Attachgrerits in Duplicate • • • To: Alaska Oil &Gas Conservation Commission From: Ryan Ciolkoszz0 0 CTD Engineer Date: October 3, 2016 Re: 07-19A Sundry Approval Sundry approval is requested to plug the 07-19A wellbore as part of the drilling and completion of the proposed 07-19B CTD sidetrack. 07-19A, is a Z2A/2BI horizontal well that was drilled in early 1998. Initial rates were close to 3000 bopd and the well produced full time for about 2 years until it was shut-in for integrity problems in mid-2005. The well was repaired and returned to production in late 2006 and it demonstrated strong re-charge producing full- time for almost 1.5 years.. Finally in 2014 a well work intervention attempted to mill the cibp but was unsuccessful and had to be aborted. This left the well with no remaining well work options. Currently the well has no remaining value. Proposed plan: Drill a through tubing sidetrack with the Nordic 2 Coiled Tubing Drilling rig on or around November 15st, 2016. Nordic 2 will mill a 3.80"window in the 7" liner and drill 4-1/4 hole to the top of the sag river at 10,862 ' MD. MU 3-1/4" Liner run and set. Drill 3.25 at TD at 13,590' MD. The lateral will be completed with a 2-3/8" L-80 liner which will be cemented and perforated. This Sundry covers plugging the existing 07-19A perforations via the 07-19B liner cement iob or liner top packer set post-rig (alternate plug placement per 20 AAC 25.112(i)) and via posi-set plug. The following describes work planned and is submitted as an attachment to Form 10-403. A schematic diagram of the current wellbore and proposed sidetrack is attached for reference. 004, /4_s ,61. �� 20/6 e / y�r�S /5' 4SIC-, /677 CliC/C ,1 co�c�f• --14e we an' D� rfee- INC// � /`j ` 4 f r 7J 14e 4,0 (off 444f cre4,1 q(fb been 4,,/ obi t,^vireA �l ' qtr we nOn -COPfe 'ti re and ire (re 41'1 water Celt ,•no(:C at-5 c O J 1 / �YF awGiy from �(t{ a5 yi6d1U rob j 47� e Ur fUe&01 of ?41 .' f'� �;ke /�Iif 81/ 1 y io dct'ay L rti a PU 4'0- GAP it 4bve �°d , r ►1, rv�' 9 11°A ©f f e rQ �I, ; ll Stool d all is �ro"d /e GD' ` fpr Pool, /°/9/ • • CTD Drill and Complete 07-19B program: Pre-Rig Start Date: Oct 15st, 2016 Pre-Rig Work 1.

Those wells that are not re-drilled immediately are identified every 6 months and assigned a current status of"Suspended." Step Task Responsib 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 V 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.

As the attached AOGCC BOPE Test report shows there were 2 failures. The Blind Shear rams failed to pressure test, these were replaced and failed a second time. A __ __ closer inspection of the BOP body cavity revealed a defect in the sealing su. rface_ that will require extensive repairs-. The lower ~ 7/8" pip(~ ram~i-~vhich are no longer needed on this well, were replaced with straight blind rams and tested OK. The Blind / Shear Rams were left in place to maintain the capability to shear pipe. Upon completion of this well the failed ram body will be sent to the manufactuer for repair. The second failure was the Hyd. Choke which would not function properly from the control panel on the rig floor. Parts are on order to repair the choke panel, and will be installed before beginning operations on the next well. The rig and Coil tubing unit were clean and all related equipment appeared to be in good working order.
