Attachments in Duplicate • • To: Alaska Oil & Gas Conservation Commission From: Zach Browning bp CTD Engineer Date: November 9, 2015 Re: C-21 Sundry Approval Request Sundry approval is requested to plug the C-21 perforations as part of the preparation, drilling and completing the proposed C-21A coiled tubing sidetrack. History of C-21: C-21 was completed as a vertical well perforated in Zone 2 back in 1982. Multiple squeeze and perf jobs were performed and in 2005 a RWO was needed to keep C-21 online. The history of perf/squeeze/reperf has left this well without the ability to control where the flow is coming from and has limited the ability to re-perforate and drain the remaining oil lenses. Re-drilling and cementing — new liner through the build section is proposed and will provide a fresh interval to be logged and selectively perfed. The wellbore has confirmed integrity and is fit for sidetrack. Proposed plan for C-21A: Drill a through tubing sidetrack with the Nordic 2 Coiled Tubing Drilling rig on or around January 25th, 2016. The C-21A sidetrack will be a dual string exit from the existing 3-1/2" liner x 7" liner. A packer whipstock will be set pre-rig allowing isolation from the parent perforations. The planned well kicks-off in lower Zone3, builds through the conglomerates and will land and target reserves in Zone 2A/1 B. The proposed sidetrack is a -3015' horizontal Ivishak producer to be completed with a 2-3/8" L-80 solid liner, cemented in place and selectively perforated. This Sundry covers !Jugging the existing C-21 perforations via the packer whipstock set pre-rig and liner cement lob or liner top packer, if the liner lap pressure test fails (alternate plug placement per 20 AAC 25.112(i)). The following describes the work planned and is submitted as an attachment to Form 10-403. A schematic diagram of the current well and proposed sidetrack is attached for reference. �/ cP�cl�'� ago( /5 6- /ewe`/ el��i�h 10 c/i 11 54,/r/ c// i fi°I ' 710/� 0� 14e ,00� • • • Pre-Rig Work(scheduled to begin December 15th, 2015) 1.

Those wells that are not re-drilled immediately are identified every 6 months and assigned a current status of"Suspended." Step Task Responsible 1 The initial reviewer will check to ensure that the "Plug for Redrill"box Geolo istt 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 A`J =. 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). v 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) V � 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. viS Ogg k WELL LOG TRANSMITTAL FCC E IV ED tau v32015 AO GCC PROACTIVE DIAGNOSTIC SERVICES, INC.

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.

The wellhead pressures were tubing/IA/OA equal to SSV/2290/0 psi on 07/03/08. Due to the constraint of not being able to bleed pressure down to the production system due to the shut-down, the diagnostic work took longer to complete. On 07/13/08, a TIFL failed on IA repressurization overnight confirming TxIA communication. The well has been reclassified as Under Evaluation and placed on a 28-day clock. Operations may allow the IA pressure to continue as is or may return the well to production once the facility is online. The plan forward for the well is as follows: 1. DHD: TIFL -FAILED 2. Slickline: Set dummy gas lift valves 4. DHD: re-TIFL post dummy gas lift valves 10/27/2008 OPERABLE: C-21 (PTD #1820810) for Sustained casing pressure due to TxIA Comm Page 2 of 2 • • A TIO plot and wellbore schematic have been included for reference.

Well house inspections were also conducted. Merv Liddelow was the BPX representative in charge of testing, and performed the tests in a professional manner. Twenty-one weilson C-Pad .were tested with five.failures witnessed. The SSV on well C-04A tripped below 50% of the separator psi, the SSV on well C-07A failed to hold D/P, the pilot on well C-19B was frozen, the pilot on well C-20B failed to trip and the SSV failed to hold DIP. Mr. Liddelow indicated, to me that all failures were repaired within 24 hours. I inspected 21 well houses and noted leaking'wing valves on wells C-03A, C-13A and..'C-19B. A hydraulic fluid leak on the SSV control line of well C-05 and a slight crude oil leak from the SSV on well C-25A were also noted. Mr. Liddelow indicated he would have these items corrected. The AOGCC test forms are attached for reference. SUMMA.R, ,Y: I witnessed the SVS tests on twenty-one oil producing wells on C Pad in the Prudhoe Bay Field. 21 wells tested 42 components, Ii failures witnessed, and 11.9% failure rate. 21 well houses inspected.

Production logs run on C-21 have identified leaking squeezed perforations in the liner between 9027' and 9134' BKB. These perforations have been squeezed twice but the remedial work has failed to stop gas entry. The 3 W' scab liner is to be hung from the XN nipple in the tubing tailpipe and cemented in place with approx. 12.6 bbls cement. The scab liner will then be drilled out and the well returned to production. The. following summarizes the procedure and is submitted as an attachment tc~ Form 10-403. A schematic diagram of the proposed completion is attached. 1. RU slick line and drift for the 3.5" liner. 2. Dummy off GLM's. Liquid pack and PT inner annulus to 2000 psi. 3. Kill well. 4. Cover existing perfs with 20/40 carbolite to 9,145'. Tag to confirm. 5. Run and cement 3.5" ST-L scab liner. PT to 2000 psi. 6. Drill out float equipment. 7.

When injectivity got to 1500 psig at .6 bbl, opened chokes and held 1000 psig on well. Cut cement stage to 8 bbls. Circulated cement down to 9035 and closed chokes when perfs were covered. Pressure ramped quickly 3000 psig then broke back for about 0.5 bbls. Held 3000 psig on squeeze for 45 mins. Jetted excess Maraseal and cement OOH with slick water and 25 bbls of dual polymer. Attempt to jet through interface but was unable. Laid 10 bbls of TEA across perfs. Began to POOH and lost a suction valve. Pump was down for 11 mins for repairs. Ran back in hole to 9010' and jetted liner and tubing while POOH. FP well to 2000'. Final PT was JFT at 550 psig.

SIGNED BY Approved Copy Returned /~- ~__~ ~ Commissioner SUBMIT IN TRIPLICATE STATE SUNDRY APPLICATION WELL C.21 It is planned to cement squeeze well C-21 and reperforate as before. Well C-21 was first squeezed in September 1987 to reduce gas production from an upper perforated interval. The squeezed perforations are now leaking gas sufficiently to warrant a re,squeeze with coiled tubing. The post-workover perforations will be 9,144' - 9,180'MD BKB. The leaking squeeze perforations extend across 9,046' - 9,134'MD BKB. 1. Rig up coiled tubing unit and pressure BOP's to 4000 psi. 2. Surge the perforations with a shear out disk set in tailpipe nipple. 3. Return well to production. 4. Set low fluid loss, non-damaging, sized salt pill across target production interval. Top of salt to be dressed at 9136'MD. 5. Liquid pack wellbore with produced water. 6. Acid wash target squeeze perfs (9046-9134'MD) with acid. 7. Pump cement with surfactant/mutual solvent pre-flush. 8. Perform cement squeeze on leaking perforations (9046-9134'MD). 9. Contaminate cement in the wellbore. 10. Reverse out contaminated cement. 11. Leave well freeze protected and slightly overbalanced with nitrogen filling top ~4000'MD of tubing. 12. Remove salt and place well back on production by releasing trapped nitrogen to low pressure system. Coiled Tubin~ Blow-Out-Preventers Coiled Tubing .
