Anchorage, Alaska 99519 -6612 December 20 2010 a JAN 4 ZUi Mr. Tom Maunder i ° ‘' Alaska Oil and Gas Conservation Commission 333 West 7 Avenue n �`n, ri�tisa'<° , ��ssion Anchorage, Alaska 99501 A11t;n "utie Subject: Corrosion Inhibitor Treatments of GPB Y Pad ,. 0 G ( Dear Mr. Maunder, 3 i Enclosed please find multiple copies of a spreadsheet with a list of wells from Y Pad 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, Jerry Murphy, at 659 -5102. Sincerely, Torin Roschinger BPXA, Well Integrity Coordinator • • BP Exploration (Alaska) Inc.

Maximum possible bottomhole pressure is 4390 psi at 8800' TVDss based on original reservoir pressure. Maximum possible surface pressure is 3330 psi based on a gas column to surface from 8600' TVDss and an oil column to 8800' TVDss. Directionally drill 9-7/8" hole to the 7-5/8" casing point at the top of Sag River formation. Run 7-5/8" 29.7# L-80 NSCC casing to within 10' of 9-7/8" TD and cement with Class G cement around the 7-5/8" shoe. The annulus will be freeze protected by dry crude. Directional drill 6-3/4" hole to TD. Run 5-1/2" Chrome liner from TD to 250' inside 7-5/8" casing shoe and cement using Class G cement. Clean out to 5-1/2" landing collar. Change over to NaCL completion fluid. Test casing and lap to 3000 psi. Run 7-5/8" production packer on chrome tubing. Set packer 50' above top of liner. A subsurface safety valve with dual control lines will be placed 100' below base of permafrost. Install and test Xmas tree. Displace tubing to diesel. Set and test packer. The well will be perforated after rig release. Fluids incidental to the drilling of a well will be pumped down the 7-5/8" x 10-3/4" annulus of the well.
