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 • 0 BP Exploration (Alaska) Inc.

I found the rig and surrounding area to be in very good shape. Although the rig is using mineral oil based mud, the rig looked very good due to constant cleaning. Ail equipment I observed appeared to be functioning properly. The rig is due for a BOP test in approximately three days and i will attempt to witness same. Monday, November 25 ~991 I returned to L5-26 in the Lisburne Field to witness the weekly BOP test. The test went very well with all equipment holding the test pressure. In summary, I made a rig/BOPE inspection and witnessed a BOP test on AUDi Rig #2~ Well L5-26, for Arco. No noncompliances were found.

J:~proval No. Returnd~ , __ Commissioner Date J/-~)-E/ SUBMIT IN TRIPLICATE L5-26 SIDETRACK PROPOSED DRILL AND COMPLETE PROGRAM The subject well was originally drilled as a high-angle producer (13-3/8" x 9-5/8" x 4- 1/2" uncemented liner) in the Wahoo interval. While attempting to complete the well, the 8-1/2" production hole was lost, and was subsequently abandoned. L5-26 is currently plugged back to 9117' MD (inside 9-5/8" casing and above the K-10 marker). NOTE: While drilling the original well, a BHA was lost in the 12-1/4" hole. The open hole was sidetracked on the second attempt. These two sidetrack attempts are known as sidetracks #1 and #2. This sidetrack will be known as sidetrack #3. NOTE: The sidetrack geologic target is in the same direction as the original well, but is 400' closer to the L5 pad. After rigging up on L5-26 and conditioning the 9.0 ppg oil based mud, an 80' section will be milled from 8960' md to 9040' md. A cement plug will be set across the window and an attempt made to squeeze cement up behind the 9-5/8". A steerable BHA will be run to sidetrack at 9000' md / 7580' tvd at 220° from the high side. The target dogleg for the drop to the left will be 3.0°/100'. At the end of the drop/turn at 9428' md / 7853' tvd, the angle will be 45.5° at an azimuth of N32.1° E. In order to reach the drilling target, which is 175' NW of the geologic target, a 3.5°/100' build and right hand turn will be initiated at 9961' md / 8227' tvd. The build/turn will be complete (85° angle at N43.0° E) upon encountering the Lisburne target (Wahoo 5) prognosed at 11,122' md / 8705' tvd. A 7-5/8" protective liner will be set to case off the shales above the Lisburne. After centrifuging the oil based mud down to 8.5 ppg, 2180' of 6-3/4" hole will be drilled through the Lisburne maintaining the 85° angle and N43.0° E direction. NOTE: The original well did not use a drilling liner to case off the shales above the Lisburne. 9.0 ppg oil based mud was required to keep these shales open while drilling the production hole. This resulted in a loss of 7500 bbls of oil based mud. NOTE: Due to the presence of up to 5' thick shale breaks (57' md at 85°) within the Lisburne, oil based mud will be required in the production hole section also. One drill pipe conveyed logging run is planned. L5-26 will be completed with a 4-1/2" pro-drilled liner and 4-1/2" L-80 tubing.

Problems encountered while trying to complete the well, including parted 4-1/2 liner, a drill collar twist off, and sloughing shales, forced the decision to abandon the original production hole. Objective The objective of this procedure is to plug and abandon the hole below the 9-5/8" casing shoe so that preparations can be made and matedal acquired to sidetrack the well. The plan is to set a cement plug to extend at least 500' above the 9-5/8" casing shoe, run a casing inspection log of the 9-5/8" casing, set an additional EZSV and cement plug based upon the logging results and move the workover rig off the well. After a directional plan and casing program have been prepared and approved, a drilling rig will then move back over the well to sidetrack the well. It is estimated that preparations to sidetrack and redrill to a similar location could take as long as four months. Until such time, the well will be in an "Operation Shutdown" mode. Procedure 1. P/U 1200' of 3-1/2" drill pipe as a cement stinger. RIH to the 9-5/8" shoe. Ensure that the drill pipe is free to move. Circulate at highest rate possible to clean the cased hole above 9-5/8" casing shoe. . R/U Dowell, mix and pump the slurry listed below. Spot cement as a balanced plug with fresh water. The 390 sx (450 cuff) equates to 500' of 9-5/8" casing and the open hole with a 30" hole size. If the cement does not fall into the open hole, this volume equates to 1100'. o 390 sx Class "G" + 0.2% D65 dispersant + 0.2% DS00 retarder + 0.2% D46 defoamer o Slurry Weight: 15.8 ppg o Slurry Yield' 1.16 cuft/sx RECEIVED o Mix Water: 5.03 gal/sx o Thickening Time: 3:39 hrs ( Includes 1 hr at surface) o Fluid Loss: 1400 ccJ30 min NOV ! 5 ]990 41as~.0jl & Gas Cons.
