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). incerely, Daniel .

BOPE and drilling fluid system schematics are currently on file with the AOGCC. BOP regular test frequency for E-10B will be 14 days during drilling phase and 7 days during decompletion and surface casing work. Well Interval: 8'/i" intermediate interval Maximum antici ated BHP: 3,690 psi at 8,867' TVD Maximum surface ressure: 2,810 pSl (based upon BHP and a full column of gas from TD C~ 0.10 psi/ft) Calculated kick tolerance: Infinite Planned BOPE test pressure: 250 psi low / 3,500 psi high - 7 day test cycle until a window is milled in 9-5/8" casing. Once a window is milled a 14 day test cycle can commence. The VBR will not be changed to accommodate the 1,138-ft 7" drilling liner. Instead, the current and best practice of picking up a joint of drill pipe, with crossover to the casing thread, will be employed in the event of a kick. This practice provides two rams capable of closing on the pipe across the BOP stack instead of just a single 7". VBR will be changed before running the 7" tieback.

E-106 Permit to Drill Application Page 5 Faults Fault Details: E-10 B trajectory does not cross any mapped faults. The proposed E-lOB well will be located in northwestern E pad. No faults are expected to be encountered with the sidetrack. The structure in the vicinity of the proposed E-lOB well is moderately complex. The sidetrack location is west of the midfield graben and south of the E-K graben. There are a number of faults in the vicinity, including one regional fault just north and west of the E-lOB location. The polygon is relatively narrow however; as three additional faults are present 115 ft and 150 ft. south of the polygon and another is 70 ft north of the polygon edge. Near the end of the planned well a large regional east-west trending fault tips out 145 ft north of the polygon. The large throw of this fault may result in a larger than normal fracture zone around the tipout so it will be important to stay within the polygon near TD. The well cannot be extended because of the presence of a possible splay off the regional fault 180 ft west of the polygon. The proposed E-lOB well lies in a moderate risk province of the field for lost circulation at faults as documented by the WURD team. Eight loss circulation events were encountered in the Kingak and Ivishak section in 8 of the surrounding 18 wells as detailed below. Although no faults are expected to be encountered with the E- l OB sidetrack, the risk of loss circulation events is rated to be moderate because of the possibility of encountering fractures off of the regional fault to the north.

On the 7" liner volume, I did not include the amount above the liner top. That does make a difference. On the 7" tieback, it appears there was a typo in the sx count and it should be 842.

Would you check your cementing volumes for the 7" liner and tieback? I calculate a little short for the tieback, maybe I am not counting the collars and i am a little long for the liner. Just figuring 8.5 ID with 7" from TD to liner top, I calculate 84% XS. Please copy Jim Regg with your reply. If work needs to be done next week, he will do it.
