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.

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. IreM 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). IreM 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. IreM 13: The API number reported to AOGCC must be 14 digits (ex: 50-029-20123-00-00). IreM 20: Report true vertical thickness of permafrost in Box 20. Provide MD and ND for the top and base of permafrost in Box 28. IreM 22: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. IreM 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). IreM 26: Method of Operation: Flowing, Gas Lift, Rod Pump, Hydraulic Pump, Submersible, Water Injection, Gas Injection, Shut-In, or Other (explain).

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). ' cerely, Daniel T.

The plan calls for a bighole lateral with a solid cemented liner in Zone 1 B/2A. Pre-Rig Work: 1. MIT-IA, and OA. 2. Dummy drift for 4-1/2" x 7" thru tubing WS to 9450 (29 deg incl) 3. Set 4-1/2" x 7" thru tubing whipstock @ 9400'. 4. Mill XN at 8595' to 3.80" with left handed motor, mill. 5. Squeeze 22 bbls of 15.8ppg cement past 4-1/2"x7" through tubing whipstock, to shut off perfs. (10 bbls into perfs, 6.66 bbls between bottom perf and WS and 5 bbls excess) 6. AC-LDS; AC-PPPOT- T. 7. Test MV, SV, WV. 8. Bleed gas lift and production flowlines down to zero and blind flange. 9. Remove wellhouse, level pad. The pre CTD work is slated to begin on November 19, 2008. Rig Work: 1. MIRU and test BOPE to 250 psi low and 3500. psi high, Pull BPV if installed. 2. Mill 3.80" window at 9400' and 10' of openhole. Swap the well to Flo-Pro. 3. Drill build/turn section with 3-3/4 x 4-1/8" bicenter bit, and land well. 24deg/100 (plan #2). 4. Drill lateral section with 3-3/4 x 4-1/8" bicenter bit to TD at 11060'. 12 deg/100 (plan #2). 5. Run 3-3/16" by 2-7/8" solid/ cemented liner leaving TOL at 8580' and cross over form 3- 3/16" to 2-7/8" at 10400'. 6. Pump primary cement job up to 9150' (leaving room for future sidetrack below 9-5/8" shoe at 8840'), 24.5 bbl of 15.8 ppg cmt planned. 7. Run CO assembly. 8. Run MCNVGR/CCL log. 9. Test liner lap to 2000 psi. 10. Perforate, planned 800'. 11. Freeze protect well, Set BPV, RDMO Post-Rig Work: 1. Pull BPV 2. Re-install wellhouse and FL's. 3. Generic GLV design. 4. Flow well to portable test separator. Mud Program: • Well kill: 8.6 ppg brine • Milling/drilling: 8.6 ppg Flo Pro or biozan for milling, new Flo Pro for drilling. h~`7 ~~~~~- Disposal: • All drilling and completion fluids and all other Class II wastes will go to Grind & Inject. • All Class I wastes will go to Pad 3 for disposal. Hole size: 4-1/8" Casing Program: • 2 7/8", 6.4# , L-80, STL solid liner: 11,060'-10,400' MD. • 3-3/16", 6.2#, L-80, TC-II solid liner: 10,400'-8,580' MD. • A minimum of 24.5 bbls 15.8 ppg cement will be used to cement the solid liner. • TOC planned at 9,150' . Well Control: • BOP diagram is attached. • Pipe rams, blind rams and the CT pack off will be pressure tested to 250 psi and to 3500 psi. • The annular preventer will be tested to 250 psi and 2500 psi. Directional • See attached directional plan. Max. planned hole angle is 90 deg. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property - 25,000' to North. • Distance to nearest well within pool - 800' ft to C-09A. Anticollision Summary • With Global Scan Applied all wells in area pass major anti-collision. Logging • MWD directional, Gamma Ray and Res. will be run over all of the open hole section. • MCNL will be run in cased hole section. Hazards • The maximum recorded H2S level on C-Pad is 25 ppm on C-04B. • There is one planned perpendicular fault crossings with 10' throw near 9,950' in Zone 1B. This area of the field does have moderate potential for losses, but this well is considered a low risk for losses. Reservoir Pressure • Res. press. is estimated to be 3,234 psi at 8,800'ss (7.07 ppg EMW). Maximum surface pressure with gas (0.10 psi/ft) to surface is 2354 psi.

Datum Drilling Measured From Elevation of Kelly Bushing Elevation of Derrick Floor Elevation of Ground Level ~d~~~~~ ~~~~~ tapescan.txt CASE.F N/A Casing Depth OS1 DIRECTIONAL Other Services Line 1 Remarks (1) All depths are Measured Depths (MD) unless otherwise noted. (2) All depths are Bit Depths unless otherwise noted. (3) All True vertical Depths (TVDSS) are Subsea corrected. (4) All Formation Evaluation data is realtime data. (5) Baker Hughes INTEQ utilized CoilTrak downhole tools and the Advantage surface system to lob this well.. (6) Tools ran in the string included Casing Collar Locator, an Electrical Disconnect and circulating sub, a Drilling Performance sub (Inner and outer Downhole Pressure, vibration and Downhole weight on Bit), a Directional and Gamma Sub, and a Hydraulic orienting Sub with a Near Bit Inclination Sensor. (7) Data presented here is final and has been depth adjusted to a PDC (Primary Depth Control) log provided by Schlumberger GR CNL dated 04 Dec 2008 per Doug Stoner with BP Exploration (Alaska), Inc. (8) The sidetrack was drilled from C-30 through a milled window in a 7 inch liner. Top of window 9403 ft.MD (8825.7 ft.TVDSS) Bottom of window 9411 ft.MD (8832.7 ft.TVDSS) (9) Tied to C-30 at 9379.6 feet MD (8805.2 feet TVDSS). (10) The resistivity tool was picked up after TD so all resistivity data presented is Mad Pass data. (11) The interval from 11033 feet to 11060 feet MD (8968.5 feet to 8968.7 feet TvDSS) was not logged due to sensor to bit offset at well TD.
