Sondra Stewman,564-4750 Well Number Permit No./Approval No. Drilling Engineer: Cody Hinchman, 564-4468 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 1 a: 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 ND 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. Submit detailed description and analytical laboratory information required by 20 MC 25.071. Item 30: Provide a listing of intervals tested and the corresponding formation,and a brief summary in this box. Submit detailed test and analytical laboratory information required by 20 MC 25.071.

Well 18-10B was sidetracked in March 2002 after well 18-10A gassed out. The well is a Zone 1A horizontal in the northwest area of DS 18. It was completed with 1176' of 2-7/8" slotted liner. After several years at a sustained production rate the rate leveled out and the GOR increased until it exceeded MGOR. The well became a swing well and on-time declined. In 2009,the well was shut-in most of the year due to high GOR and competition from its twin well 18-09B. Well 18-10B was brought back on in December 2009 and had to be shut-in shortly after on March 1, 2010 due to the GOR increasing and the oil rate falling off. The well has remained shut-in since March 1,2010. Since the well has a slotted liner,the gas shut-off options are limited. The well has a passing MIT-T,MIT-IA and MIT-OA. The proposed plan for well 18-10C is to sidetrack out of the 18-10B 3-3/16"production liner with the Nordic 1 Coiled Tubing Drilling rig on or around Sept. 10,2010. The existing perforations will be isolated by the pre-rig set packer whipstock set at 12,250' MD and the primary cement job after drilling and running liner. The sidetrack will exit the 3-3/16"liner in Z2A and drill a 3"hole in the target Z1A sands. CTD Sidetrack Summary Pre-Rig Work: (scheduled to begin August 21, 2010). 1. S Dummy GLV's 2. S Pull 4-1/2" KB LTP at 11,997' MD. 3. S Dummy WS drift to 12,270' MD. 4. E Set 3-3/16"Baker packer whipstock 30°ROHS at 12,250' MD. 5. F PT packer whipstock to 1000 psi for 30 min. 6. W AC-LDS; AC-PPPOT-T to 5000 psi. 7. V PT MV, SV,WV 8. D Bleed gas lift and production flowlines down to zero and blind flange. 9. 0 Remove wellhouse, level pad. Rig Work: (scheduled to begin on Sept 10, 2010) 1. MIRU and test BOPE to 250 psi low and 3500 psi high. 2. Swap the well to Geo-Vis. Mill 2.8" window at 12,250' and 10' of rathole. 3. Drill Build: 3.0" OH, 570' (25°/100). / 4. Drill Lateral: 3.0" OH, 1820' (12°/100). 5. Run 2-3/8" solid/slotted Bonzai completion leaving TOL at 11,980' MD. 6. Pump primary cement leaving TOC at TOL(11,980') 4 bbls of 15.8 ppg liner cmt planned. 7. Test liner lap to 2,000 psi. / 8. Cleanout run. 9. Run MCNL/GR/CCL log. 10. Set LTP. 11. Freeze protect well, set BPV and RDMO. Post-Rig Work: 1. Re-install wellhouse and FL's. 2. Run generic GLV's. 3. RU test separator, flow test well. 4. RU PBGL Mud Program: • Well kill: 8.6 ppg-brine. • Milling/drilling: 6 6 pg Geo Vis or biozan for milling, new 8.6 ppg Geo Vis for drilling. 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: 3" Casing Program: Bonzai completion • 2-3/8" L-80 solid liner- 11980' MD to 13000' MD. • 2-3/8" L-80 slotted liner- 13000' MD to 14650' MD.. • kminithum of 5.4 bbls 15.8 ppg cement will be used for liner cementing. (Assuming bottom of cement I@ f3,095i and planning on 20% excess in the open hole interval and 2 bbls over TOL to assure competent - eethent over liner lap interval) • TOC planned at 11,980' (TOL). Well Control: • BOP diagram is attached. • Pipe rams, blind rams and the CT pack off will be pressure tested to 250 psi and to.6/5,9g psi. • The annular preventer will be tested to 250 psi and 2500 psi. Directional • See attached directional plan. Maximum planned hole angle is 90°. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property—24,600'ft to the NorthWest. • Distance to nearest well within pool— 1000 ft.to L2-07A(North). Logging • MWD directional and Gamma Ray will be run over all of the open hole section. • Cased hole GR/CCL/MCNL logs will be run. Anti-Collision • L2-07A - 1,042' ctr-ctr Status: SI Producer / • L2-25 - 305' ctr-ctr Status: SI Producer Hazards • No mapped fault crossings. Well plan is parallel to an E-W trending regional fault with >500 ft. standoff. • The maximum r orded H2S level on DS 18 was 70 ppm on well 18-18B on 5/22/10. DS 18 is not considered an 12S pad and no wells on DS 18 have ever had H2S readings>100 ppm. • Lost circulation'riskris considered low for this well.

(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 log 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 shifted to a Primary Depth Control (PDC) log provided by Schlumberger GR CNL dated 28 Sep 2010 per Jennifer Flight with BP Exploration (Alaska) , Inc. (8) The sidetrack was drilled from 18-10B through a milled window in a 3 1/2 inch liner. Top of window 12250 ft.MD (8566.0 ft.TVDSS) Bottom of window 12255 ft.MD (8568.0 ft.TVDSS) (9) Tied to 18-10A at 12239 feet MD (8561.2 feet TVDSS) . (10) Baker Hughes INTEQ run 8 was utilized to open hole sidetrack at 12830 ft. MD (8649.1 ft. TVDSS) . (11) Baker Hughes INTEQ runs 3 through 7 were used to drill 18-10CPB1. (12) The interval from 14454 ft to 14486 ft MD (8636.5 ft. to 8639.4 ft. TVDSS) was not logged due to sensor to bit offset at well TD.

(5) Baker Hughes INTEQ utilized CoilTrak downhole tools and the Advantage surface system to log 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.
