Joe Lastufka, 564 4091 Well Number Permit No./Approval No. Drilling Engineer: Chidibere Igbokwe 564-4795 INSTRUCTIONS General: This form is designed for submitting a complete and correct well completion report and log on all types of lands and leases in Alaska. 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.

Sidetrack operations in PBU 09-44A were temporarily shut down after drilling to 13860' MD when the bottom hole assembly containing a nuclear source became stuck. The drill pipe was severed at 12520' MD and the BHL including the source was isolated with the top of cement calculated at 12470' MD (Sundry 310-075). In addition to the open hole cement plug isolating the nuclear source, the well is secured with a cement retainer set in the casing at 12140' MD with 21 barrels of 15.8 ppg cement pumped below and 5 barrels of cement left above the retainer. The top of cement is calculated to be at 12010' MD. Prior to pumping cement, the casing and retainer were tested to 2500 psi. The Operations Shutdown was approved on 3/24/10 (Sundry 310-083) and extended on 4/01/11 until 3/30/12 (Sundry 311-102). Current East of Sag River drilling plans indicate the well will not be re-entered for at least several years. BP Exploration (Alaska) Inc. proposes to change the status of PBU 09-44A from �'- Operations Shutdown to a Suspended Well.

The corrosion inhibitor is engineered to prevent water from entering the annular space and causing external corrosion that could result in a surface casing leak to atmosphere. The attached spreadsheet represents the well name, API and PTD numbers, top of cement depth prior to filling and volumes of corrosion inhibitor used in each conductor. As per previous agreement with the AOGCC, this letter and spreadsheet serve as notification that the treatments took place and meet the requirements of form 10-404, Report of Sundry Operations.

Additionally, you should apply for an Operational Shutdown (instead of a well suspend)with the 403 since the well was never completed. You have 1 yr to re-enter the well and finish drilling that way before having to suspend the well. The P &A portion of the wellwork can be submitted on a separate 407 as usual but the drilling portion should be captured with a 10-404.

Volume of 25 bbl's 15.8 class G cement was pumped thru cement retainer & volume of 5 bbl's 15.8 class G cement was placed on top of retainer effectively covering 130' of 7" 26# casing above retainer. I witnessed cement retainer setting tool be POOH to a measured depth of 11,600' very slowly to minimize disturbance of cement on top of retainer. Circulation of a bottoms up was witnessed @ Rig shale shakers verifying no cement circulated to surface. Cement retainer casing test was performed to verify casing & retainer integrity. Pressure of 2553 psi was applied to cement retainer & 9 5/8" casing to a depth of 8232" MD with 7" liner to plug back depth of 12.010' MD.

Additionally, you should apply for an Operational Shutdown (instead of a well suspend)with the 403 since the well was never completed. You have 1 yr to re-enter the well and finish drilling that way before having to suspend the well. The P &A portion of the wellwork can be submitted on a separate 407 as usual but the drilling portion should be captured with a 10-404.

A 6 -Y8" horizontal production hole will then be drilled in zones 1 and 2 to a final well TD at -18,888' MD where a 4 -W, 12.6 #, 13 -Cr liner will be run to TD and cemented. The planned completion for this well will include a 4 -W, 12.6 #, 13 chrome tubing string with gas lift mandrels and a permanent production packer. This well is currently scheduled for Nabors 7ES beginning -01/15/10.

Based upon calculations below, BOP equipment will be tested to 3,500 psi.

Planned completion fluids 8.5 ppg Seawater / 6.8 ppg Diesel Other Request: Given rig floor height limitations, a MASP < 3000 psi, and the fact that the three ram drilling BOP configuration is preferred to a two ram configuration with a spool, BPXA will execute the provisions of 20 AAC 25.285 (f) (1) regarding the initial testing of the BOPE as follows when existing wellhead or testing equipment prevents the testing of the lowest set of pipe rams: That • lowest set of rams will be tested at the earliest opportunity during path - forward de- completion work, i.e., after the completion has been pulled from the well. Safety concerns and spacing limitations with the wellhead height and tubing spool preclude us from installing a spacer spool in the three -ram drilling BOP stack. Disposal: • No annular injection in this well. • Cuttings Handling: Cuttings generated from drilling operations will be hauled to grind and inject at DS -04. Any metal cuttings will be sent to the North Slope Borough. • Fluid Handling: Haul all drilling and completion fluids and other Class II wastes to DS- 04 for injection. Haul Class I waste to DS -04 and /or Pad 3 for disposal / Contact the GPB Environmental Advisors (659 -5893) f /guidance.

The main objective of the 09 -44A sidetrack is beyond the heel of the section to the east - southeast. Landing close to 09 -24 does provide good correlation for depth control, however. In our risk analysis of the close approach we have recognized the potential for intersection (albeit unlikely due to the high survey error in 09 -24) and deemed the consequences to be minimal since 9 -24 is plugged above the TVD at which 09 -44A will pass it. Nevertheless we will shut in 9 -24 while drilling inside the error ellipse to minimize the most consequential outcome of an intersection should it occur, that is the sudden lost circulation while drilling. The proposed 9 -44A well plan passes 09 -21 significantly farther away and just slightly into the 1200' error ellipse that defines major risk. Like 9 -24, the consequences of an intersection are minimal and 09 -21 will be shut in as a precaution. Feel free to follow up with me if there's anything else I can provide. Phil Smith Senior Drilling Engineer From: Schwartz, Guy L (DOA) [ mailto:guy.schwartz @alaska.gov] Sent: Friday, December 04, 2009 9:06 AM To: Smith, Phil G (ASRC) Subject: 09 -44A question (PTD 209 -157) Phil, I am reviewing the PTD for 09 -44A. The close crossings involving 09 -24 and 09 -21 are interesting .. can you supply a spider map of the wellbore trajectories. Apparently 09 -24 is isolated with an IBP (but these are somewhat unreliable.) Why so close in the plan? Are both wells SI at surface during the drilling ?? ... would like more info on these two wells and the thought process.
