Commi~~io~ Anchorag~ a~~ ~~s~ ~~ ~~ 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.

Winton Aubert AOGCC 793-1231 Kolstad, Scott R wrote Winton, As discussed, for well L-51 the primary cement job for the 7" intermediate casing string was performed in 2 stages with losses during the entire cement job. From a USIT -og we determined the TOC to be 5,400'. The planned TnG to satisfy the AOGCC 20 AAC 25.030 d.5 regulation was 3,500' (this is 500' above the sl-;a.liowist hydrocarbon zone, the Ma formation). The log shows cement channeling up to 2,800' and it may € got be possible to pump cement below 2,800'. In an attempt to gain cement isolation between the Ma and surface we are planning an OA down squeeze consisting of 25 bbls of 15.8 ppg class G cement. This volume may be adjusted based on infectivity ability. `~`Je request approval for this to satisfy the regulation noted above. There is currently one Kuparuk injector w/i 1/4 mile of L-51, L-115. L-51 cement job did achieve isolation above and below the Kuparuk reservoir. ~:,r the Schrader 131uff interval, there are currently no wells injecting w/i 1/4 mile of the L-51 penetration. rteyart~s, ~^cat H:olstad 1 of 1 6/29/2006 2:39 PM } ~ ~ ~,~ { ~ ~ i ~ ~ ~~ ~ ~ ' 1 ~ ~ \~ ~ ~ ~ ~~ ~, , , ~ ~ ! ~ , 1 , ; ~ FRANK H.

Revised 12/2005 Submit In Duplicate Variance Request Issue Compliance with AOGCC testing requirements for BOP rams after they have been used in the normal coarse of operations. Re uest The AOGCC is in the process of developing a guideline document clarifing the intent of the regulations pertaining to function pressure testing ram type BOP's. BPXA requests a variance #o the provisions of 20 AAC 25.035 (e)(10}C regarding the function pressure test requirement after the use of BOP ram type equipment for other than well control or equivalent purposes, except when the routine use of BOP ram type equipment may have compromised their effectiveness. (Example would be when pipe rams are inadverten#ly closed on a tool joint during routine operations.} The activities associated with this request will not compromise the integrity of the BOP equipment. Background AOGCC regulations require rams that have been used in the course of primary drilling & completion, workover and through tubing drilling operations be function pressure tested before the next wellbore entry. This is not a new regulation. The intent of this regulation is to ensure that ram type equipment has integrity after i# has been utilized in a wellbore...for example; to ensure integrity if a ram was closed on a tool joint. The exact reguiatian language is: "if BOP sealing ram type equipment has been used, it must be function pressure-tested, before the next wellbore entry, to the required working pressure specified in the approved Permit #o Drill, using anon-compressible fluid, except that an annular type preventer need not be tested to more than 50 percent of its rated working pressure;" The pertinent sections are: 20 AAC 25.035 (e)(10)C PRIMARY DRILLING AND COMPLETION; 20 AAC 25.036 (d}(4) THROUGH TUBING DRILLING AND COMPLETION; 20 AAC 25.285 (f)(2} TUBING WORKOVERS• 20 AAC 25.286(e){1) WORKSTRING SERVICE OPERATIONS This issue has been discussed with Winton Aubert at the AOGCC. The test requirement in the regulation is intended to apply to ram tyt~e eauipment only. The AOGCC understands that ram type BOP's are utilized for purposes other than well control in the normal coarse of operations. The regulations allowing a variance are at 20 AAC 25.035(h) PRIMARY DRILLING AND COMPLETION; 20 AAC 25.036{f) THROUGH TUBING DRILLING AND COMPLETION; 20 AAC 25.285(h} TUBING WORKOVERS; 20 AAC 25.286(g} WORKSTRING SERVICE OPERATIONS...which says generally: 20 AAC 25.035(h)... Upon request of the operator, the commission will, in its discretion, approve a variance (1) from the ROPE requirements in (e) of this section if the variance provides at least an equally effective means of well control; • • Well Name: L-51 Drill and Complete Plan Summary T e of Well service / roducer / in'ector : Producer Surface Location: X = 583,057.9' Y = 5,978,062.76' As-Staked 2342.5' FSL, 1420.6' FWL ,Sec. 34, T12N, R11 E Target Locations: X = 581,387' Y = 5,982,192' TO Sa River: 1210.7' FSL, 196.5' FEL ,Sec. 28, T12N, R11 E Bottom Hole Location: X = 581,245' Y = 5,987,490' 1230.4' FSL, 269.5' FEL ,Sec. 21, T12N, R11 E ~' AFE Number: PBDxxx Ri Nabors 7ES - Estimated Start Date: 5/15/06 MD: 15,686' TVD: 8,896' O eratin da s to com lete: 29 RT/GL: 28.5' RKB: 76.4'; Well Design Conventional, slimhole, etc.): Ultra Slimhole Horizontal ~ ,~ Ob'ective: Producer in the Sa River formation.

Gas Hydrates are expected at L-pad near the base of the permafrost. Setting casing through the SV1 should keep hydrate exposure from extending past the surface hole. Recommended practices for drilling hydrates should be followed in the surface hole. Occasionally hydrates are encountered below the SV1. III. Lost Circulation /Breathing: A. Lost circulation risk is considered moderate to high within the horizontal section and throughout the uphole intervals. B. The Shublik in not planned to be penetrated, but well bore breathing could occur if it is. IV. Kick Tolerance /Integrity Testing: A. The 9 5/a" casing will be cemented to surface. The 7" casing will be cemented to 500' MD above the Ma sand. B.

A heightened awareness of kick detection, pre-job planning and trip tank c ' ~ ation will be essential while drillin tri in the intermediate/ roduction intervals. V. Stuck Pipe A. There could be differential sticking across the Schrader Bluff while running the 7" casing. Keep the casing moving as much as possible and follow the centralizer program to help with standoff. VI. Hydrogen Sulfide A. L Pad is nQ,designated as an HZS site, however Standard Operating Procedures for HZS precautions should be followed at all times. No measurable HZS is being produced from the formation at this time. However 10 ppm is measured regularly at L pad as a result of the use of Ivishak gas lift gas. All L pad gas lift wells will likely have HZS in this concentration. Note that all injection has been with produced water not seawater. HZS levels are expected to remain low until the water flood matures.
