In 2006, a CTD sidetrack was drilled due to the high GOR of the C-34 wellbore. The well was shut-in in February of 2016 due to TxIA communication. Shortly after, slickline attempted to set a CIBP just above the top perforation at 9,855' MD. However, slickline made numerous attempts to get deeper than 9,380' MD and eventually set the plug at 9,372' MD. The plug is-102' TVD above the top perforation. The C-34B wellbore has no remaining well work options and therefore has been released for sidetrack. Scope of Work: Prior to rig arrival, the C-34B perfs will be abandoned via fullbore cement. Initially, 25'of cement will be dump bailed on ton of the CIBP. Secondly,the P&A plug will be placed on top of the-In-Ear 25'of cement. The plan is to not tag the dump bailed cement in order to prevent numerous rig ups for cementing and thus reducing HSE risk. Due to the request to not drift and tag the initial cement plug, it is proposed that an AOGCC representative witnesses the bail cement job. The final top of cement will be determined with a drift run followed by an integrity test of the tubing and IA.The 4-1/2"tubing will be cut and wellbore integrity will again be verified. The rig will then move over the well and pull the 4-1/2" tubing and the top —2 joints of 9-5/8" casing. A 9-5/8"whipstock will be used to mill a window out of the existing production casing at—3500' MD. This sidetrack is a horizontal producer targeting the Ivishak. The planned well is a two string, ultra-slimhole design using 7" intermediate casing and 4-1/2" production liner. The intermediate casing will be set at the top of the Sag River, and the production interval will be completed with a cemented and perforated liner.

Install VR plugs in the annulus valves as needed and secure the well. Ensure that both IA and OA are protected by two barriers. 47. RDMO. Post Rig Operations: 1. DSM Pull TWC. 2. MIRU slick line. Pull ball and rod/RHC plug from landing nipple below production packer. 3. Run RPM log and determine perf interval 4. Perforate to access Zone 2 and Zone 4 reserves 5. Install GLVs. Drift SBHPS. 6. ASRC Flow Back 7. Install the well house, instrumentation Contingency Plan: 48. A deep cut of the 9-5/8" or a tieback of the 9-5/8" casing may be necessary (example: if the pre-rig MIT-OA or Rig work MIT-OA fails)Should this happen a USIT log will be run to determine the TOC in the 13-3/8"x 9-5/8"annulus. The casing will then be cut above the TOC and pulled. If the OA test fails, the 9-5/8"casing would be tied back to surface using the existing wellhead equipment. In the event that casing is pulled or ran,the BOPE top ram configuration will change to 9-5/8"fixed and then be changed back to 2-7/8"x 5"VBR's. If 9-5/8" is tied back to surface, the 7" casing would be run as a liner with 150' of overlap above the window. The cement job would not change in volume for the liner.

The plug set at 9372'md is set as deep as possible. Debris prevented the plug from being set deeper. 2. The nature of the leak is likely the liner lap at 8490'md. A CMIT-TxIA and a MIT-T passes to 2000 psi.The CMIT- Tx1A fails at 2500 psi with T/IA loss 187/186 psi in 1s`15 min and T/IA lost 103/104 psi in 2nd 15mins for a total of 290/290 psi in 30 mins.The MIT-T fails at 2500psi with Tbg loss of 53 psi in 1st 15min and 45 psi in 2nd 15 min. The IA did not track, a 1000 psi differential was maintained. a. These leak rates indicate a small leak. b. Setting the posiset above the liner lap will isolate the liner lap. A LTP cannot be set due to the restriction in the SSSV nipple at 2157'md. c. A CMIT-TxlA will be performed after the upper cement work is complete verifying the cement and production casing competency before the tubing cut and again after. d. PPPOT-IC passed to 3500 psi e. MIT-OA passed to 1200 psi f. Diagnostics with DHD were performed in Jan and Feb 2016. IA FL and pressure was unchanged during a series of bleeds and monitors,TIO plot. 3.

