Anchorage, Alaska 99501 �`�( Subject: Corrosion Inhibitor Treatments of GPB A -Pad liA .P.";1n Dear Mr. Regg, Enclosed please find multiple copies of a spreadsheet with a list of wells from GPB Pad A that were treated with corrosion inhibitor in the surface casing by conductor annulus. 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, Gerald Murphy, at 659 -5102. Sincerely, Mehreen Vazir BPXA, Well Integrity Coordinator • • BP Exploration (Alaska) Inc.

This sidetrack will be conducted in two phases. Phase 1: set whipstock, abandon existing perfs, mill window: Planned for 11/24/98. · A-27i will be tested for mechanical integrity, drifted for the whipstock and a Kinley caliper will be run to evaluate liner and tubing condition. · A Schmoo-Be-Gone treatment will be performed to eliminate mung from the wellbore. · Existing perforations will be abandoned with approx. 25 bbls cement. Abandonment cement will be downsqueezed past a mechanical whipstock set within Sag R. perforations at approx.8,880'. Abandonment cement will be squeezed to 2200 psi with AOGCC witness. This procedure is described in more detail in the Form 10-403. · Service coil or drilling coil will mill the window utilizing a flowline to the GC for all fluid returns. The service coil or drilling coil will conduct a full BOPE test, with AOGCC witness, prior to the milling operation. Phase 2: Mill Window and Drill Directional Hole: Planned for 12/08/98. Directional drilling coil tubing equipment will be rigged up and utilized to drill the directional hole as per attached plan. Mud Program: - Phase 1: Seawater - Phase 2: FIo-Pro (8.8 - 8.9 ppg) Casing Program: - 2 7/8", 6.16#, L-80, ST-L liner will be run from TD to approx. 8,464' MD and cemented with approx. 28 bbls. cement. The top of cement will be designed to be a minimum of 200 ft above the window. A Cement Evaluation Log will be run across the upper portion of the liner and pressure testing will be carried out to confirm mechanical integrity. The well will then be perforated with coil tubing conveyed guns. Well Control: - BOP diagram 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. - Kick Off: 8895' MD (8,693' TVD ss) - TD: 11,197' MD (8,949' TVD ss) - Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. Logging · A Gamma Ray log and a phase resistivity log will be run in the open hole section. · A Cement Evaluation Log will be run in the upper portion of the 2 7/8" liner. Mud and Cuttings disposal: All waste mud and cuttings will be injected at the CC2 facility. Drilling Hazards: Two faults with potential for lost circulation are expected on this sidetrack. MagnaPlus will be used as the primary cure for significant losses. TREE: 6" CAMERON WELLHEAD: MCEVOY ACTUATOR: OTIS t ',-27ai Proposed Completior{- KB. ELEV - 87.2 BF.

(8) The Directional Surveys used to calculate the TVD's were acquired from Sperry-Sun Drilling Services. (9) The data has been edited from the raw field data. The log and relog sections for Run 3 have been individually depth shifted to the Primary Depth Control supplied by BP Exploration. (10) Because of the interm/ttent tool failures on the relog, the data from the log run was used to supplement the gaps in the relog. ~Mnemonics -> GRAM = Gamma Ray MWD-API [RWD] (MWD-API units) -> RACLM = Resistivity Compensated 400 KHz Attenuation Resistivity Long Spaced Borehole Corrected [RWD] (ohm-m) -> RPCLM = Resistivity Compensated 400 KHz Phase Difference Resistivity Long Spaced Borehole Corrected [RWD] (ohm-m) -> RACHM = Resistivity Compensated 2 MHz Attenuation Resistivity Long Spaced Borehole Corrected [RWD] (ohm-m) -> RPCHM = Resistivity Compensated 2 MHz Phase Difference Resistivity Long Spaced Borehole Corrected [RWD] (ohm-m) -> TVD = True Vertical Depth (feet) ~Sensor Offsets RUN GAMMA 3 17.13' Tape Subfile: 1 Minimum record length: Maximum record length: RESISTIVITY SURVEY 24.48' 37.71' 72 records... 14 bytes 132 bytes Tape Subfile 2 is type: LIS **** FILE HEADER **** MAD .001 1024 *** INFORMATION TABLE: CONS MNEM VALU LCC 150 CN BP Exploration WN A-27AI FN Prudhoe Bay Unit COUN North Slope STAT Alaska LIS COMMENT RECORD(s): ~234567890~23456789~~234567890~234567890~234567890~234567890~234567890~234567890 !!!!!!!!!!!!!!!!!!!
