This permit supersedes and replaces the permit previously issued for this well dated March 19, 2010. 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.

The parent, B -08, is a mature cycle well in the GDWFI with a 12 month on -time of 6 %. This sidetrack will move the wellbore 1400 feet to the southwest toward the edge of the waterfront for better support and to reposition away from the current gas cone. A coiled tubing sidetrack was planned this year, but a surface casing leak developed in the parent well before it could be drilled. This a rotary sidetrack permit request replaces the earlier permitted CTD well and includes casing repair as part of the sundry work. The uppermost production packer in the parent well is positioned below the top Sag River allowing for a reservoir kick -off on this sidetrack. 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 production liner will be 4 -1/2" 13Cr and fully cemented. Tubing will be 4 -1/2" 13Cr, tied into the top of the production liner.

Now the well will be a rotary sidetrack after repairing the leak, kicking off at 9000' MD (several hundred feet higher than coil had planned).

B -08 is a deviated Zone 2 producer well that was drilled and completed in May, 1978. A Rig Workover was done in April, 1990 to run a GSO straddle across due to high GOR. A second RWO was done in June, 1999 to change out corroded tubing leaving the GSO straddle from 1990 in place. At some point the lower packer in the straddle failed. There is no clear indication on the production trend but, an STP run in May, 2000 shows 100% fluid entry at the base of the tailpipe at 9610' and an RST /Borax log run on November, 2000 shows borax up into the 25P interval behind the straddle. B -08 continued to produce after that but, was treated as a strong cycle well with high on -time. This lasted through 2008. After that it no longer healed, was no longer competitive and was SI. Utility of well B -08 will be restored by sidetracking away from the gas cone and back into Waterflood support. The sidetrack, B -08A, is scheduled to be drilled by Nordic 1 starting on April 10, 2010. This horizontal lateral will target Ivishak Zone 2. The perforations in the parent well will be abandoned with a cement plug in the 9 5/8" casing. The "A" sidetrack lateral will exit the parent well at -9,650' MD in the Ivishak Sand 24P and drill a - 1,950' lateral to a TD of 11,620' MD. The sidetrack will be completed with a solid, cemented and perforated 2 -3/8" liner. The following describes work planned. A schematic diagram of the proposed sidetrack is attached for reference. CTD Sidetrack Summary Pre -CT Rig Work: The pre CTD work is slated to begin March 26, 2010. 1. F MIT -IA to 3000 psi, MIT -T to 3000 psi. 2. W PPOT -T to 5000 psi, PPOT -IA to 3500 psi. 3. S Pull 3'/2" PX Plug at 9395' MD. 4. S Drift for E -line 3'/2" tubing tail pipe cut and cement job. 5. S Run dummy whipstock drift. 6. E Cut 3'h" tubing tail pipe at 9595' MD (5' below the bottom of lower most 9 5/8" x 3'/2" casing packer) and let fall. 7. C Cement from PBTD to tailpipe (pump 37 bbl of 17 ppg cement) 8. C Freeze protect the well and thoroughly wash the tree. 9. W Bleed wellhead pressures down to zero. 10. 0 Bleed production flow lines and GL lines down to zero and blind flange. 11. F MIT -T to 1000 psi. 12. 0 Remove wellhouse, level pad. Rig Sidetrack Operations: (Scheduled to begin on April 10, 2010 using Nordic Rig 1) 3/0-073 1. MIRU Nordic Rig 1 2. NU 7- 1/16" CT Drilling BOPE and test 3. Mill 2.8" pilot hole to 9675' MD. 4. Run dummy whipstock drift 5. Set whipstock highside at 9,650' MD. 6. Mill 2.8" window in 9 5/8" casing from mechanical whipstock 7. Drill build section with 3" bicenter bit, and land well in target Ivishak Z2 sand. 8. Drill lateral section to 11,620' MD. 9. Flow check well and lay in KWF as needed. ✓ 10. Run and cement a 2 -3/8" L -80 liner string. Expect -8.8 bbl of 15.8 ppg cement. 5 rrl) 11. Make a cleanout run with mill and motor. +Ckt- 12. Make a logging run with a memory SWS GR -CCL logging tool. 13. Test Liner lap to 2000 psi. 14. Perforate well. 15. FP well to 2000'. 16. ND 7-1/16" stack. FP tree and PT tree cap to 3500 psi. 17. RDMO Nordic 1. Post -Rig Work: 1.' Re- install wellhouse and FL's • 2. Pull BPV. 3. RU test separator. Mud Program: • Well kill: 8.6 ppg seawater / brine. • • Milling /drilling: 8.6 ppg Geo -VIS or biozan for milling, new 8.6 ppg Geo -VIS for drilling. Disposal: • All Class II drilling and completion fluids and all other Class II wastes will go to Grind & Inject at DS 4. ' • All Class I wastes will go to Pad 3 for disposal. Hole sizes: 3.0" bi- center hole: 9,350' MD — 11,620' MD Casing Program: • 2 -3/8 ", 13Cr -80 4.70# STL 9,390' MD — 11,620' MD • • A minimum of 8.8 bbl 15.8 ppg cement will be used for liner cementing. (Assuming 3.0" bit size and TD C 11,620', with 20% excess in the open hole interval) • TOC planned at 9,350' MD (top of 2 3/8" liner). • A liner top packer will be run, if liner lap fails. 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. Maximum planned hole angle is 106 deg at 9,864' MD. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property — 2150 ft (to planned perforations in new lateral). • Distance to nearest well within pool — 855 ft (from B -08A to B -03B). Anti - Collision • There are no collision issues Logging • MWD directional, Gamma Ray and Resistivity logs will be run over all of the open hole section. • A cased hole GR /CCL/CNL log will be run. Hazards • The maximum recorded H level on B pad was 400 ppm on well B -34 (June 1995). • The maximum recorded H level on B -08 was 20 ppm (March 2008). • The lost circulation risk for B -08A is considered moderate -low due to the possible fault crossing and history of lost circulation in the area. One possible fault (Fault #1) will be encountered several hundred feet after kick -off which cannot be avoided. The parent well possibly encountered Fault #1, but suffered no losses. Reservoir Pressure • The reservoir pressure is estimated to be 3,304 psi at 8,949 TVDss (7.1 ppg equivalent). • Max. expected surface pressure with gas (0.10 psi /ft) to surface is 2,409 psi. • Eli Vazquez CTD Engineer CC: Well File Sondra Stewman/Terrie Hubble TREE = MCEVOY SAFETY OTES: 190 WELLHEAD'= MCEVOY -O M EAST ENTS 1990 v 0 BELOW BKR PKR (TBG ACTUATOR = AXELSON KB.
