Terrie Hubble, 564-4628 Well Number Permit No. / Approval No. Drilling Engineer: Abby Warren, 564-5720 INSTRUCTIONS General: This form is designed for submitting a complete and correct well completion report and log on all types of lands and leases in Alaska. 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 la: 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 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 23: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. Item 24: 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). Item 27: Method of Operation: Flowing, Gas Lift, Rod Pump, Hydraulic Pump, Submersible, Water Injection, Gas Injection, Shut -In, or Other (explain). Item 28: Provide a listing of intervals cored and the corresponding formations, and a brief description in this box.

The reason to cut it and not rerun it is if it is left in there and a new 7" casing string is run, this turns the annulus into an OOA. Per BP's policies on operating pressures, an OOA has a lower operating pressure than that of the OA. So by removing the 9 -5/8" at -2200' we are removing an annulus and in turn keeping the same operating pressures as before. Please let me know if you have any questions.

This permit to drill does not exempt you from obtaining additional permits or an approval required by law from other governmental agencies and does not authorize conducting drilling operations until all other required permits and approvals have been issued. In addition, the Commission reserves the right to withdraw the permit in the event it was erroneously issued. Operations must be conducted in accordance with AS 31.05 and Title 20, Chapter 25 of the Alaska Administrative Code unless the Commission specifically authorizes a variance. Failure to comply with an applicable provision of AS 31.05, Title 20, Chapter 25 of the Alaska Administrative Code, or a Commission order, or the terms and conditions of this permit may result in the revocation or suspension of the permit.

During rig operations, the 9 -5/8" casing will be cut and pulled due to IAxOA communication and will not be rerun. The whipstock exit from the 9 -5/8" casing is estimated at 8400' MD and will be milled using an 8 -1/2" milling - assembly. The 8 -1/2" hole will be drilled to the Top of the Sag River where a 7" casing will be run to surface and cemented above the cretaceous leak in the 9 -5/8" casing. The production hole will be drilled with a 6 -1/8" BHA building to horizontal. The well will then run horizontally through the Ivishak formation. The liner will be a 4 -1/2" 13Cr liner and the tubing will be 4 -1/2" 13Cr, tied into the top of the production liner.

Annular test to 2,500 psi /250 psi Integrity Test — 6 -1/8" hole FIT /LOT after drilling 20' of new hole Planned completion fluids 8.5 ppg Seawater / 6.8 ppg Diesel Other Requests: Given rig floor height limitations, a MASP < 3000 psi, and the fact that the three ram drilling BOP configuration is preferred to a two ram configuration with a spool, BPXA will execute the provisions of 20 AAC 25.285 (f) (1) regarding the initial testing of the BOPE as follows when existing wellhead or testing equipment prevents the testing of the lowest set of pipe rams: That lowest 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. Safety concerns and spacing limitations with the wellhead height and tubing spool preclude us from installing a spacer spool in the three -ram drilling 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. 17 -09A Permit to Drill Application Page 6 Drillifi Hazards and Contin *ncies POST THIS NOTICE IN THE DOGHOUSE I. Well Control A. The Ivishak in this fault block is expected to be 8.0 ppg EMW. This pressure is estimated based on offset well pressures. 3500 psi test pressure is in accordance with the RP for Prudhoe production well casing tests for producing wells. II. Lost Circulation /Breathing A. 17 -09A has a low risk of LC due to the seismic data which indicates that we have one small fault crossing in Z4 in the lateral part of the sidetrack. B. There is two major LC events on DS 17, both wells are west of the 17 -09A targets. 17 -19A (1997) lost +/ -6000 bbls after crossing a fault in the shublik and 17 -03 (1998) lost +/ -5000 bbls after crossing a fault in Zone 4. III. Kick Tolerance /Integrity Testing A. With the planned mud weights, the kick tolerance for the intermediate section is infinite, and for the production section is infinite. The FIT /LOT will prove up adequate formation strength for expected ECD's. B.

Hydrogen Sulfide A. 17 -09 has had a maz reading of 50 ppm and the most current reading (2006) was 40ppm The highest recorded H2S level on the pad was 160 ppm on 17 -04 (7/02/07) V. Faults A. One fault crossing is expected in Zone 4 but the fault is very small and we are crossing in Z4. Minimal - LC issues are expected. VI. Anti - Collision Issues A. All wells pass major risk criteria except for 16 -29. 1 6 -29 /as the original wellbore which was never completed. and it was automatically re- drilled after Ic5'g was run there was cement laid in 16 -29 and the well was renamed 16 -29A.
