History of 18-07: 18-07 was originally completed in 1982. In 2000, the tubing was replaced by RWO. A CTD sidetrack to 18-07A was completed. The well reached MGOR and while it showed some recharge, the last cycle lasted only 4 days before testing at MGOR. In July 2013, the liner top packer was re-set in an attempt to reduce gas production. The liner top packer re-set was unsuccessful in changing the production trend. The lack of recharge and high GOR leave 18-07A with no significant remaining value. In October 2014, a CTD sidetrack (18-07B) was attempted but had to be suspended during the drilling Pase due to ex reme ui• • - . is is a new we p an a wi access the same targe •ut kicks off-400' shallower to avoid he fault that was crossed and caused the losses in 18-07B. • jIn re f d'yps (pt"es'- /f ec1ffp y e #;//, Proposed plan for 18-07C: Drill a through tubing sidetrack with the Nordic 2 Coiled Tubing Drilling rig on or around September 22nd, 2015. The 18-07C sidetrack will be a dual string exit from the existing 4-1/2" tubing and through the 7" liner. The kick-off is in the Shublik and will target reserves in Zone 1A. The proposed sidetrack is a -3195' horizontal Ivishak Zone 1A producer to be completed with a 3-1/2" x 3-1/4" x 2-7/8" L80 solid liner, cemented in place. This Sundry covers plugging the existing 18-07B side track attempt via the 4-1/2" KB packer whipstock set pre-rig and 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. • S Pre-Rig Work(scheduled to begin August 15, 2015) 1. E Drift for and Set 4-1/2" Packer WS 2.

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 in the Patricia or Steve • 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 Patricia or Steve work) the initial reviewer will cross out that erroneous entry and initial it on both copies of the Form 10-403 (AOGCC's and operator's copies). Instead, then check the "Suspended" box and initial that change. V Guy or Victoria 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 for Jenni 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 History tab Jenni 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 change Jenni 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 Jenni Geologists will check the "Well by Type Work Outstanding" user query in Patricia or Steve 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. 171V 214- —O!9- • • Loepp, Victoria T (DOA) From: Loepp,Victoria T (DOA) Sent: Monday,August 10, 2015 1:24 PM To: 'Lastufka,Joseph N' Subject: RE: Sundry for 18-07B (PTD#214-017) Verbal approval is granted to set the whipstock in 18-07B.

The 18-07B sidetrack will be a dual string exit through the existing 4-1/2" tubing and 7" liner and kick off in the Shublik at 51 degrees inclination, build and land in Zone 1A. The proposed sidetrack is a —3195' horizontal Zone 1A producer, which will target Zone 1A in western DS-18, just north of the Mid-field graben. The lateral will be completed with a 3-1/2" x 3-1/4" x 2-7/8" L-80 solid liner and will be cemented to the top of the liner at 11,590' MD and selectively perforated. The existing perf intervals and initial 18-07B sidetrack attempt are below the KOP and will be isolated via the packer whipsto R set pre-rig and the liner cement job or liner top packer. The initial 18-07B sidetrack attempt in October 2014 was suspended due to extremely high fluid losses. The KOP for this sidetrack is —400' higher than the initial attempt arid should allow us to avoid the fault crossing where losses were encountered. Pre-Rig Work(scheduled to begin August 15,2015) 1. E Drift for and Set 4-1/2" Packer WS 2. F MIT—T to 2500 psi 3. V Bleed wellhead pressures to zero. 4. V Bleed production, flow and GL lines down to zero. 5.

Drilling operations were halted do to the increasing loss rate, and inability to be in conformance.The well was freeze protected, and secured with a TWC before the rig moved off. The original completion is still competent and was not altered above the w' original production packer. All work was conducted below the production packer in the production liner/in zone. There is no plan to P&A this well, however there is no clear line of sight as to when we could return or if this will become a rotary sidetrack instead. Please let me know if there is anything else you need answered and I will get it for you. I will also try to work with Jan to get an update well bore schematic if you need one.

We were not able to meet the obligations of our GP 10-10 deviation that say we will not drill with a loss rate of more than 5 bpm. Our intention is to return to this well and complete it as planned, but we will need to revise the deviation first. Thanks, David Johnston BP Exploration(Alaska), Inc.

I was not able to determine if we notified you of that change over the weekend so I thought it best to do so regardless. Also, my Well Site Leader found an error on my part with my application. In my procedures for perforating I told you we would: Perforating: • SWS 1-1/16", 6 spf, perf guns, 1" CSH work string, & 2-1/16" PH6 • The primary barrier for this operation: a minimum EMW of 8.4 ppg. • A X-over shall be made up to a safety joint including a TIW valve for all tubulars ran in hole. Those are for our"slim hole designs, and we will be using our big coil so, In reality we will be: Perforating: • SWS 2", 6 spf, pert guns, 1-1/4" CSH work string, & 2-1/16" PH6 • The primary barrier for this operation: a minimum EMW of 8.4 ppg. • A X-over shall be made up to a safety joint including a TIW valve for all tubulars ran in hole.
