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, Dan T.

June 17, 2009 • B-16A - Coiled Tubing Dri ing Mud Program: • Well kill: 8.6 ppg brine • Milling/drilling: 8.6 ppg Flo Pro or biozan for milling, new Flo Pro 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: 4-1/8" Casing Program: • 3-1/2", 8.81 #, L-80, STL connection solid liner - 8,840'MD - 9,650' MD. • 2-7/8", 6.4#, L-80, STL connection solid liner - 9,650'MD - 11,675' MD. • A minimum of 25 bbls 15.8 ppg cement will be used for liner cementing. (TOC 9,400'MD) Well Control: • BOP diagrams are 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 97° deg. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest well within the pool (Ivishak) - 790' B-23 • Distance to nearest property line - 23,025' Anticollision Summary • B-23A - 795' ctr-ctr, Status: Producing • B-02A 1073' ctr-ctr, Status: Shut in • B-22 - 1076' ctr-ctr.

A BOT service hand will be on the unit for the window milling. • Use a 2# Bio or GeoVIS sweeps to help clean the metal shavings out of the well. • Slow patient milling will be the key to a successful window. There is nothing to be gained trying to speed up the window. • Ensure the window is dressed and smooth. Operations 1. RIRU, Test BOPE per SOP. 2. Fill upright tank with 2% KCL milling fluid. 3. Make up the following BHA to mill through the liner: o Hughes Christensen 3.80" diamond window mill (P/N E0378) o Hughes Christensen diamond reamer 3.80"go/3.79"nogo 0 2'/8" Baker X-treme straight motor 0 2-3/8 PH6 pup joint (no weight bars) o Circ sub, Disconnect, DFCV o CTC back to 1.75" CT o Record gage go/nogo on both mill & reamer. o The mills will be made up to the motor at the BOT shop. 2. RIH displacing the well to 2% KCl milling fluid, shut down pump, & lightly tag (1000# WOB) the pinch point dry (planned TOWS @ 9694'). The pinch point on this 4-1/2" x 7" WS is 4.6' from the TOWS. 3. PU 10+', bring pump to full rate (~2.5 bpm), & RIH slowly. Note RIH weight & free spin pressure. Be prepared to tag 1'-2' above dry tag when pumping at full rate. 4. Tag TOWS as indicated by a 250-300 psi increase in pump pressure & flag pipe. If motor stalls, PU & time drill down at 1'/hr. Monitor motor work & limit to a 300 psi increase for the 1St one foot below the TOWS. Monitor & record WOB. 5. Slowly increase motor work after milling 1' using 400 psi as a maximum. Expect ROP less than 1'/hr until mill cuts through the liner wall. Afterwards expect 2-3k# WOB & 1'-3'/hr ROP. o Pump sweeps to ensure the metal is being removed from the hole. In the past there has been an issue with solids settling in the sump and the drilling assembly was not able to pass thru the window. 6. The mill-off could be as much as 8.9' down from TOWS. But, will likely occur ~7' down from the TOWS based on past windows. If mill off does not occur before the theoretical Bottom of the window, control mill at 1'/hr until the mill has reached 9' below TOWS. Mill-off will be indicated by an abrupt decrease in WOB & increased ROP. Record this depth as the bottom of the window. 5~ f ~ `fie. ~~ ` ~ ~ ~~`~ ,, ~1 June 17, 2009 . • B-16A - Coiled Tubing Drilling 7. Drill a minimum of 10' in the formation. Sand in the returns is usually a good indication the window exit is successful. If there is any doubt catch a fluid sample and take it to the geologist on either Nordic 1 or 2. Ream up & down from the WS face to 2' below the window bottom several times at 1'/min. 8. Pump a 150k LSRV GeoVIS pill to leave on bottom to prevent any remaining cuttings from falling into the rathole. 9. POOH leaving a 2000' freeze protect cap.

Page 1 ~pG'1 - (NCO ~ ! $ ~~~ • • tapescan.txt (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 adjusted to a Primary Depth control <PDC) to provided by schlumberger GR CNL dated 03 Aug 2009 per Cole Abel with BP Exploration (Alaska), Inc. (8) The sidetrack was drilled from B-16 througg.h a milled window in a 7 inch liner. Top of window 9694 ft.MD (8494.1 Tt.TVDSS) Bottom of window 9703 ft.MD (8501.1 ft.TVDSS) (9) Tied to B-16 at 9600 feet MD (8419.2 feet TVDSS). <10) The resistivity interval from 9690 feet to 9740 feet MD (8490.6 ft to 8526.6 ft TVDSS) was logged 6.5 hours after drilling run 2. (11) Baker Hughes INTEQ runs 3 through 8 were used to drill B-16AP61. (12) The B-16A was completed with and open Hole. sidetrack at 9740 ft. (8526.6 ft. TVDSS). (13) The resistivity interval from 9740 ft. to 10340 ft. MD (8526.6 ft to 8804.1 ft TvDSS) was logged 12 hours after drilling on runs 10 and 11. Data has been correlated to drilled Gamma Ray data and depth shifted +4 ft. (14) The interval from 11550 ft to 11590 ft MD (8913.7 ft to 8936.0 ft TvDSS) was not logged due to sensor to bit offset at well TD.
