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 • 0 BP Exploration (Alaska) Inc.

It had been completed with 2-7/8" cemented liner for use as a horizontal MIST injector. Water was injected between bulbs of MI at rates of 10 MBWD. It was then converted to a producer in October 2001. Well 9-31 did not flow oil until additional perforations were shot in Zone 4. Unfortunately, production quickly fell below 100 BOPD. It was finally shut-in for high water cut and low oil production in August 2003. 9-31 C is currently being converted to a water injector pending completion of surface conversion. It is hoped that the actual surface conversion will be completed by 4Q of this year. This program requests well preparation and MITIA to confirm integrity in inner annulus. 9-31 is ready for injection as soon as the IA test is completed, and appropriate state approval has been obtained.

Well 09-31C was drilled and converted to an injector as a lateral MIST project in April 1996 (Permit to Drill 96-64 signed 4/1/96). This conversion back to producer status is part of the original scope of the project. The well currently exhibits mechanical integrity as an injector. No facility modifications are required for this conversion. Current plans are to isolate the Zone 2C perforations that took MI injection and complete the well in Zone 3 and Zone 4. If you have any questions concerning this Sundry Application, please don't hesitate to call me at 564-5764 or E-mail me at watsonJD@bp.com. Sincerely, aon BPXA DS 9 Surveillance Engineer TREE = ?

The permit to redrill 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 blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25.035; and the mechanical integrity (MI) of the injection wells must be demonstrated under 20 AAC 25.412 and 20 25.030(g)(3). Sufficient notice (approximately 24 hours) of the MI test before operation, and 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 tests. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607.
