Request: Approval is requested for the P&A of Prudhoe Bay well S-44 to sidetrack and complete S-44A. MIT-IA Passed to 3,500 psi (10/29/2014) PPPOT-T Passed to 5,000 psi (10/18/2014) PPPOT-IC Passed to 3,500 psi (10/18/2014) Well History: S-44 is currently an Ivishak producer that has a tubing tail fish near the S-44L1 window (been in the hole since 2006 which was mostly a product of the RWO), and a Baker whipstock fish that is located above the 7" x 4-1/2" packer at 9,562' MD (been in hole since 2003). With the exception of the two fish in the hole, the upper completion appears to be in good shape. Scope of Work: The sidetrack plan for the S-44A well includes the following: pre-rig operations will include setting a cement retainer and P&A laterals with 122 bbls of cement. Drift and tag top of cement, pull DGLV from Station 1 at 9,016' MD and circulate a cement plug into TBG x IA (-38 bbls). Drift and tag cement, perform CMIT-IA to 3,500 psi, and jet cut at 3,200' MD. Perform another CMIT-IA to 3,500 psi, install dry hole tree and set TWC. The rig will then move in and pull 4-1/2" tubing, run a clean out run, jet cut 7" casing at 3,000' MD and pull 7" to surface. Once the casing has been pulled, set an EZSV bridge plug in preparation to set the whipstock to exit the casing at -2,747' MD. A 7" intermediate casing will be set at the top of the Kuparuk River and 6-1/8" production hole will be drilled in the Kuparuk. Run 4.5" cementless/sliding sleeve production liner assembly with liner top packer. Run 4.5" tubing tied into top of production liner.

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 v/; 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 y check the "Suspended" box and initial that change. 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.

Subject: S-44L 1 (PTD #1970070) UNDER EVALUATION for sustained casing pressure - TxlA Communication Attachments: S-44L 1.pdf Sent: To: Hi all, Well S-44L 1 (PTD #1970070) has been found to have sustained casing pressure on the IA. The wellhead pressures were /2180/2160/11 psi on 09/03/07. A subsequent TIFL failed the following day on overnight build-up of IA pressure. The well has been reclassified as Under Evaluation and may be produced under a 28-day clock. The plan forward for this well is as follows: 1. D: TIFL - FAILED 2. APE: Eval DGL V design ~. 3. S: Set DGL Vs 4. D: Re-TIFL A wellbore schematic has been included for reference. «S-44L 1.pdf» Please call with any questions or concerns. Thank you, Jlnna (])u6e æ f£.
