Attn: Well Integrity Coordinator, PRB -20 Post Office Box 196612 Anchorage, Alaska 99519 -6612 May 18, 2012 '3g �J 3 Mr. Jim Regg Alaska Oil and Gas Conservation Commission StAftiNED AUG 0 8 2-011 333 West 7 Avenue Anchorage, Alaska 99501 Subject: Corrosion Inhibitor Treatments of GPB H -Pad Dear Mr. Regg, Enclosed please find multiple copies of a spreadsheet with a list of wells from GPB Pad H 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.

Merv Liddeiow (BP Rep.) performed the SVS tests today. All components functioned propedy and held their pressure tests. The new style pilot boxes were installed on most of the wells, which combined with the reliability of the electronic pilots helped to produce these great results. The well houses were all clean with pilot valves in proper position. SUMMARY: I witnessed the SVS test on twenty BPX H pad wells in the Prudhoe Bay Field. 20 wells, 40 components, No failures. Wellhouse Inspections; 33 wellhouses, No problems noted.

SUMMARY: Fluid pack well with filtered sea water. Start in hole with TAM single set packer. Unable to get tools thru "X" nipple at 8445 ft CTD. Start out of hole with tool string. Pulled tight thru insert nipple at 2123 ft. Continue out of hole. Close swab and lay down tools. Tools were covered with metal shavings. Tools ok. Coil ok. Inside of BOP ok. Pick up 3.50" jet nozzle. Bring pump on line. "Wash" lubicator and tree. Start in hole with nozzle while circulating sea water and try to clean-out metal shavings. Washed all GLM and jewerly. Drop thru TT. Pulled out of hole while circulating. Finished out of hole. Close swab and wing valves. Remove fusible cap. Leave well SI. Resume ops in AM. Resume operations. Fluid pack well. Start in hole with BHA #3. Drop thru tubing tail. Pull back thru tubing tail and nipples. Had good locates. Make a (-) 10 ft correction. Repeat locates. Made no other corrections. Position packer with center element at 8953 ft. Drop ball and set packer. Hold safety meeting. BJ pressure test lines to 4000 psi. Perform injection test down coil at 1.5 bprn/3650 psi. Pump 75 bbls of 15% HCL/10% XYL with normal additives and acidize the perforations from 8958' to 8988'. Saw good "break" also noticed that well head pressure increased at same time. (Increase in WHP was due to communication "behind pipe", in my opnion). Flushed with 33 bbls of sea water and overdisplaced with 100 bbls of sea water. Release packer and ease up to tubing tail. Enter tubing tail and pull thru all nipples with no problem. Continue out of hole. Finished out of hole. Close swab and remove fusible cap. Lay down packer. Lay down tools. Rig down unit. Leave well shut in for "flowback" thru Trico. Tam Single set packer worked perfect. Lost approximately 20% of the rubber from the lower element. All bands recovered. Tools were covered with metal shavings from "trash" in well.

As the attached AOGCC BOP Test Report indicates one failure was observed on the upper pipe ram door seal. The seal was replaced and testing was resumed with no further failures. The area around the rig' was extremely tight, but well laid out with plenty of access for any emergency vehicles. Nabors has installed a new test manifold and pump controls on the rig floor, this new arrangement cuts down on confusion and helps speed up the testing. Summary: I witnessed the BOP test on Nabors 18E BPX / PBU / well H-33 with one failure, 4.5 hours.

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. 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 may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607.
