Confirm good log data. 6. At surface, prepare for deployment of TCP guns. 7. Flag pipe as appropriate per WSL for adperf/CBP runs. 8. Confirm well is dead. Bleed any pressure off to return tank. Kill well w/KWF, 8.4 ppg 1% KCl or 8.5 ppg as needed. Maintain continuous hole fill taking returns to tank until lubricator connection is re- established. 9.Pickup safety joint and TIW valve and space out before MU guns.Review well control steps with crew prior to breaking lubricator connection and commencing makeup of TCP gun string. Once the safety Well: J-16B PTD:212-014 joint and TIW valve have been spaced out, keep the safety joint/TIW valve readily accessible near the working platform for quick deployment if necessary. 10.

Box 196612 Anchorage, Alaska 99519 ``- p ( August 02, 2013 To Whom It May Concern, I had previously sent out an email on 07/18/2013 about the numerous J- 16BPB1 CD distributions. However, as we attempted to load the .dlis from the CD dated 07/17/2013, the .dlis data was corrupted. Hence, we have another CD. This CD contains PDFs, dlis data file, las data file, excel and text files. However, the .cgm files are missing. The PDFs should be adaquate as they are versions of the .cgms. If for some reason you do need the .cgms they are on the previous CD dated 07/17/2013. I appreciate your time and attention. If you have any questions feel free to contact me or Dave Douglas at any time! Sincerely, Analisa Steger 1►►�r Steger, Analisa (Wipro Technologies) From: Steger,Analisa (Wipro Technologies) Sent: Thursday,July 18, 2013 3:48 PM To: makana.bender@alaska.gov Subject: J-16BPB1 Baker Hughes Good Afternoon Makana, We(BP PDC-specifically Dave Douglas site lead)had requested that the third CD that was sent out from Baker Hughes be sent to us for distribution so that we explain the numerous prints and CDs.I am sincerely sorry that Baker Hughes did not comply with that wish. You should have received 3 packages from Baker Hughes with J-16BPB1 log prints and CDs. 1. The first package of prints did not have proper/clear headers and the cd did not contain necessary data. Please dispose/recycle/shred the prints and CD sent on 07/03/2013. 2. The replacement distribution was sent on 07/15/2013 this second package had the updated/correct log prints-if you received the prints-please retain.The CD,however,was again missing the PDFs and DLIS files-please discard this CD. 3. The last package you received (probably today)was sent on 07/17/2013. It was the CD by itself.The CD is dated 07/17/2013 and says"Corrected Data"on it.This CD is good-has all data files. In recap,please keep the second batch of log prints and the 3rd"Corrected Data"CD. If you have any questions,feel free to contact me or Dave Douglas(david.douglas@bp.com). Again,please accept our apologizes to the numerous distributions for J-16BPB1,however,we want to make sure you receive the best and correct data. Have a great afternoon!

Submit a well schematic diagram with each 10-407 well completion report and 10-404 well sundry report when the downhole well design is changed. Item 1 a: Classification of Service Wells: Gas Injection,Water Injection,Water-Alternating-Gas Injection,Salt Water Disposal,Water Supply for Injection, Observation,or Other. Multiple completion is defined as a well producing from more than one pool with production from each pool completely segregated. Each segregated pool is a completion. Item 4b: TPI(Top of Producing Interval). Item 8: The Kelly Bushing and Ground Level elevation in feet above mean sea level. Use same as reference for depth measurements given in other spaces on this form and in any attachments. Item 13: The API number reported to AOGCC must be 14 digits(ex: 50-029-20123-00-00). Item 20: Report true vertical thickness of permafrost in Box 20. Provide MD and ND for the top and base of permafrost in Box 28. Item 23: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. Item 24: If this well is completed for separate production from more than one interval(multiple completion),so state in item 1,and in item 23 show the producing intervals for only the interval reported in item 26. (Submit a separate form for each additional interval to be separately produced, showing the data pertinent to such interval). Item 27: Method of Operation: Flowing,Gas Lift,Rod Pump,Hydraulic Pump,Submersible,Water Injection,Gas Injection,Shut-In,or Other(explain). Item 28: Provide a listing of intervals cored and the corresponding formations,and a brief description in this box. Submit detailed description and analytical laboratory information required by 20 AAC 25.071. Item 30: Provide a listing of intervals tested and the corresponding formation,and a brief summary in this box. Submit detailed test and analytical laboratory information required by 20 AAC 25.071.

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.
