Colr~~~lp~ Anchorage aos-!4 z-o~A Enclosed please find multiple copies of a spreadsheet with a list of wells from GPB Z- 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.

Submit a well schematic diagram with each 10-407 well completion report and 10-404 well sundry report when the downhole well design is changed. ITeM 1a: Classification of Service Wells: Gas Injection, Water Injection, Water-Alternating-Gas Injection, Saft 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 and Ground Level elevation in feet above mean sea level. 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: Report true vertical thickness of permafrost in Box 20. Provide MD and TVD for the top and base of permafrost in Box 28. 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 addltional interval to be separately produced, showing the data pertinent to such interval). ITeM 26: Method of Operation: Flowing, Gas Lift, Rod Pump, Hydraulic Pump, Submersible, Water Injection, Gas Injection, Shut-In, or Other (explain). ITeM 27: Provide a listing of intervals cored and the corresponding formations, and a brief description in this box. Submit detailed description and analytical laboratory information required by 20 AAC 25.071.

Tom Maunder, PE AOGCC From: Kolstad, Scott R [maifto:Scott.Kolstad@bp.com] Sent: Tuesday, October 07, 2008 2:18 PM To: Maunder, Thomas E (DOA) CC: NSU, ADW Drlg Rig 9es; Sayers, Zach J; Ciolkosz, Ryan R; Tirpack, Robert B Subject: Change of scope for Z-09A 308-307 and 2081410 Tom, We encountered operational difficulties while trying to recover the original production packer from Z-09. The original plan was to mill this packer and complete a single string sidetrack. During the decompletion operations we discovered the lower part of the 3 1/2" tubing string and packer are sanded in. We've made two fishing attempts to retrieve the SBR and pulled the 3 1/2" tubing apart on the last attempt. We believe the chances of successfully recovering the packer are very low. At this point we would like to stop fishing operations and turn this into a two sting sidetrack. We plan to set a whipstock in the 9 518" casing, drill to the top of the Sag, and run a 7" liner. From this point we will be back on plan. Please see below for operations to date and planned operations. We are still working up directional plans, schematics, etc. We can provide these when they are completed. R~ Operations: 1. MIRU. 2. Pull BPV. Circulate out freeze protection and displace well to 9.4 ppg brine. 3. Monitor OA, IA and Tubing for pressure and tested both to 3,500 psi. 4. Set TWC. Nipple down tree. Nipple up and test BOPS. Pull TWC. 5. Attempted to Pull 3-1/2" TDS tubing (spooling SSSV control lines) from pre-rig cut. 6. Unable to pull tubing from first cut. Made second cut in the tubing. 7. Pull and retrieve tubing from 1st cut. 8. Fish out 3' piece from second cut. 9. Attempt to release latch from packer and fish SBR. Unsuccessful. 10. Second attempt to fish SBR. Parted the 3 '/2" tubing above the packer. Tubing and packer are sanded in. 11. Decide to sidetrack out of the 9 5/8" casing. 12. Make 9 5/8" casing scraper run. 10/7/2008 Change of scope for Z-09A 3007 and 2081410 C~ Page 2 of 3 13. RU eline and set 9 5/8" CIBP to place the new kick off point in the Kingak JD. This CIBP will be part of the permanent abandonment for the Z-09 well. 14. Change out 9-5/8" Packoff 15. PU 9 5/8" Baker bottom trip whipstock assembly. RIH, orient whipstock and set on CIBP. 16. Swap over to LSND milling fluid. 17. Mill window and 20' of new formation. 18. Perform FIT test to 12 ppg. 19. Drill 8 %2" hole to the top of the Sag River formation. 20. Run and cement a 7" liner with 150' liner lap. The liner lap cement will serve as part of the Z-09 permanent abandonment. 21. MU 6.125" build BHA with Dir/GR/RES on 4" DP and RiH to window. 22. Drill the 6.125" build section to landing point. 23. TOH to change motor bend, bit, and PU Den/Neu tools (recorded mode only) 24. Log USIT in cement and corrosion mode in the 7" liner and 9-5/8" casing from as deep as possible to surface. This log will be used to determine the cement isolation from the reservoir for injection purposes. 25. Drill production interval, targeting Zone 3 & 4 of the Ivishak. 26. Run and cement a 4-1/2" solid liner throughout the 6.125" well bore and back into the 7" casing. Set liner top packer and displace well to 9.1 ppg brine above the liner top. 27. RIH with DPC pert guns. Perf intervals +/- 150' to be determined from LWD logs. Plan to perforate overbalance. POOH, LD DP and pert guns. 28. Run the 4-1/2", 12.6#, L-80 completion, tying into the 4-1/2" liner top. 29. Assuming no GLMs are run, freeze protect tubing and IA to 2,200' TVD with diesel. 30. Set packer and test the tubing to 4,000 psi and annulus to 4,000 psi for 30 minutes. 31. Set and test TWC. 32. ND BOPE. NU and test the tree to 5,000 psi. 33. Secure the well. 34. RDMO. Post-Rica Work: 1. Install well house and flow lines. 2. MIRU slick line. Pull the ball and rod / RHC plug from `XN' nipple below the new production packer. 3. Install gas lift valves.

"L ~ BPXA requests a variance to the provisions of 20 AAC 25.035 (e)(10)(A) regarding the initial testing of the BOPE when installed as follows: If the lower set of pipe rams cannot be tested during the primary BOP test (due to the proximity to the test plug) that set of rams will be tested at the earliest opportunity during path-forward de-completion work, i.e., after the completion has been pulled from the well. Spacing limitations with the wellhead height and tubing spool might preclude us from installing a spacer spool in the BOP stack. Disposal • No annular injection in this well. • Cuttings Handling: Cuttings generated from drilling operations will be hauled to grind and inject at DS-04. Any metal cuttings will be sent to the North Slope Borough. • Fluid Handling: Haul all drilling and completion fluids and other Class II wastes to DS-04 for injection. Haul all Class I waste to Pad 3 for disposal. Z-09A Permit to Drill Application Page 5 DrillinT Hazards and Conting'~ncies POST THIS NOTICE IN THE DOGHOUSE I. Well Control A. The Ivishak in this fault block is expected to be normally-pressured at 8.2 ppg EMW. II. Lost Circulation/Breathing A. The Z-09A is expected to intersect one small fault (Fault #1) present before the final drop to the perforation intervals in the Ivishak. Fault #1 has a small (~10 ft) vertical throw. It is orientated in NW - SE direction. Due to this fault's very small lateral extent and small displacement, lost circulation should not be a major concern; likely an occurrence, but small in magnitude. III. Kick Tolerance/Integrity Testing A. The Kick Tolerance for the mill window and production hole sections is infinite with planned mud weights. B. Integrity Testing _Test Point i Test Depth ~ Test type EMW (Ib/gal) 7" window ~ 20-ft minimum from the 7" window FIT ~ 10.5 minimum IV. Stuck Pipe A. No abnormal stuck pipe risks have been identified for this well. VI.