Thanx, Victoria 1 • • Sundry Application Plug for Re-drill Wells Work Flow This process is used to identify wells that are suspended for a very short time prior to being re- drilled. Those wells that are not re-drilled immediately are identified every 6 months and assigned a current status of"Suspended." Step Task Responsib e 1 The initial reviewer will check to ensure that the "Plug for Redrill"box Geologist in the upper left corner of Form 10-403 is checked. If the "Abandon" or "Suspend" boxes are also checked, cross out that erroneous entry and initial it on both copies of the Form 10-403 (AOGCC's and operator's copies). 2 If the "Abandon"box is checked in Box 15 (Well Status after proposed Geologist�. work) the initial reviewer will cross out that erroneous entry and initial then it on both copies of the Form 10-403 (AOGCC's and operator's copies). Instead, check the "Suspended" box and initial that change. Drilling Engineer The drilling engineers will serve as quality control for steps 1 and 2. (QC) 3 When the Stat Tech receives a Form 10-403 with a check in the"Plug Stat Tech for Redrill" box, they will enter the Typ_Work code "IPBRD" into the History tab for the well in RBDMS. This code automatically generates a comment in the well history that states "Intent: Plug for Redrill." 4 When the Stat Tech receives any Form 10-407, they will check the Stat Tech History tab in RBDMS for the "Intent: Plug for Redrill" code (IPBRD). If present and there is no evidence that a subsequent re-drill has been COMPLETED, the Stat Tech will assign a status of SUSPENDED to the well bore in RBDMS no matter what status is listed on the 10-407. The Stat Tech will also change the status on the 10-407 form to SUSPENDED, and date and initial this change. If the Stat Tech does not see the "Intent: Plug for Redrill" comment or code, they will enter the status listed on the Form 10-407 into RBDMS. 5 When the Form 10-407 for the redrill is received, the Stat Tech will Stat Tech change the original well's status from SUSPENDED to ABANDONED. 6 The first week of every January and July, the Stat Tech and one of the Stat Tech Geologists will check the "Well by Type Work Outstanding"user query Geologist in RBDMS to ensure that all of the Plug for Redrill wells have been handled properly. At this same time, they will also review the list of suspended wells for accuracy.

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.

MAD PASS DATA WERE ACQUIRED OVER THE ENTIRE OPEN-HOLE SECTION WHILE POOH AFTER REACHING FINAL TD. THESE MAD DATA ARE PRESENTED SEPARATELY. 6. LOG AND MERGED DIGITAL DATA (LDWG) ONLY WERE SHIFTED TO A SCHLUMBERGER CASED HOLE GAMMA RAY LOG .RUN IN C-34 ON 11 MAY 2006. THESE DATA WERE PROVIDED BY D.DORTCH (SAIC/BP) ON 17 MARCH 2008, PER DOUG STONER (BP). LOG HEADER DATA RETAIN ORIGINAL DEPTH REFERENCES. MAD DATA WERE CORRECTED (SHIFTED) TO THE MWD DATA. 7. MWD RUNS 1-4 REPRESENT WELL C-34A WITH API#: 50-029-21785-01. THIS WELL REACHED A TOTAL DEPTH (TD) OF 11043'MD/8963'TVDSS. SROP = SMOOTHED RATE OF PENETRATION WHILE DRILLING. SRAT = SMOOTHED TOOL RUNNING SPEED WHEN NOT DRILLING. SGRC = SMOOTHED GAMMA RAY COMBINED. SGRD = SMOOTHED NATURAL GAMMA RAY. SEXP = SMOOTHED PHASE SHIFT-DERIVED RESISTIVITY (EXTRA SHALLOW SPACING). Page 2 c-34a.tapx SESP = SMOOTHED PHljSE SHIFT-DERIVED RESISTIVITY (SHALLOW SPACING). SEMP = SMOOTHED PHASE SHIFT-DERIVED RESISTIVITY (MEDIUM SPACING). SEDP = SMOOTHED PHASE SHIFT-DERIVED RESISTIVITY (DEEP SPACING). SFXE = SMOOTHED FORMATION EXPOSURE TIME. AN 'M' SUFFIX ON CURVE MNEMONICS DENOTES MAD PASS DATA.
