So I think that is the last detail you needed on this one.

I'll note the change on my copy. The Cement Report for the 7" slurry (Lead) says the Yield was 3.52. I'll copy our cementing expert on this note so that he can respond to us if that is incorrect. John Rose will need to respond to you regarding the BOP rams.

Was 8-1/2" or 8-3/4" hole drilled? 2. What was the yield for the 7" lead slurry? I calculate 3.51, but the permit to drill listed 1.61. 3. Was the BOP equipped with 2-7/8" rams for the perforating string? Thanks in advance.

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. When providing notice for a representative of the Commission to witness any required test, contact the Commission's petroleum field inspector at (907) 659-3607 (pager). Sincerely, Cath P.

The plan is to exit the parent F-33 wellbore from a balanced cement plug at 3590' MD. The 8-1/2' hole will be drilled to the Top of the Sag River where a 7" intermediate casing string will be run to surface and cemented up to 200' below the 10-3/4" casing shoe. The production hole will be drilled building to horizontal in the Ivishak Zone 4 to a final TD of ~ 12,624' MD where a solid liner will be run and fully cemented to TD. A 4-1/2' completion will then be run to complete the well. The F-33A sidetrack is currently scheduled for Nabors 7ES beginning January 2009.

Hydrogen Sulfide F-Pad should be considered an H2S site. Recent H2S data from the pad is as follows: H2S Well Name Level Date of Readin #1 Closest SHL Well H2S Level #2 Closest SHL Well H2S Level #1 Closest BHL Well H2S Level #2 Closest BHL Well H2S Level Max. Recorded H2S on Pad/Facility Other Relevant H2S Data (H2S alarms from rigs, etc.) F-23A 10 m 5/22/2007 F-42A No data F-19 No data F-36 20 m 10/6/2007 F-24 160 m 5/15/2007 F-33 H2S data is not available. The high H2S on F-Pad is found in the waterflood block. F-18 is in the waterflood block. Faults The F-33A wellpath is not expected to intersect any mapped faults. The proposed well is located in an area of generally E-W trending faults. Fault #1 is an E-W trending, ~20 ft, D to S fault located 250 ft south of the well path. Fault #2 is a short fault, with < 10 ft of D to N offset -- 150 north of the well plan. Fault #3 is another short fault, generally E-W trending, --15 ft, D to N fault located about 200 ft north of and generally parallel to the planned well path. Fault #4 is a generally E-W trending, 100 ft, D to N fault located about 500 ft north of the BHL. Fault #5 is a N-S trending, 30 ft, D to W fault located 450 east of the BHL. Fault #6 is a small (<10 ft), D to W fault located 350 west of the landing point. Well Control Well control equipment consisting of 5,000 psi working pressure pipe rams (2), blind/shear rams, and annular preventer will be installed and are capable of handling the maximum potential surface pressures. Based upon calculations below, BOP equipment will be tested to 3,500 psi. BOP regular test frequency for F-33A will be 14 days during drilling phase and 7 days during decompletion and surface casing work.

If the lower set of pipe rams cannot be tested during the primary BOP test, 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. Safety concerns and spacing limitations with the wellhead height and tubing spool 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. F-33A Permit to Drill Application Page 7 Drillin~Hazards and Contin~ POST THIS NOTICE IN THE DOGHOUSE I. Well Control A. The Ivishak in this fault block is expected to be under-pressured at 5.8 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. II. Lost Circulation/Breathing A. The F-33A wellpath is not expected to intersect any mapped faults. The proposed well is located in an area of generally E-W trending faults. Fault #1 is an E-W trending, -20 ft, D to S fault located 250 ft south of the well path. Fault #2 is a short fault, with < 10 ft of D to N offset ~ 150 north of the well plan. Fault #3 is another short fault, generally E-W trending, ~15 ft, D to N fault located about 200 ft north of and generally parallel to the planned well path. Fault #4 is a generally E-W trending, 100 ft, D to N fault located about 500 ft north of the BHL. Fault #5 is a N-S trending, 30 ft, D to W fault located 450 east of the BHL. Fault #6 is a small (<10 ft), D to W fault located 350 west of the landing point. B. This well is located in an area considered to have "Moderate" potential for Lost Circulation, according to the WURD study. Many of the wells in the immediate area have drilled through faults without noting losses. The closest well with significant LC was the F-37, located approximately 5200 ft SW of the BHL, which lost 7580 BBL into the Shublik (near the intersection of two mapped faults). Based on the available data, the F-33A should have average potential for Lost Circulation. Details of losses in the surroundino area are noted below: Well T e Loss bbls MD TVDSS Zone X LOC Y LOC E-29 ri 1000 11161 8405 Above Sa -LCU 658565 5976996 F-34A ri 22 10920 8627 Sa River 652948 5979395 F-37 ri 7580 10780 8633 Shublik 648449 5978495 F-42 ri 54 11650 9111 Below BSAD 651163 5980512 J-24A coil. 350 12475 8586 Sa River 646579 5976485 J-24A coil 550 12895 8604 Sa River 646921 5976263 J-24A coil 190 10938 8594 Shublik A 645288 5976197 III. Kick Tolerance/Integrity Testing A. With the planned mud weights, the kick tolerance for the intermediate section is 131 bbls, and that for the production section is infinite. The FIT will prove up adequate formation strength for expected ECD's. B. Integrity Testing Test Point Test De th Test a EMW Ib/ al 9-g/8' window 20-ft minimum from the 9 5/a" window FIT 12.2 minimum 7" shoe 20-ft minimum from the 7" shoe FIT 10.1 minimum IV. Stuck Pipe A. Significant directional work will be required in the production hole section. Hole cleaning and differential sticking tendency will be of concern. Watch for signs of tight hole and short trip /back ream as required to avoid stuck pipe. VI. Hydrogen Sulfide A. F-PAD is designated as an H2S site. F-33 H2S data is not available. H2S levels above the 100 ppm threshold have been recorded on this pad. VII. Faults A. The F-33A wellpath is not expected to intersect any mapped faults. See Section II on lost circulation for more details. VIII. Anti-Collision Issues A. All wells pass major risk criteria for close approach. F-34B is the closest well at 560' ctr-ctr.
