Well 2L-304 was drilled and completed in April of 2010 by Doyon 16 as a Tarn gas lifted producer. Due to parrafin and ice blockage issues the well has minimal to no uptime. This well has been selected as a heat trace candidate in support of future Willow field development and the intent is to install the heat trace down the outside of the tubing to 6500' RKB during this RWO. If you have any questions or require any further information, please contact me at +1-907-252-3347. The tubing will be pulled from a pre-rig cut. The new completion would be a stack packer and new 3 1/2" tubing with the heat trace down to 6500' RKB.

Each of these wells was found to have a void in the conductor. These voids were filled with cement and corrosion inhibitor, engineered to prevent water from entering the annular space. As per previous agreement with the AOGCC,this letter and spreadsheets serves as notification that the treatments took place and meets the requirements of form 10-404, Report of Sundry Operations. The cement was pumped in the spring of 2012. The corrosion inhibitor/sealant was pumped in the months of April and May 2012. The attached spreadsheet presents the well name,top of cement depth prior to filling, and volumes used on each conductor. Please call MJ Loveland or Martin Walters at 907-659-7043, if you have any questions. Sincerely, fi7c4á Martin Walters ConocoPhillips Well Integrity Projects Supervisor • ConocoPhillips Alaska Inc. .

The rams that were changed out for the 7-5/8" casing run were the upper pipe rams and those were tested after being changed out. After the 7-5/8" casing run we broke the wellhead to set the casing slips and did not change out any rams which explains the shell test. The 3-1/2" x 6" variables were still in the stack for the tubing run. 3 PL.- /Cr 0.-711.4 Mike Greener y 16. — 7 " u re,.4,4- ,ea....� From: Schwartz, Guy L(DOA) [mailto:guy.schwartz @alaska.gov] Sent: Monday, October 25, 2010 4:45 PM To: Greener, Mike R. Subject: 2L-304 ( PTD 210-011) BOP test question Mike, In reviewing the 407 I saw that after the 7 5/8" casing was run and cemented there is no mention of changing out the 7 5/8" BOP rams back to VBR's to run the 3.5" production tubing. Is that what happened or did the crew just fail to put it in the daily log?? All that is mentioned is doing a body test.

Z', Ze,10 ;43 4 V r r Sharon Allsup-Drake 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 1a: 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 elevations 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 TVD for the top and base of permafrost in Box 28. Item 22: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. Item 23: 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 26: Method of Operation: Flowing,Gas Lift, Rod Pump,Hydraulic Pump,Submersible,Water Injection,Gas Injection,Shut-in,or Other (explain). Item 27: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 29: Provide a list of intervals tested and the corresponding formation,and a brief summary of this box.Submit detailed test and analytical laboratory information required by 20 AAC 25.071.

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.

Gas Hydrates Moderate If observed-control drill,reduce pump rates,reduce drilling fluid temperatures,Additions of Lecithin. Gravel/Sand Sloughing Moderate Increase mud weight/viscosity,High viscosity sweeps. Monitor fill on connections Hole Swabbing/Tight Hole on Moderate • Circulate hole clean prior to trip. Proper hole fill(use of Trips trip sheets),Pumping out of hole as needed. Lost Circulation Low Prevent by keeping hole clean. If losses occur-reduce pump rates and mud rheology,use LCM 9-7/8" Hole/7-5/8" Casing Interval Event Risk Level Mitigation Strategy Shale stability in HRZ and K-1 Moderate Control with higher MW and proper drilling practices. High ECD and swabbing with Moderate Condition mud prior to trips. Monitor ECD's with PWD higher MW's required tool while drilling across pay interval. Pump and rotate out on trips as a last resort. Abnormal Reservoir Pressure Low Follow mud weight schedule and do not fall behind. Stripping Drills,Shut-in Drills,PWD Tools,Increased mud weight as needed. Ensure adequate kick tolerance prior to drilling pay interval. Lost Circulation Low Use PWD to monitor hole cleaning. Reduced pump rates,Mud rheology,LCM.
