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 AOGCC 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 AOGCC 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 an AOGCC order, or the terms and conditions of this permit may result in the revocation or suspension of the permit.

(TOC at 10,556' MD) • The primary barrier for this operation: minimum EMW of 8.4 ppg (provides 478 psi overbalance) • A cross over shall be made up to a safety joint including a TIW valve for all tubulars ran in hole. Well Control: • BOP diagram is attached. • Pipe rams, blind rams, and the CT packoff will be pressure tested to 250 psi low and 3500 psi high. • The annular preventer will be tested to 250 psi low and 3500 psi high. Directional: • See attached directional plan. Maximum planned hole angle is 91.25°. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property line: 33,500' (North) • Distance to nearest well within pool: 875' (11-32) Logging: • MWD directional, gamma ray, and resistivity will be run over all of the open hole section. • RPM log in cased hole for primary depth control Anti-Collision Failures: • None. All offset wells pass BP Anti-collision Scan Criteria. Hazards: • Drill Site 11 is considered an H2S pad • Most recent H2S level on DS-11 was at 11-09A with 140 ppm recorded on 1/15/2015 • Lost circulation potential in 11-10A is considered to be medium with one fault crossing. Reservoir Pressure: • The reservoir pressure on 11-10B is expected to be 3306 psi at 8663' TVDss. (7.34 ppg EMW) • Maximum expected surface pressure with a full column of gas (0.10 psi/ft) to surface is 2440 psi. • An EMW of 8.4 ppg will provide a 478 psi overbalance to the reservoir.

Perforations were fired from 11522' MD to 11570' MD. d.L3-31 was worked over in June 2009 to replace the 2-7/8" completion tubing. The well was also re- perforated in three intervals from 11256' MD to 11570' MD e.L3-31 was again worked over in October 2013 with a casing patch installed in the 9-5/8" at 2259' MD.The 2-7/8" completion tubing was also replaced with 3-1/2"tubing. 4) 11-32—Producer drilled in October 1994,shut-in since October 2014 due to high water cut. a.The 10-3/4" surface casing was ran to 3970' MD and cemented in place with 448 bbls(1310 sacks) and 77 bbls(375 sacks)tail. b.The 7-5/8" intermediate casing was ran to 11003' MD and cemented in place with 147 bbls 11 ppg lead and 80 bbl 15.7 ppg tail. Estimated TOC is at 10783' MD. Perforations were fired on multiple occasions from 10658' MD to 10844' MD. c.The 11-32 was completed with 4-1/2"completion tubing. 5) 11-32A—Not drilled yet,scheduled as a December 2015 CTD sidetrack(PTD 194-131) ,/`) 3.4-- .. { 4,t ,-)41,-, .`. �A .,,,,,,, 0 NI x t :µms. ; ., Sr.. k ,t .cam ; 0 CO r4 y., •• ter,.-' ,r' f dry /X, ` ' ;LI ',/ / 4 C M ,,. t .-•/' i. 00 .. ,,,j r ""'-..,,y r, ;yam].. ..„ ,..„ ,..,..„,, ,, / .."_, ttf 14v1' 'fi w J. - ••.41 " 'It '' .4 ''''' ,,,',-, moC E .0, ,... -\ : .del t,. x. �Mr/ e # as (1) ...) tin IMIMPINNION . l ] •!s 13 0,,, E -,..3 , (1) J _.
