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, Gerald Murphy, at 659 -5102. Sincerely, Mehreen Vazir BPXA, Well Integrity Coordinator • 0 BP Exploration (Alaska) Inc.

ITEM 1a: Classification of Service Wells: Gas Injection, Water Injection, Water-Alternating-Gas Injection, Salt Water Disposal, Water Supply for Injection, Observation, or Other. Multiple completion is defined as a well producing from more than one pool with production from each pool completely segregated. Each segregated pool is a completion. ITEM 4b: TPI (Top of Producing Interval). ITEM 8: The Kelly Bushing elevation in feet above mean low low water. Use same as reference for depth measurements given in other spaces on this form and in any attachments, ITEM 13: The API number reported to AOGCC must be 14 digits (ex: 50-029-20123-00-00). ITEM 20: True vertical thickness. ITEM 22: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. ITEM 23: If this well is completed for separate production from more than one interval (multiple completion), so state in item 1, and in item 23 show the producing intervals for only the interval reported in item 26. (Submit a separate form for each additional interval to be separately produced, showing the data pertinent to such interval).

If losses/breathing is encountered, consult the Lost Circulation Decision Tree regarding LCM treatments and procedures and adjust drilling practices as necessary to reduce losses. A PWD is being run in the intermediate hole section to monitor hole cleaning and drilling practices. ).- Cretaceous overpressure was noted on the North side of the pad in wells P-24 and P-25 in 1997. The cretaceous interval required a 10.4 ppg mud weight to stabilize. ).- P Pad has a history of wellbore stability problems within the Kingak shales, particularly when faults were crossed in the Kingak. Stuck pipe incidents are noted on the pad data sheet. Correct selection of mud weight is critical to ensure Kingak shale stability. Problems have been encountered in both high and low angle wells, however high angle wells have been most problematic. Follow all shale drilling practices to limit high ECD's, and maintain proper mud weights and shale stabilizers in the drilling fluid ).- A mud weight of 11.1 ppg has been picked for drilling the Kingak portion of the intermediate hole. This is based on the inclination and azimuth applied to the Kingak Polar Plot. ).- KICK TOLERANCE: In the case scenario of 8.4 ppg pore pressure at the Top Sag River target depth (8885' tvd), gauge hole, a fract~:"~. .,e' radient of 12.5 ppg at the surface casing shoe, 11.3 ppg mud in the hole the kick tolerance is ~Dbls. An accurate LOT will be required as well as heightened awareness for kick detection. Contact Drilling Manager if LOT is less than 12.0 ppg. ).- Extreme care should be taken when picking the 7-5/8" casing point - Top Sag River. Lost circulation may be seen when the Sag River is penetrated with the 11.3 ppg intermediate hole mud. ~ There are no "major risk close approach" issues with the intermediate hole section of P-27.

The tail slurry will cover the shoe to 600' above the Top Sag and the tail will cover from 600' above the Top Sag to 500' above the UG1 interval. >- Several instances of packing off, stuck casing and the inability to reciprocate during cement jobs has occurred on P Pad. The SV and Ugnu sands will be exsposed to significant differential pressure. Lessons learned indicate that every attempt should be made to condition the hole and wiper trip sufficiently prior to running casing, ensure very tight fluid loss properties of the mud and that during casing running every effort must be made to keep the pipe moving. A casing running program will be jointly issued by the ODE and Drilling Supervisor detailing circulating points and running speed. In addition a LCM pill composed of "G Seal" may be placed across the WS and Ugnu to help arrest mud dehydration if losses were experienced while drilling this interval > Ensure the lower production cement has reached at least a 70BC thickening value prior to freeze protecting. Pump approximately Y2 volume of casing-casing annulus prior to freeze. After freeze protecting the 7-5/8" x 10-314" casing outer annulus with 63 bbls of dead crude (2200' MD, 2100'TVD), the hydrostatic pressure will be 7.7 ppg vs 8.5 ppg EMW of the formation pressure immediately below the shoe. Ensure a double-barrier at the surface on the annulus exists until the cement has set up for at least 12 hours. Reference RPs .:. "Intermediate Casing and Cementing Guidelines" .:.

Losses have ranged from minor to severe (-34,000 barrels). All cases of severe losses have been fault related and were managed by pumping fiberous/carbonate LCM pills. Be prepared for losses by establishing a contingency plan and consulting the Lost Circulation Contingency plan attached. >- The East and West sides of the target polygon are bounded by faults The target polygon hardline is designed to maintain 150' standoff from these regions. >- There are two "potential" faults in the production hole section at 15,930' and 17,560' MD. Both have 10' of throw. }> The kick tolerance is Ge for the 6-3/4" open hole section assuming a kick from Zone 4B at -8,950' TVD ss.

The FloPro will be approximately 200 psi over balance to the Ivishak formation. Minimize the time the pipe is left stationary while running the liner. ~ In the event additional weight is required to get the liner to TD, have 6 stands of weight pipe in the derrick. ~ A liner inner string should not be required to help convey the liner to bottom. An inner string contingency however is included should open hole conditions be poor. ~ Keep in mind that the Ivishak interval will be open during liner running. Avoid introducing lighted than 8.6 ppg completion brines during swap over. Reference RPs .:. "Running and Cementing a Liner Conventionally" Job 12: Run Completion Hazards and Contingencies ~ Keep in mind that the production interval will be open during the running of the completion. Watch hole fill closely, verify no light fluids are introduced down hole and verify proper safety valves are on the rig floor while running this completion. ~ Shear valves have been failing at lower than the 2500 psi differential pressure. When testing annulus maintain no more than a 1500 psi differential. Avoid cycling pressure (pumping up and bleeding off) prior to activating shear valve as this is thought to cause shearing at lower pressures. ~ Review requirement for second barrier when freeze protecting well.
