Change is approved as described below. I will make a note in the well file. Guy Schwartz Senior Petroleum Engineer AOGCC 793-1226 (office) 444-3433 (cell) From: Ross, Matthew [mailto:rossmo@BP.com] Sent: Friday, January 11, 2013 9:00 AM To: Schwartz, Guy L (DOA) Subject: 01-17C Change to top of liner&top of cement Guy; Originally we had planned to keep the top of the 2-3/8" liner&top of cement low at 8837'md. We cannot configure the space out of the liner&liner top packer properly as first proposed. Due to lengths of the new 2-3/8" liner equipment(deployment sleeve, scoop guide¢ralizer with new liner top packer)&shortage of 4-1/2"tubing space(only 1 joint),we would like to move the top of liner&top of cement to inside the 4-1/2" chrome tubing at 8650'md.This will increase out cement pumped from 13bbls of class `G' cement to 15bbls of class`G' cement. I have attached the new well bore schematic for your reference. Please let me know if you agree with the new changes.

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.

Directional: • See attached directional plan. Maximum planned hole angle is 141.78°, inclination at kick off point is 44.55°. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property— 22,250'. • Distance to nearest well within pool — 550' from 01-02. Logging: • MWD directional, Gamma Ray and Resistivity will be run over all of the open hole section. • Open hole caliper log will be run should hole conditions warrant from 9,200' MD to 11,253.6' MD. • Cased hole GR/CCL/MCNL logs will be run. Perforating: • SWS 1-1/16", 6 spf, perf guns, 1" CSH work string, & 2-1/16" PH6 • The primary barrier for this operation: a minimum EMW of 8.4 ppg. • A X-over shall be made up to a safety joint including a TIW valve for all tubulars ran in hole. Anti-Collision Failures: • None , Hazards: • DS 1 is not considered a H2S pad. Well 01-34A had 60 ppm H2S on 3/06/2011. • Most recent H2S level on 01-17B is 16 ppm recorded on 1/13/2012. • The lost circulation risk in 01-17C is considered to be low with no fault crossings planned. Reservoir Pressure: • The reservoir pressure on 01-17C is expected to be 3,217 psi at 8,800' TVDSS. (7.1 ppg equivalent). • Maximum expected surface pressure with gas (0.10 psi/ft) to surface is 2,337 psi. . • An EMW of 8.4 ppg for this well will provide 626 psi over-balance to the reservoir.
