(7 • • • To: Alaska Oil & Gas Conservation Commission From: Zach Browning b./ p CTD Engineer 0' Date: July 13, 2017 Re: 15-32B Sundry Approval Request Sundry approval is requested to plug the 15-32B perforations as part of the preparation, drilling and completing the proposed 15-32C coiled tubing sidetrack. History of 15-32B: 15-32B was completed as a CTD sidetrack in 2010. The well was a full time producer into 2012 and cycled until mid 2013 when an unsuccessful GSO squeeze was performed to eliminate a suspected mid lateral gas entry. A plug was set following the failed squeeze and 90' of perfs were added in the heel. The well continued to produce until it recently reached MGOR. The well is no longer competitive and has no future wellwork options. The well passed integrity screening and is fit for sidetrack. Proposed plan for 15-32C: Drill a through tubing sidetrack with the Nabors CDR2 Coiled Tubing Drilling rig on or around October 1st, 2017. During pre-rig operations cement will be placed between the 4-1/2" tubing and 7" liner below the production packer to prepare for a dual string exit. A monobore whipstock will be then be set on eline. The rig will mill a 3.80" window and kick-off in Zone 4. The well is planned to cross the conglomerates and land at the base of Zone 1 targeting reserves in Zone 1A in - a 70 acre target southwest of DS 15. The proposed sidetrack is a -2700' horizontal Ivishak producer to be completed with a 3-1/4" x 2-7/8" L-80 solid x slotted liner with a modified bonsai cement job. If losses or faults/fractures are seen in the last 500', solid pipe is planned as a contingency and will be cemented and selectively perforated. This Sundry covers plugging the existing 15-32B perforations via the cement retainer and cement placed pre rig, and the liner cement job 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.

Those wells that are not re-drilled immediately are identified every 6 months and assigned a current status of"Suspended." Step Task Responsiblet 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 .b 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. • Wallace, Chris D (DOA) From: AK, D&C Well Integrity Coordinator <AKDCWellIntegrityCoordinator@bp.com> Sent: Saturday, May 14, 2016 6:49 PM To: AK, OPS FS3 OSM;AK, OPS FS3 Facility OTL; AK, OPS FS3 Field OTL; AK, OPS FS3 DS Ops Lead;AK, D&C Well Services Operations Superintendent; AK, D&C Wireline Operations Superintendent; Cismoski, Doug A; Daniel, Ryan; AK, RES GPB West Wells Opt Engr;AK, RES GPB East Wells Opt Engr; AK, OPS PCC EOC IL;AK, OPS PCC Ops Lead; G GPB FS3 Drillsites;Igbokwe, Chidiebere; Regg, James B (DOA) Cc: AK, D&C DHD Well Integrity Engineer; AK, D&C Projects Well Integrity Engineer; AK, OPS FF Well Ops Comp Rep; Sternicki, Oliver R; Pettus, Whitney; Sayers,Jessica; Dickerman, Eric; Morrison, Spencer; 'chris.wallace@alaska.gov' Subject: OPERABLE: Producer 15-32B (PID# 2100620) Passed MIT-IA All, Producer 15-32B (PTD#2100620) passed an MIT-IA on 05/13/16, and is reclassified as Operable.
