In 2010, a subsequent deep tubing leak developed but patching was not successful. Additional diagnostics were performed and it was determined that the PBR patch was leaking. This patch was pulled and the well was left not operable. In 2014, a `559' snap latch patch was installed that did not hold pressure. This patch is not recoverable in the original segment lengths and will be left in hole. Both sections of TxIA will be repaired With a cement IA squeeze. By repairing this well with an IA cement squeeze, it is estimated that an incremental 83 mbo can be produced over the next several years. Without the IA cement squeeze, this well has no remaining value. Scope of Work: Repair TxIA with IA cement job. Return well to injection. ✓ Job Notes: • CMIT-TxIA passed to 2500psi on 6/28/15 with a X test plug at 13287'md in the patch. o Lower packer is holding, QCLL connections are leaking in numerous places • Reservoir Pressure: 3,772 psi at 8800' TVDss • Reservoir Temp: 141F • Cretaceous Stratigraphy: o Top of UG4 5010' TVDss / 6708' MD, o Top of CM3 6985' TVDss / 10391' MD • The OA has a closed shoe.

Well was injecting until 2008 when a tubing hanger leak was detected. Subsequent caliper log indicated a hole at 13,240' MD. LDL also found a leak at PBR at 13,249' MD. A patch was set in joint above PBR in October 2008. High IAP was reported in Jul 2010. LDL found leak MD and TxIA communication was 9 p July @ 12 510 confirmed. A caliper log run in August 2010 showed multiple holes at 13,339' MD. Packer squeeze was considered however, the economics did not support that as an remedy option. Detailed well integrity history is attached as a reference. An extended patch is recommended to isolate holes in the tubing. The procedure calls for the 4.5" QCLL system (Quick Connect Liner Latch by Northern Solutions) to deploy a 3 -1/2" tubing patch with slick line in place. Objectives The goal of this procedure is to run and set an extended tubing patch using the QCLL system. After the liner has been set in place and pressure tested the well will be put back on injection for r reservoir management. cc: w /a: Well File Contacts: Matt Brown Chidi Igbokwe Carl Diller Bob Harris 564 -5874 (w) 564 -4795 (w) 307 - 258 -6679 907 - 240 -0427 223 -7072 (c) 206 - 790 -2449 Attachments Wellbore Schematic Lau pumping form QCLL Liner tally QCLL diagrams Integrity history 2 • • Job Notes • The QCLL components are being manufactured by Unique Machine & will be sent to the Slope. p 9 Y q p Carl Diller /Bob Harris will be on site to run the QCLL system on SL as well as for the CT e. procedure to deploy the QCLL liner & cement it in place.

Continue with Slickline- Deploy QCLL procedure below. Slickline = De do QCLL ,% % ' '''% 1. Set releasable X -lock on S/L at 13,365'. The lock is configured with a 4" GS "receptacle" in place of the standard 4" GS fish neck adding additional length to the lock. It is run on a standard X -Line running tool with an extended core specifically for this lock. The lock is delivered so once set, 1600 #'s over pull at the tool is required to release. Once released, the lock is pinned to remain in the full open position up to 3200 #'s set down weight. It is run with no packing and has a 3.700" Maximum OD to allow passage through the 3.725" "XN ". 2. Ensure all QCLL components have been drifted and are laid out in the proper running order. QCLL to be drifted with 2.75" OD drift at machine shop after make up. 3. MU QCLL running tool to shoe joint. Shoe joint will consist of QCLL mandrel, Stage Collar or shear out ball seat (set at -1000 PSI), float collar, float collar, joint ( +/- 15' TBD), Back Door Flapper Valve (BDFV), joint ( +/- 15' - TBD), QCLL mandrel, and QCLL running tool. 4. RIH at moderate rate slowing down at all GLM's and jewelry. Get good up and down weights about 200' above lock. RIH at +/- 50 FPM and engage lock at 10426'. PU < 200 #'s (DO NOT PULL MORE THAN 200 #'s) over previous weight check to ensure QCLL Body Lock Ring (BLR) is engaged. Spang down +/- 5 -10 times on lock to fully latch QCLL. PU slowly to open spang and establish free movement from shoe joint. If over pull is noted, repeat down spanging. 5. POOH 6. MU and run remaining QCLL liner joints. These joints differ slightly from the shoe joint as they have the Receptacle box down and the mandrel up. Run as per step 4. 7. Run Baker deployment sleeve with 4 "/4'/2" GS with pup joint and final QCLL receptacle. 8. RDMO 3 • TREE= MC GEN 4 WELLHEAD= FIC CTUS TOW Axa.S43t4 04-28 SAFETY POIES: KB MEV = 65' BF.

