Alaska Oil and Gas Conservation Commission 333 West 7t" Avenue I ~ /~-- Q Anchorage, Alaska 99501 1~ jI f ~ ~ ~~ Subject: Corrosion Inhibitor Treatments of GPB DS 15 Dear Mr. Maunder, Enclosed please find multiple copies of a spreadsheet with a list of wells from GPB DS 15 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, Anna Dube. Sincerely, Torin Roschinger BPXA, Well Integrity Coordinator • BP Exploration (Alaska) Inc.

A sundry was not required due to the sundry waiver provision of CO 341C Rule 14. During the pre-squeeze prep work, a small casing leak (0.65 BPM at 3000 psi) was discovered 44 feet above the packer. Our plan is to shoot a tubing punch just above the packer and circulate in about 150 ' of cement above the packer as part of the liner top squeeze. The liner top and casing leak will both be squeezed together. As we discussed this afternoon, the casing squeeze is considered a well repair and therefore does not require a pre-job sundry. The job is scheduled to be done early next week. We will send the post job report as usual. If you have any questions please call me at 564-5596. 1 of 1 8/28/00 8:38 AM ~--. STATE OF ALASKA ....

The permit to ddll 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 Nodh Slope pager at 659-3607.
