• • BP Exploration (Alaska) Inc. Attn: Well Integrity Coordinator, PRB -20 Post Office Box 196612 Anchorage, Alaska 99519 -6612 July 6, 2011 ;► .1�; L I 8 ZO1 a Mr. Tom Maunder Alaska Oil and Gas Conservation Commission 333 West 7 Avenue Anchorage, Alaska 99501 Subject: Corrosion Inhibitor Treatments of GPMA Niakuk Dear Mr. Maunder, Enclosed please find multiple copies of a spreadsheet with a list of wells from GPMA Niakuk 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, Mehreen Vazir, at 659 -5102. Sincerely, Gerald Murphy BPXA, Well Integrity Coordinator • • BP Exploration (Alaska) Inc.

Well house inspections were also conducted. The testing went well with Ron White as the BPX representative in charge of testing. 12 wells were tested with two failures witnessed. The pilot on NK-12A tripped below 50% of the separator pressure and was replaced and passed a retest. The SSV on NK..62 failed to hold D.P. and was stroked and passed a retest. I inspected 12 well houses and all were in order with no exceptions noted. The AOGCC test forms are attached for reference. ~ I witnessed SVS tests on 12 oil producing wells in BPX's Niakuk Field. 12 wells tested, 36 components. 2 failures witnessed, 5.50/0 failure rate. 12 well houses inspected, no, exceptions noted.

The permit to drill does not exempt you from obtai~ing 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 th Slope pager at 659-3607.
