was steadily coming from the tubing. A residential type gas meter was installed on a hose routed from the tree cap to. The pressure was stabilized at approximately .5 psi with the meter registering on the two foot scale thirty subdivisions (or three revolutions) in thirty seconds. As there were no instructions with this meter and we were not sure of its operation I did not approve the test at this time, if the instructions prove out that two standard cubic feet is measured per revolution instead of a subdivision this well would pass the NO FLOW test. SUMMARY: I witnessed NO-FLOW tests on six BPX A pad wells. BP EXPLORATION RECEIVED '.' ~.~Oil & ~as Cons. Oommissjon Anchorage BP Exploration (Alaska) Inc. 900 East Benson Boulevard RO.

Pump cement and squeeze existing channel from 11014'- 11080' MDBKB to ensure success of the Ivishak fracture to follow. 3.) Reverse out cement after squeeze is obtained. Wait 12 hours, then test squeeze by performing inflow test. If squeeze fails, immediately resqueeze. 4.) If squeeze is successful, perforate the following.interval:. 10914'-10924' MDBKB 5.) Return well to production. 6.) Perform the WPWZ Single Well Chemical Tracer Test. 7.) Perforate the following intervals: 10877'-10896' MDBKB 10900'-1 0906' MDBKB 10932'-1 0962' MDBKB 8.)

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. Samples of drill cuttings and a mud log are not required. A continuous directional survey is required as per 20 AAC 25.050(b)(5). If available, a tape containing the digitized log information shall be submitted on all logs for copying except experimental 1.ogs, 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).
