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, at 659-5102. Sincerely, Torin Roschinger BPXA, Well Integrity Coordinator BP Exploration (Alaska) Inc.

The wellhead pressures were tubing/IA/OA equal to SSV/2100/320 psi on 07/03/08. Due to the constraint of not being able to bleed pressure down to the production system due to the shut-down, the diagnostic work took longer to arrange and complete. On 07/11/08, a TIFL failed on overnight pressure increase confirming TxIA communication. The well has been reclassified as Under Evaluation and placed on a 28-day clock. Operations may allow the IA pressure to continue to increase or may continue to produce the well as Under Evaluation once the facility is returned to production. The plan forward for the well is as follows: 1. DHD: TIFL -FAILED 2. Slickline: Dummy gas lift valves 3. DHD: re-TIFL post dummy gas lift valves A TIO plot and wellbore schematic have been included for reference. 10/17/2008 OPERABLE: B-23A (PTD #1970590) tubing integrity has been restored Page 2 of 2 • • Please call with any questions.

As the attached AOGCC Safety Valve System Test Report shows I witnessed the testing of 17 wells and 34 components with 2 failures. The Pilot on well B-18 tripped below the required set point and the pilot on well B-21 was frozen. Both failures were repaired and sucessfully retested before I departed location. The new style pilot insulation box fabricated using pipeline insulation installed on most wells on this Pad shoUld be installed on the remaining SVS pilots to eliminate the freeze up problems evident on this pad. I also inspeCted the well houses on this pad While witnessing SVS testing. All the well houses inspeCted were clean and the equipment appeared to be in good condition.

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. Blowout prevention equipment (BOPE) 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. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607.

The objective of the redrill is to access Zone 2C and 2B reserves from a nearly horizontal wellbore about 1400' from the existing wellbore. Please confirm with the Rig Supervisor for the exact rig move schedule. Wireline and PE work to prepare the B-23 well before the rig move should be charged to AFE # 4P0929. Objective: The objective of pre-rig work activity is to prepare for P&A operations with the rig, and to cut the existing tubing (4-1/2") in preparation for tubing removal. The well will be freeze protected following pre-rig activities to prevent freeze damage. Pre-Rig Operations: 41.66' _Note: original KBE was 77.16', BF elevation is 1. Notify an AOGCC representative prior to beginning operations. 2. Check and service the wellhead, pressure test the 9-5/8" packoff to 3500 psi. o Kill the well with seawater, pull the SSSV if it is installed. Make a chemical cut of the 4-1/2" tubing at 9790' (just above the K-22 anchor). Make a tubing punch (4SPF) of the 4-1/2" tubing at 8700' (just below the 9-5/8" HB packer) NOTE: The minimum ID reported is 3.813" in "X" nipples located at 8640', 9808' and 9815'. The remaining "XN" profile presently has a plug set and is covered in fill (plug at 9864', top of fill at +9830' 4. Pull the GLM at 8621' to provide an open mandrel. . Ensure the well is dead and loaded with seawater then freeze protect to 2000' with diesel. Bleed off all pressure, set a TWC in the tubing hanger and test to 500 psi against TWC. Secure well. o Remove the well house and flowlines. Level the pad and dig out the cellar. Please provide total well preparation cost on the handover form.

Pull the 4-1/2" tubing from the PBR at 8647'MD. Inspect the tubing for NORM. Contact Baker for a fisherman and pull the Baker HB retreivable 9-5/8" packer and straddle down to the tubing cut at 9790'MD. PU 3-3/4" mill and 3-1/8" DC's (100' of BHA), wash down through fill to the plug in the "XN" nipple. The top of fill is _+9830', plug at 9864'. Circulate several hivis sweeps to clear the hole.
