'''.> r•(7-//e:- ,,, . . ��� ��� �� �� To: Alaska Oil & Gas Conservation Commission From: JanobLeennhuiw bpCEnginaer ~ � Date: May 5, 2016 Re: D-20 Sundry Approval Request Sundry approval is requested to plug the D-20 perforations as part of the preparatimn, drilling and completing the proposed 0-20A coiled tubing sidetrack. History of D-20: D-20 was drilled and completed in May 1982. targeting Zone 2. Multiple mud & HCL acid treatments were done earlin its life. An August 1998 squeeze of the 7" liner proved unsuccessful with the well returning to high gas rates and a September 1998 STP confirming the liner was still leaking. Therefore, in April 1999 a 3-1/2" scab liner was run to 10,036'MD to isolate the leaking 7" liner. A RWO was performed in 2006 to replace the tubing and restore integrity. The well was SI at the end of 2011 after several inconclusive K8|T-|As, then re-did the MIT-T8^ MIT-IA when the passing . criteria was revised and had passing MIT's. When pulling the plug to bring the well back to production, the tool got stuck and was left in hole. Operations choked back the well to minimize the . risk of blowing the toolstring uphole. Then in May 2013, a tool catcher was installed and the choke was opened returning the well to full-time production. In April, 2015 the well's gas rate shot up and a subsequent Pprof indicated the gas entry was from a hole in the liner just below the scab liner. In November of 2015, a video log was run in the well. The scab liner indicated a reduced ID due to buildup of some sort. The gas entry is at the base of the scab liner, either in the liner itself or just below the liner. Fill/fish was seen in the liner across most of the open perfs and there is indication of wire line coming out of the fill (part of the fish). A subsequent review of the fishing and wellwork options established a low probability of success. ' Proposed plan for D-20A: Drill a through tubing sidetrack with the Nordic 2 Coiled Tubing Drilling rig on or around September 15th, 2016. The D-20A 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. D'20 is a slant style well kicking off in Zone 4 with TD in lower Zone 2. The proposed sidetrack is a —751' slant Ivishak producer to be completed with a 2-3/8" 1 3Cr-80 solid liner, cemented in place and selectively perforated post rig. This Sundry covers pluqqinq the existing D-20 perforations via the packer whipstock set pre-riq and liner cement job or liner top packer, if the liner lap pressure test fails (alternate pluq 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. _4' - • :�� - ~�� �/ ' «~ � ' '7- '�� - /� ' / /col 9 (0p( y/� - ` r ' c7� �� 7 /�,/y2 C�r_� �� �J�� �� ' ~J� Crv� ~�/� 3C/{) ��'/ � ' � '°�/ " � 7C7 '"�_ ~ A/} �n/��,� ��// ��y/ / /���� , The /�J /�� �n� m,4�r 7(] - ~ +''.� ~ ' ^'''`° ° //`°r/« ~e -for +�J °/�// Of-- /`�/ ���//�,/_ 1041 'CM �»o' ��r /�~ /���'�,./ �+ ��L � �� E,„,_ r�0v(� ���� ��� ��� � �� emlei' �� °� '� w~^' �.! , �^�V/ l- / /�� / '�/ ^/ '/� �J //�*' �' � /�r�\� - � ��c0/fy� � �/» ��/ '° � ' — ' ' " ',Y~ ' -- ' /~ ' `v eorf'' 0w /t'C p / �NN� �� Pre-Rig Work(scheduled to begin June 1st, 2016) 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 Geologist Sh, 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, she 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, she 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, she 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 in RBDMS to ensure that all of the Plug for Redrill wells have been Geologist handled properly. At this same time, they will also review the list of suspended wells for accuracy. RECEIVED 411 2-(0 5 c) 6 MAR 2 2 201 WELL LOG TRANSMITTAL#902904336 AOGCC To: Alaska Oil and Gas Conservation Comm.

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. If you require any additional information, please contact me or my alternate, Jerry Murphy, at 659 -5102. Sincerely, Torin Roschinger BPXA, Well Integrity Coordinator BP Exploration (Alaska) Inc.

D-20 has a confirmed leak in the PBR above the tubing production packer at 9050' MD. The leak was found 1/22/00 and D-20 was shut-in. D-20 is a GDWFI well in Southern D-Pad. Two nearby wells, D-21 and a 1999 sidetrack, D-09A, produce over 1000 BOPD at 10-15,000 GOR. We would like a variance to flow D-20 to add perforations. If the add perforations increases oil rate, we will fix the PBR leak. If they do not, we will sidetrack the well and tie the production liner back above the leaking PBR. RECEIVED 3 0o0 Oil&GasCons.

Production logs run on D-20 have identified leaks in the liner at 9950-9970 BKB. These leaks are in the gas cap above all perforations. The 3 %" scab liner is to be hung from the XN nipple in the tubing tailpipe and cemented in place with approx. 10 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 to 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 10,055'. Tag to confirm. 5. Run and cement 3.5" ST-L scab liner. PT to 2000 psi. 6. Drill. out float equipment. 7.