Yau have noted the patch on the 404, thanks. The question I have concerns the description of the patches. DS 09-06 (176-048) -- In this well, 5-112" tubing was patched however the patch is also listed as 5-112". I don't think this is correct since the patch dimensions are smaller than the actual tubing patched. fn the operations summary, the ID of the patch is given as 2.992" which would lead me to believe that the actual patch is 3-1/2" tubing. DS 04-28 (185-280) - In this well, 4-1/2" tubing was patched however the patch is also Listed as 4-1/2". Again, t -~` don't think this is correct since the patch dimensions are smaller than the actual tubing patched. 1 did not find an ID given in the operations summary, but t would hazard a guess that the actual patch is 2-7/8" tubing. Also, was this the well that you had contacted me regarding not getting a sundry since this is an injection well? Would you look into this and get back to me. 11/21/2008 04-28 (185-280) Maunder, Thomas E (DOA) Page 1 of 1 From: Maunder, Thomas E (DOA) Sent: Tuesday, November 04, 2008 1:55 PM To: 'Preble, Gary B (SAIC)' Cc: Chiwis, Robert; Regg, James B (DOA) Subject: RE: 04-28 (185-280) Gary, Just send in the 404.

The well has been reclassified as Operable and may be put on injection when convenient for Operations. Please be careful of annular fluid expansion on the IA as it is liquid packed. An AOGCC MITIA will be conducted once the well is online and stable. The plan forward for the well is as follows: 1. Wireline: Run patch -DONE 2. Fullbore: MITIA to 2500 psi -PASSED 3.

Mr. D. F. S cheve ARCO Alaska, Inc. P. O. Box 100360 Anchorage, AK 99510-0360 Dear Mr. Scheve: You have requested waivers to rule lla of C.O. 165 for PBU wells 4-22 and 4-28 by Application for Sundry Approvals dated Novem- ber 5, 1986. These wells are producing from less than 30 feet of perforations. In each case the perforations are contained in a single zone. Therefore a productivity profile is not necessary to determine well flow from different zones. The Commission hereby approves your request to waive the pro- duction profile required by rule lla of C.O. 165 in PBU wells 4-22 and 4-28.

Well 4-28 is presently on a rotating production schedule of producing for 12 days followed by a shut in period of 20 days. The static bottomhole pressure is planned to be taken at the end of the shut-in period. The static bottomhole pressure survey should provide an accurate measurement of reservoir pressure. 2. Permission to waive the production profile prescribed in Conservation Order 165, Rule 11a. Only 29' of perforations were shot in 4-28. All of the perforations were shot in Zone lB thereby negating the need for a spinner survey. Perforations in Zone 2 are planned. The timing of the perforations, however, is after the initial six month time period has passed. A production profile will be run subsequent to the additional Zone 2 perforations.

Describe proposed program: ARCO Alaska, Inc., proposes ~o directiona11¥ drill this Sadlerochit injection well to 13,726'HD (8921'TVD). A 20"~ 2000 psi annular d~ver~er will be installed and operationally tested prior to spud. The 13-5/8"~ 5000 ps~ RSRRA BOPE s~ack mill be ~nstalled and tested (rams 5000 ps~, annular 3000 psi) weekly upon installation and operationally tested each trip. After reaching TD, logs will be run across selected intervals. The well will be completed as an injector using a workover rig at a later date. A 4-1/2" tubing string and packer will be run and set above the Sadleroch~t. A downhole safety valve w~11 be ~nstalled and tested upon completion of the job. Selected intervals will be perforated in the Sadlerochit formation and reported on subsequent reports. Reserve pit fluids will be disposed of down the 7-5/8H x 10-3/4" annulus of this well. The 7-5/8" x 10-3/~" annulus w~11 be left with a non-freezing fluid during any Jnterruption in the disposal process. Upon completion of the disposal process, the annulus w~ll be sealed w~th 200 sx of cement followed by Arctic Pack. * The following additional wells are within 200~: DS 4-13, 172' ~ 1650'HD[ DS 4-15~ 61' ~ surface~ DS ~-29~ 119' ~. 1500'HD (as planned) and DS 4-30, 180' ~ surface.
