Bolen MASP: 2269 psi Well Type: Producer Estimated Start date: April 1, 2015 History: R-39 was drilled in 1995 as a horizontal slotted liner completion in upper Zone 4. The well came on at a high rate, but after one year the rate had declined considerably and had a 72% WC. The problem was believed to be low vertical permeability, the horizontal section was not undulating. In 1996 we performed a 373' toe drill out, which went deeper into Z4. This initially increased the production rate considerably. The well has been on a gentle decline since. Well Integrity > 04/08/14: OART OA rides at-500 psi > 04/15/14: PPPOT-IC Passed > 05/09/14: MIT-OA Failed > 05/20/14: Set XX Plug at 9007', DGLV's sta#'s 2, 3, &4, MIT-T Failed > 05/21/14: MIT-T Passed to 2500 psi, MIT-IA Failed w/ LLR of 0.6 bpm @ 2500 psi > 06/20/14: LDL confirmed leak @ -2522 ELMD in production casing. While the well was SI in April 2014 it was noticed it would not stack out, we confirmed it was not a surface or instrumentation issue and appeared to be a down hole problem. We went on to set dummy GLV's and MIT the well. The initial MIT-T failed, we re-set 3 valves and the next MIT-T passed. The MIT- IA failed with a LLR of 0.6 bpm. We then ran an Archer LDL pumping down the IA, confirmed PC leak at 2522' MD, also saw the leak at a similar depth with echometer. Scope of Work: The primary objective of this RWO is to restore well integrity and return the well to operable status. Pre Rig Prep Work: W 1 Exercise all LDS. PPPOT-T to 5,000 psi & PPPOT-IC to 3,500 psi (if older than six months E 2 Perform a power jet cut 2-3' below the top of the collar of the first full joint above the packer. Cut depth should be -8926' MD. Refer to 6/7/95 tubing tally (4.5" 13Cr80 NSCT tubing). F 3 Circulate well with seawater and diesel FP. O 4 Cement control line with 1 gallon of squeezecrete. Displace cement with a small volume (-8 oz) of hydraulic fluid Repeat on balance line O 5 Pressure test control and balance line per the following: Perform a 5 minute test to 3000 psi. Pressure loss cannot be greater than 50 psi (10 psi per minute for 5 minutes) ✓ 6 Prep annular valves, set a TWC and dry hole tree. O 7 Remove the flow line and well house. Level the pad as needed for the rig. Proposed RWO Procedure: • MIRU Doyon 16. Pull TWC. Circulate KWF. Set TWC.. • ND tree. NU and test BOPE with four preventers configured top down (annular, 7-5/8" fixed, blind shears, mud cross and 3-1/2"x 6"VBR's). Test the fixed, blind and VBR's and annular to 3,500 psi. Pull TWC. • • Pull 4-W 12.6# 13-Cr80 tubing from jet cut—8,926' MD. • Rotate out the K anchor and remove the remaining tubing from above the packer. • Mill and retrieve the Baker SABL-3 packer. • Install lower 5-1/2" scab liner(w/RBP installed at surface). • RIH with RTTS to test lower scab. • RU E-line, Run USIT in the 75/8" casing to determine TOC in the 75/8"x 10-3/4"annulus. • Cut and pull 7-5/8" casing above TOC. • Run 5-1/2" tie-back from lower scab liner to surface. Hang in original wellhead. • Cement 5-1/2"tie-back to surface. • Pressure test 5-1/2" tie-back. • Drill out and clean out shoe tract. • Retrieve 5-1/2" RBP from lower scab liner. • Run 3-1/2" 9.3# 13Cr80 VamTop gas lifted completion. • Circulation completion fluid. Drop ball-n-rod. • Set 3-1/2" x 5-1/2" HES TNT packer. • MIT Tubing, MIT-IA. FP Well. • Set&test TWC. ND BOPE, NU dry hole tree. RDMO. Post rig Work W 1 Install new production tree. ✓ 2 Pull TWC S 3 Pull ball and rod, Pull RHC seat, Install generic GLD. O 4 Install flow line and well house. Pop Well.

Subject: FW: PBU R-39A(PTD 196-084, Sundry 315-036)Correct message Victoria, Please help me understand the concern around the 5-1/2" long string cement job. We do not routinely log scab liners or long strings when repairing production casing leaks in producing wells. While cementing the 5-1/2" long string: the reservoir will be isolated, all cementing will be performed in cased hole,the production casing leak is small (0.6BPM @2,500psi),the long string will be centralized, cement returns will be taken at surface and 20bbls excess will be pumped. I will give you a call to discuss. Ryan Daniel can address the standard well integrity monitoring plan for gas lifted producing wells. I have a general awareness of our Well Integrity Operating Practice, Ryan is the authority. Regards, Dave From: Bolen,J.e.b.

Thanx, Victoria Mr. Tom Maunder '~ ~ fU ~ ~~ ~ ~~ ~ ~ ~ Alaska Oil and Gas Conservation Commission 333 West 7th Avenue Anchorage, Alaska 99501 Subject: Corrosion Inhibitor Treatments of GPB R-Pad Dear Mr. Maunder, Enclosed please find multiple copies of a spreadsheet with a list of wells from GPB R- Pad that were treated with corrosion inhibitor in the surface casing by conductor annulus. 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.

I also reminded Mr. Whitlow of the 24 hour notification clause in the AOGCC regulations. The test went quite well with no failures observed. The area around the CTU was well laid out with good access to the unit from all directions. Summary: I witnessed the BOPE Test on CAMCO CTU 958, 0 failures, 4 hour test time.

Sec 06. TllN, R13E, UM Dear Mr Stagg: Enclosed is the approved application for permit to drill the above referenced well. The permit to drill does not exempt you from obtaining additional permits required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permitting determinations are made. Blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25.035. Sufficient notice (approximately 24 hours) of the BOPE test performed before drilling below the surface casing shoe must be given so that a representative of the Commission may witness the test. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607. David 'q~.

The horizontal production interval of this well is being extended through Zone 4 to improve vertical sweep. Drill Directional Hole: Planned for May 1 - May 7, 1996. - Directional drilling coil tubing equipment will be rigged up and utilized to drill the directional h°le as per attached plan to planned TD of 10,729' MD (8840' TVDss). Mud Program_' - FIo-Pro (8.8--8.9 ppg) Casing Program - 2 7/8", 6.16#, L-80, FL-4S Slotted liner will be run from TD to approx. 10,350' MD. Well Control: - See attachments. - Drilling operations will utilize the fully lubricated system shown in the attached diagram. The production liner will be run using the 4-ram and annular preventer system shown in the attached diag ram. - Pipe rams, blind rams and the CT pack-off will be pressure tested to 400 psi and to 4000 psi. - The annular preventer will be tested to 400 psi and 2000 psi. Directional - See attachements. Existing shoe to be drilled out: 10,375' MD (8757' TVD ss) - TD: 10,729' MD (8840' TVD ss) Magnetic and inclination surveys will be taken every 25 ft. No gyro will be run. Logging - A Gamma Ray log will be run over all of the open hole section while drilling. - A Gamma Ray/Induction/Sonic log will be run on CTE prior to running the liner. ....
