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.

MU and run 4-W 13.5# 13CR VT sliding sleeve/swell packer liner to TD. 33. Drop a ball to land the ball on the ball seat in the toe of the well. 34. When the ball lands, set liner hanger and liner top packer. Prior to pulling the running tool, perform a pressure test on the liner top packer by testing the 7" casing x drill pipe annulus to 250 psi low/3,500psi high for 5 min low/30 min high. 35. Pull liner running tool above liner top. Displace well to clean 10.3 ppg Brine. 36. POH, L/D the liner running tool. 37. R/U and run a 4-%", 13.5#, 13CR, VAMTOP tubing completion with GLMS. Space out and land the tubing with tubing tail inserted into the liner tieback sleeve. 38. Make up tubing hanger per Cameron Rep. Land the tubing hanger, and run in lock down screws. 39. Reverse circulate filtered 10 ppg brine and corrosion inhibitor into the tubing x casing annulus. 40. Drop ball/rod and set packer and individually test the tubing and annulus to 3,500 psi for 30 minutes. Record each test. 41. Bleed tubing pressure to 2,000 psi. Pressure test the IA to 250 psi low/3,500 psi high for 5 minutes low/ 5 minutes high. 42. Hold pressure on the IA and bleed tubing pressure to zero, shearing the DCK shear valve. Pump both ways to confirm circulation ability. 43. With landing joint still rigged up, reverse circulate diesel freeze protect using rig injection pump. 44. Allow diesel to U-tube, drain stack, and rig down landing joint. Monitor well for 1 hour to confirm well is dead. 45. Install TWC and test from above to 250 psi low/3,500 psi high for 5 minutes each and from below to 250 psi low/ 3,500 psi high for 5 minutes low/30 minutes high. 46. Nipple down the BOPE. Nipple up the adaptor flange and double master valves and test to 5,000 psi with diesel. 47. Ensure Heet® is left on top of the TWC and only diesel (no water) is left in the tree. 48. Install all annulus valves and secure the well. Ensure T/IA/OA all have two barriers in place. 49. RDMO. Planned Post-Rig Operations: 1. Pull BPV, Pull Ball, Rod and RHC Plug with slickline. 2. Pull shear valve and dummies, install GLVs. 3. Open sliding sleeves as required by NWD PE. Flow back and clean up the well. 4. Install flow lines and well house. 5. Produce for—1 month to determine pre-frac PI. 6. Post pre-frac PI determination, conduct fracture stimulation.

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. 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.
