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. If you require any additional information, please contact me or my alternate, Mehreen Vazir, at 659 -5102. Sincerely, Gerald Murphy BPXA, Well Integrity Coordinator • • BP Exploration (Alaska) Inc.

Mr. J. L. Harris Operations Engineering Supervisor Lisburne/Point McIntyre Engineering ARCO Alaska, Inc. P. O. Box 100360 Anchorage, Alaska 99510-0360 Dear Mr. Harris: We have received your letter of November 5, 1992 requesting approval to perform a production test using the Lisburne L5-24 well. The test will utilize a coiled tubing completion which is expected to act as a downhole separator and will require annular production of the gas. The test will prove whether or not gas can be separated downhole to provide a gas source with high flowing pressures. Pursuant to Rule 12 of Conservation Order No. 207 the Commission hereby approves the annular production of gas in L5-24 during the proposed test.

Smith Alaska Oil and Gas Conservation Commision 3001 Porcupine Drive Anchorage, Alaska 99501 Dear Mr.. Smith, Upon the startup of the Lisburne Production Center in mid-December, 1986, Lisburne pre-production testing will end and Lisburne well work with currently approved sundries notices will not be done as pre-production testing. Consequently, the enclosed sundry notices are being reported as completed, even though their entire proposed program may not have been completed. The only currently approved programs which will be completed in the future and will require a Report of Sundry Well Operations at completion are for Lisburne wells L5-24 and L3-2. The well condition summary information reported .is the well condition at the date of the last sundried work. The production or injection rate and tubing pressure data are our current startup estimations for the wells. The casing pressure is the pressure on the tubing/casing annulus on December 2, 1986. We appreciate your help and co-operation during this pre-production phase and look forward to working with you as we produce the Lisburne Oil Pool. Sincerely, B. T.

Box 100360 Anchorage, AK 99510-0350 Dear Hr. Foster: Now that the "Ltsburne Unitization Letter Agreement" of August 5, 1986 has been signed, Standard Al&ska Production Company (SAPC) concurs with t'teld-wtde reservoir development that accelerates into e&rly 1987 dri111ng and production of the L5 fleld area. Stand~rd recommends that drt111ng begin on L5 upon completion of the current upstructure wells on L3 pad (L3-18, L3-22, L3-24, L3-30). Additionally, SAPC recommends that production testing be performed on well L5-24 tn the near term tn order to further define the reservoir potential of the L5 area. In order to meet the goal of L5 drilling in early 1987 we understand conductors must be set thls year. As the Lisburne Special Supplementary Provisions to the Prudhoe Bay Unit-Operating Agreement ("PBUOA") are not yet signed, SAPC hereby grants permission to ARCo Alask&, Inc. to conduct Tract Operations tn the Ltsburne Reservoir (as defined in the Llsburne Agreement) pursuant to Article 8 of the PBUOA on the SAPC leases within the boundaries of the Ltsburne Participating Area as sho~n in Exhibit B of the L1sburne Agreement. These Tract Operations shall be conducted under the existing provisions or the PBUOA, Including Section 8.006. Tract Substances and Unit Expense for these T~act Operations ~tll be sh~red in accordance with the Ltsbu~ne Agreement. This request and authorization for Tract Operation shall terminate upon the effective date of the PBUOA Special Supl~lemental. Provisions or January 15, 1987, whichever first occurs.

Tuesday, June 11, 1985: I traveled this date from Anchorage via Alaska Airlines to Prudhoe Bay.. I drove to Sohio's L5-24 to witness a P&A on the Lower Lisburne zone. The first plug was tagged at 11,130 feet, this plug was 100 feet below the 9 5/8" casing shoe. I witnessed the displacement of the cement on the. second plug, W.O.C. for eight hours and the plug was tagged 'at 10,950 feet with 12,000 pounds and pressure tested with 3,000 pounds for 30 minutes and no leak off. There was a permanent bridge plug set at 10,945 feet. There was 12,000 pounds set on top of the bridge plug and it was pressure tested to 3,000 pounds for 30 minutes and no leak off. In summary, I witnessed the P&A on Sohio's Lower Lisburne zone on L5-24. (See attached drawing with this report).

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 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 con~nencing operations you may be contacted by the Habitat Coordinator's Office, Department of Fish and Game. Pollution of any 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.

In the application it was noted that the Sag Delta No. 6 well was drilled from the same pad that will be used as the surface location of the L5-24 well. It was also noted that the Sag Delta No. 6 well did not encounter any problems with shallow gas while drilling the surface hole to 2700 feet. This letter will advise you that the Commission has examined the evidence available and hereby waives the requirements of 20 AAC 25.035(b)(1) for this well and future wells on pad L5.

In the event that the Sadlerochit is present and logs indicate significant porosity/permeability, an alternative plan will be given consideration whereby 9-5/8" casing is set prior to penetrating the Lisburne. APP, 0 9 19B5 Gas Cons. commission klaska Oil & Gas Con~;vation Commission April 8, 1985 Page 2 o At this time, we request a waiver for installation of a diverter on the 20" conductor. Sag Delta ~6 which is located approximately 370' from L5-24 did not encounter any problems with shallow gas when drilling 17-1/2" surface hole to 2700'. In addition, we request a waiver to allow the use of 13-3/8" 729 SOO-95 buttress casing in lieu of L-80 grade for surface casing. We request this since current stock levels of L-80 casing in our exploration inventory from which this well is to be supplied are too low to meet the requirements of this well. If you have any questions, please call Dick Maskell at 564-5551.

Run 9-5/8" 479 L-80/S-95 casing from surface to 10,999' with S-95 up to 7500' TVD and L-80 from 7500' TVD to surface. Cement in two stages. The first stage will place Class 'G' cement around the shoe and the second stage will place Coldset cement followed by non-freezable fluid in the 9-5/8" x 13-3/8" annulus by downsqueezing through the wellhead side arm valve. Note that the second stage cement job will not be performed until after well TD has been reached to allow drilling mud to be disposed of by injection down the 9-5/8" x 13-3/8" annulus. Drill and core 8-1/2" hole directionally to 12,293' MD (10,370' TVD) performing two open hole drill stem tests. Run open hole logs. Run 7" 29~ L-80 buttress liner from 12,293' MD up to 10,849' MD and cement with Class 'G' cement. Perform cased hole drill stem tests including stimulation operations through the 7" liner. If warranted by results of drill stem testing, the well will be completed for a long term production test. At the conclusion of testing operations, the well will be suspended in accordance with all applicable state regulations.
