Attachments in Duplicate ,//rb /C/c74 • • To: Alaska Oil & Gas Conservation Commission ti From: Jacob Leemhuis by CTD Engineer Date: November 10, 2016 Re: 15-16B Sundry Approval Request Sundry approval is requested to plug the 15-16C perforations as part of the preparation, drilling and completing the proposed 15-16C coiled tubing sidetrack. History of 15-16B: 15-16B is a Rotary Zone 1A horizontal sidetrack which was initially put on production April 2010. - In 2001 a PPROF indicated 90% of gas was from the well's heel perfs. An organoseal squeeze was performed in 2014 and was a very successful GSO, eliminating 30 mmscf/d. The GOR increased gradually to marginal causing the well to be shut-in for HGOR in 2015. A CIBP was set in 2016 to shut off the structurally higher toe perfs but the well returned to marginal GOR production within one month. An attempt was made to cycle the well following a period of three months shut-in but the well was immediately above MGOR. All well work options have been exhausted and the well is deemed to have no remaining value. • Proposed plan for 15-16C: Drill a through tubing sidetrack with the Nordic 2 Coiled Tubing Drilling rig on or around December 15th, 2016. The 15-16C sidetrack will be a single string exit from the existing 4-1/2" liner. A packer whipstock will be set allowing isolation from the parent perforations. 15-16C will kickoff from 4-1/2" liner drilling a horizontal well to provide offtake in the target fault block across the • Zone 1A sands. Well design involves kicking off a 4-1/2" packer whipstock, drilling build section with 20 DLS landing prior to crossing fault#1, drilling lateral with 12 DLS geosteering above BSAD as needed, run 3-1/2" x 3-1/4" x 2-7/8" L-80 production liner, cemented and perforated. This Sundry covers plugging the existing 15-16B perforations via the packer whipstock 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.

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 / 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. i w .. 0 N Produced Gas (Thousand Cubic Feet ("MCF") per Day) or Gas-Oil Ratio (MCF per Barrel) 0 0 O O 0 0 0 0 0 0 0 0 •p 0 0 0 0 0 0 0 0 0 0 - o - . 01 CO N U3 U11 Cr M N 0 0 �i 1 I/ �i 9l z/ O I iiib, v) ib ro( 0 O =7„ 2ro ililiniiii- 4>. on> = to .— SI%i O 0C7 -- In 1111.""--1111.""-- v� O 0 13 o ! : Z: CO celaillim o 11 ' P O m - ► �l LA 0 I-I 3 N.

During rig operations, the 4 -1/2" x 3 -1/2" tubing will be pulled. The whipstock exit from the 9 -5/8" casing is estimated at 4600' MD and will be milled using an 8 -1/2" milling assembly. The 8 -1/2" hole will be drilled to the Top of the Sag River where a 7" liner will be run and 1000' of cement will be pumped. The pj(,+- production hole will be drilled with a 6 -1/8" BHA initially penetrating through the lvishak H -- into the Kavik. An openhole sidetrack will then be performed in Zone 2 of the lvishak p ktM, ci and building to horizontal in Zone 1A. The well will then run horizontal) through the Ivishak formation. The liner will be a 4 -1/2" L -80 liner and the u 'rig will be 4 -1/2" ./ 7'e1 13Cr, tied into the top of the production liner.

While drilling the intermediate section the Put River formation is expected to be 10.2 ppg EMW. B. The Ivishak in this fault block is expected to be 7.08 ppg EMW. This pressure is estimated based on offset well pressures. 3500 psi test pressure is in accordance with the RP for Prudhoe production well casing tests for producing wells. 11. Lost Circulation/Breathing A. Drill Site 15 is in the med risk zone for LC according to the WURD lost circulation study. There are 2 expected fault crossings in the planned wellbore. Both faults will be encountered in the production section and the lost circulation potential is considered moderate B. In the recently drilled 15 -29B sidetrack to the NW, we did experience severe breathing issues while in the Colville. 111. Kick Tolerance /Integrity Testing A. With the planned mud weights, the kick tolerance for the intermediate section is 50 bbls, and for the production section is infinite. The FIT /LOT will prove up adequate formation strength for expected ECD's. B.
