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.

Continued drilling from 11029 to 11067 where the Sag sand was encountered, good drlg break. Re-oriented and continued drilling from 11067 to 11130' and had a better drilling break with slight mud loss. Drill to 11221'. Backream to top of OH sidetrack at 10595'. Tie-in at 10900' (add 4.0') while losing 18 BPH and when finished were losing 36 BPH. Add 4 ppb liquid casing to mud while RIH. Drill from 11221 to 11322' dropping angle to catch Sag in anticipated downthrow of fault that showed on GR at 11220'. Losses decreased to 3 BPH, but were having trouble with MWD signal (due to LCM).

Stopped w/btm of whipstock estimated at SN nipple. Could not get past. Could not wedge fish solidly there either. Total of 27 jar hits used. Released from fish and pulled out. Picked up three drill collars and accelerator to assist jars. Ran in and relatched fish on btm at estimated 11427 CTD. Pulled back to tail pipe with 6K drag again. Fish stopped with btm estimated at end of tail pipe. Rattled fish along 7 inch liner to try to clean up same. Picked up and worked fish into tail pipe. Jarred a total of 7 times and jars quit working. Made 3 ft of progress with fish in tailpipe. Fish wedged in tail pipe firmly. Released from fish and pulled out to change jars.

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 permit is for a new segment from existing well A-26, API No. 50-029-20794-00. Production should continue to be reported as a function of the original well identifier. Blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25.035. Sufficient notice (approximately 24 hours) of the BOPE test performed before drilling below the surface casing shoe must be given so that a representative of the Commission may witness the test. Notice mav be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607.

The plan calls for a retrievable whipstock to be set in the 7" liner to permit drilling of a lateral into the Sag River formation. The open hole will be completed with a 2 7/8" slotted liner that will terminate just outside the window. The whipstock will then be pulled to provide access to lower Ivishak perforations. Existing perforations will not be squeezed. Ivishak perforations will be protected with carbolite and elevated LSRV FIoPro prior to setting the retrievable whipstock. The window will be milled through existing Sag R. perforations. The retrievable whipstock is not a sealing device and will permit production from below in the event that the whipstock cannot be retrieved. This procedure is described in the attached Form 401.

Because of complications in preparing well R-16 for sidetracking, we are now submitting an application to sidetrack weil A-26 prior to the sidetrack of R-16. The current coil sidetrack schedule is as follows: A-26L1 R-16L1 R-29A drilling expected to start June 11 (no abandonment) drilling expected to start June 25 (no abandonment) Perforation abandonment to start June 25, drilling July 9 I apologize for the changes in schedule and for the late submission of the A-26L1 form 401. Prep work for A-26L1 will begin on June 4 but will not involve abandonment of existing perforations. Ted Stagg CT Drilling Engineer cc: Well File Petrotechnical Data Center JUN 2 1997 BPX A-26L1 Sidetrack Summary of Operations: Well A-26 is being sidetracked to provide improved drainage from the Sag River formation.. This sidetrack will be conducted in two phases. Phase 1: Prep well and set retrievable whipstock: Planned for June 4, 1997. - The existing Ivishak perforations will be covered with carbolite and protected with high LSRV FIoPro. - A retrievable whipstock will be set on ELine at approximately 10,410' MD. Phase 2: Drill & Complete Sidetrack: Planned for June 11, 1997. - RU coil drilling unit and mill window in Sag River interval. - Drill the directional hole as per attached plan to planned TD of 11,883' MD (8,675' TVDss). Mud Program: - Phase 1: Filtered seawater, Carbolite, FIoPro - Phase 2: FIo-Pro (8.8 - 8.9 ppg) Casing Program: - 2 7/8", 6.16#, L-80, FL-4S slotted liner will be run from TD to approx. 10,430' MD and termintaed outside the window. The slotted liner will not be tied into the existing liner. Well Control: - BOP diagram for drilling and completion is attached. - Pipe rams, blind rams and the CT pack off will be pressure tested to 400 psi and to 4000 psi. - The annular preventer will be tested to 400 psi and 2000 psi. Directional - See attachments. - Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run.
