Well names currently include a forward slash "I" followed by an obsolete bottom hole location designator. HAK would like to retain the well number as well as the "A, B, C...." sidetrack designations but remove the "/suffix". For example, "DUCK IS UNIT SDI 1-09A/L21" would become "DUCK IS UNIT SDI 1-09A". The attached spreadsheet includes original and new names for all Duck Island wells. While performing the review of Duck Island well names, HAK found a single well, "DUCK IS UNIT SDI 4-20/M35" (PTD # 1861730), that should also be modified to include an "A" label to reflect the fact that the well is a sidetrack from the original "DUCK IS UNIT SDI 4-20/T34" (PTD# 1861500). The original wellbore, abandoned 10/13/1986, was sidetracked to a new bottom hole location completed on 9/9/1987. This well appears to be one of the first sidetracks performed at Endicott. While the bottom hole code was changed, no letter was added to reflect the sidetrack. "DUCK IS UNIT SDI 4-20A" is also included on the attached spreadsheet.

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.

Surface casing was run to 4,737' and the open hole extends to TD at 12,090'. A plug was left from 10,888' to 12,090'. A second cement plug extends from 4,424 to 5,228' MD. The well is mechanically sound as indicated by a passing MIT-IA to 3000 psi and a passing MIT-OA on 12/10/04. The well will not allow the migration of fluids, will not damage freshwater or producing or potentially producing formations, will not impair the recovery of oil or gas, and is secure, safe and not a threat to public health. The strata through which the well was drilled is neither abnormally geo-pressured or depleted. Condition of the Wellhead and Surface Location Duck Island Unit well MPI 1-59/024 is located on an active, well maintained pad with clean gravel. The pit and surrounding area are in good condition. There is no discoloration and no sheens on the pad, pits, or in nearby water. The well pressure readings are T/I/O = 0/0/0. Request BPXA requests approval for renewal of the existing suspension status for MPI 1- 59/024. A variance to the provisions of 20 AAC 25.110 (c) (2) is also requested under 20 AAC 25.112 (i) to allow the well to remain as suspended in its current condition. All hydrocarbon intervals are isolated and there are no underground sources of fresh water in this area. STATE OF ALASKA ALASKA~AND GAS CONSERVATION COMMISSION REPORT OF SUNDRY WELL OPERATIONS 1.

DISCUSSION , SURVEY CERTIFICATION SHEET SR325.DOC DISCUSSION JOB NUMBER: AK0296G325 Tool 080 was run in MPI Unit, 1-59/O-24 on ATLAS 5/16" Wireline inside drillpipe. The survey was run without problems. After obtaining a post job MBO on tool 080, we discovered a shift in the physical mass of the gyro. The tool was sent to Houston and re-calibrated. The new calibration has been applied to the final survey, and reflects the corrected data in this report. Prior to running this gyro, a Iow frequency, high G shock affected it's calibration. The post run MBO shows this change. After applying the post run MBO and reprocessing the data with the new calibration, we are submitting this survey with confidence that it is within our guidelines for accuracy. SR325.DOC gyro/data SURVEY CERTIFICATION SHEET JOB NUMBER' AK0296G325 The data for this survey and the calculations for this survey were obtained and performed by me according to standards and procedures as set forth by Gyrodata Limited, true and correct to the best of my knowledge. TOM STODDARD OPERATIONS ENGINEER The data and calculations for this survey have been checked by me and conform to the standards and procedures as set forth by Gyrodata Limited. This report represents a directional survey of this well based on the original data obtained at the wellsite. The data has been reprocessed with the latest calibration.

The estimated MD of the Kekektuk is 10611' DRILLING HAZARDS & RISKS The driller should monitor the well carefully while drilling from 10,700' to 10,800' due to the possibility of potential high pressure, A leakoff of 13.9 ppg on 2-48/O-13,13.0 ppg on 1-0:3 / P-16 and 12,55 on 1-65/N-25 was achieved Any leakoff less than 12 ppg must be reported to drilling superintendent prior to drilling ahead. COMPLETIONS Recent Lessons Learned 1-03/P-16 Had trouble landing plug in the XN nipple at 50 degrees in the liner top, Bell guide worked good however. Therefore it is suggested that the liner top be pulled up to 45 degrees in the future completion. The plug was actually catching in the collar of a tubing joint above the XN nipple but it acted like it was in the profile in that the they pulled against it. It the would have pumped it would have probably gone in, Pumping was required to seat the standing valve, 1-65/N-25 Pumped until bumped on long string. Unable to get wireline tools to fall below 55 degrees. Suggestion to make conditioning run prior to Ioggs considering that we have to pick up 3.5" DP next. lnhanced mud conditioning properties now being requested (less progressive gels) may also be benefitial. Hazards and Contingencies 1-59 / O-24 Hazards Pressure: Abnormally high pressures may be encountered in the 3C/3B due to gas injection approximately 1500' downdip of the target location at well 1-15/P-25. The driller should monitor the well carefully while drilling from 10,700' MD to 10,800'MD. Zone Pressure.(psi~_~ Depth ~CI'VDSS) 3C Truncated 3B 5230 9705 2B 4638 9955 2A 4~ 101~0 1 ~89 10315 Note: These pressures are estimates, based on zonal pressure surveillance in surrounding wells. Original reservoir pressure (4890 psia @ 10000 TVDSS) may be encountered at any point within the Kekiktuk, due to hydraulio discontinuities within the formation. 1-59/O;24 Well Plan Version Page 7 Date 12/31/96 MEMORANDUM State ot Alaska Alaska Oil and Gas Conservation Commission DaVid TO: Johns_.~, DATE: Chairman--~-~ :.

As the attached AOGCC Diverter System Inspection Report shows the diverter system was installed properly under the conditions the lines have to be installed to insure as much safety as possible for everyone concerned. With the confines of the well houses, flow lines, pipe supports, both on the pad and overhead, the system is installed, in my opinion, the best way possible. The rig was clean and all equipment seemed to be in good working order. The location was clean and ali tools and equipment were stored propedy and there was good access to ali areas of the rig. While testing the accumulator ! noticed that all of the four way valves had been repaired as i had requested on a previous inspection trip. Summary:. I witnessed the satisfactory function test and inspected the installation of the diverter installed on Doyon rig 15 drilling BPX' DIU 1- 59 / 0-24.

Metzger Area Production Engineer BP Exploration (Alaska) Inc. P. O. Box 196612 Anchorage, AK 99519-6612 Dear Mr. Metzger: We have received your correspondence dated December 18, 1995 requesting a spacing variance for the Endicott 1-59/0-24 well.- As proposed, this well will penetrate the top of the 2B interval of the Kekiktuk Formation within 175 feet of the 5-02/SD-10 well. Well 5-02/SD- 10 is a water injection well completed in the Zone 2A interval of the Kekiktuk Formation. The subject well will be drilled as a horizontal producer in the 2B interval. The drilling and co/npletion of the 1-59/0-24 2B zone production well will not interfere with 2A zone injection operations in the adjacent 5-02/SD-10 well. The Commission has determined placement of the well will not promote waste, will enhance recovery, and hereby approves the drilling of the Endicott 1-59/O-24 well as proposed pursuant to Rule 3 of Conservation Order No. 202.
