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 MITIA failed after setting dummy aas lift valves although there was no clear indication of TxIA communication. A leak was noted at the downhole control vavle nipples so work continues to change out the nipples. The well will then be evaluated for a leak detection log.

A June 3, 2008 DS 06-23C- Coiled Tubing ling Mud Program: • Well kill: 8.6 ppg brine • Milling/drilling: 8.6 ppg Flo Pro or biozan for milling, new Flo Pro for drilling. Disposal: • All drilling and completion fluids and all other Class II wastes will go to Grind & Inject. • All Class I wastes will go to Pad 3 for disposal. Hole size: 3" Casing Program: • 2 3/8", 4.7# , L-80, STL connection Solid liner - 8675'MD - 11,550' M w/liner top packer. • A minimum of 8 bbls 15.8 ppg cement will be used for liner cementing. (TOC 9100'MD) Well Control: • BOP diagram is attached. • Pipe rams, blind rams and the CT pack off will be pressure tested to 250 psi and to 3500 psi. • The annular preventer will be tested to 250 psi and 2500 psi. Directional • See attached directional plan. Max. planned hole angle is 90 deg. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property - 18,500' (South) Anticollision Summary • 06-01 - 908' ctr-ctr, Status: Producing • 06-03A - 1196' ctr-ctr, Status: Producing • 06-03A - 1208' ctr-ctr, Status: Producing • 06-05 - 1281' ft ctr-ctr, Status: Shut in Logging • MWD directional, Gamma Ray, and Resistivity will be run over all of the open hole section. • A cased hole GR/CCVCNL log will be run. Hazards • The maximum recorded H2S level on DS 6 is 200 ppm on 06-08A(05-15-2006). DS 6 is an H2S pad; H2S procedures will be followed. • Lost circulation risk is low. Only one small fault crossing is expected and it was crossed in the parent well with no issues. Reservoir Pressure • Res. press. is estimated to be 3,269 psi at 8,800'ss (7.1 ppg EMW). Maxi um surface pressure with gas (0.10 psi/ft) to surface is 2381 psi. ~~'t~G Mel Rixs~~~~ CTD Drilling Engineer June 3, 2008 WELLHEAQ= FMC ACTUATOR = AXELSON KB. ELEV = 74' BF.
