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, Daniel T.

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: 3.00" (bi-center bits used) Casing Program: fully cemented liner • 2-3/8", 13-Cr80 4.70# STL 9,530'md -14,160' and • A minimum of 22.2 bbls 15.8 ppg cement will be used for liner cementing. • TOC planned at 9,530' Existing casing/tubing Information 10-3/4", J-55 45.5#, Burst 3,580, collapse 2,090 psi 7-5/8", L-80, 29.7# Burst 6890, collapse 4790 5-1/2", 13-Cr80 17#, Burst 7740, collapse 6290 psi 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 99.5 deg at 10,250'. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property line -15,690 ft. • Distance to nearest well within pool - 1,421ft. (04-27 ~ 13,550') Logging • MW D directional, Resistivity and Gamma Ray will be run over all of the open hole section. • Cased hole MCNVGR/CCL will be run. Hazards • The maximum recorded H2S level on Drill Site 04 was 1400 ppm on well 04-41. • Two planned fault crossings, calculated risk of lost circulation is medium. Reservoir Pressure • The reservoir pressure on 04-35 is expected to be 3,391 psi at 8,800' TVDSS. (7.41 ppg equivalent) • Max. expected surface pressure with gas (0.10 psi/ft) to surface is 2,511 psi. C.R.Reynolds CTD Engineer CC: Well File Sondra Stewman/Terrie Hubble TREE _ ?

Page 1 i ~~-oar( ~~q(o5 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) log from well 04-35A dated 03 May 2009 above the Kick off Point of 11783 feet MD per Daniel Schafer with BP Exploration (Alaska), Inc. (8) The sidetrack was drilled from 04-35 through a milled window in a 5 1/2 inch liner. Top of window 9900 ft.MD (8540.2 ft.TVDSS) Bottom of window 9906 ft.MD (8545.1 ft.TVDSS) (9) Tied to 04-35 at 9880 feet MD (8521.9 feet TvDSS). (10) The interval from 12315 feet to 12355 feet MD (8643.2 feet to 8646.9 feet TvDSS) was not logged due to sensor to bit offset at well TD.
