C011Nni~gion Anchoraga a,o~ ~ ~ ~~ ~- ~ ~~ Enclosed please find multiple copies of a spreadsheet with a list of wells from GPB L- 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.

Blo,vout prevention equipment (BOP E) must be tested in accordance with 20 AAC 25 035. Sufficient notice (approximately 24 hours) must be given to allow a representative of the Commission to witness a test of BOPE installed prior to drilling new hole.

AOGCC Date: February 14, 2002 From: Robert S.Odenthal Subject: Dispensation for 20 AA C 25.035 (c) on L-I02 BP Alaska Drilling alld H'ells requests your consideration of a waiver of the diverter system identified in 20 AAC 25.035 (c) "Secondary Well Control for Prinlary Drilling and Completion: Blo\vout Prevention Equipment and Diverter Requirements". Experience and data gathered. summarized herein. support the rationale for the request. To date. none of the 9 Borealis/Ivishak wells at L-pad. nor the two NWE wells 1-0 I and 1-02 drilled in 1998 experienced pressure control or shallow gas problems above the surface casing depth, apart from minor and inconsequential hydrate sho\vs. All six of the surface holes for the Borealis Development (L-116, L-II O. L-114, L-115, L-I 06.L-I 0-1-. L-I07 and L-120) and the first Ivishak well (L-O 1) were drilled to the shale underlying the SV -1 sands. The shale underlying the SV 1 is the deepest planned surface casing setting depth for future pad development wells. This casing point is :t300' TVD above the Ugnu horizon. RFT's from NWE 1-02 recorded pore pressures of 1.275 psi at 2782' TVDss (8.8 ppg EMW) and 1387 psi at 3059' TVDss (8.7 ppg EMW) in the Ugnu. L-Ill is planned to reach a 9.5 ppg mud weight before TO at 2,676' TVDss. This request is being made based on L-Pad data subnlitted regarding mud weight. gas monitoring. recent open hole surface logging of L-I06 (PEX/Dipole sonic) and meeting between Jack Hartz. Robert Crandall. Steve Davies. Bob Dawson (BP), Ray Eastwood (BP) and Kip Cerveny (BP). Your consideration of the waiver is appreciated. Sincerely, ~ - ~ I ' '----~t;h--+'5 V~ Robert S.
