Request: Approval is requested for the P&A of Prudhoe Bay well 14-28A to sidetrack and complete 14-28B. MIT-T Passed to 2000 psi (5/23/2014) MIT-IA Passed to 2000 psi (3/20/2015) MIT-OA Passed to 1200 psi (11/15/2015) PPPOT-T Failed to 5000 psi (11/19/2015) PPPOT-IC Passed to 3500 psi (11/19/2015) Well History: 14-28A was a coil sidetrack drilled and completed in 2011. The well has suffered from low " productivity and high water cut since it was brought online. Intervention operations have been unsuccessful to increase production, so the well has been on long term shut-in. 14-28A has no remaining value as all rational actions to remediate performance have been exhausted. Scope of Work: The sidetrack plan for the 14-28A well includes the following operations. The horizontal lateral has been P&A'd with a 2-3/8" cement retainer set at 11,170', followed by a cement squeeze using 30 bbls of 14 ppg SqueezeCrete cement. Pre-rig, the dummy GLM will be pulled at 8959' MD. A cement plug will be circulated into the tubing and IA, which will bring the top of cement to —7,500' MD. Once the cement has setup, the final top of cement will be determined with a drift run followed by an integrity test of the tubing and inner annulus. Next, the 4-1/2"tubing will be jet cut at—4,000'. The rig will then move over the well and pull the 4-1/2" tubing. A clean out run will then be performed, followed by the setting of an EZSV bridge plug in preparation of the whipstock exit at—3,700' MD. The 7" intermediate casing will be set at the top of the Sag River formation and the 6-1/8" production hole will be drilled in Zone 4 of the Ivishak reservoir. The production liner will be a cemented and perforated. 4-1/2"tubing will then be run to the top of the 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 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 A work)the initial reviewer will cross out that erroneous entry and initial thea/)' / 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. STATE OF ALASKA ALASKA OIL AND GAS CONSERVATION COMfv )N REPORT OF SUNDRY WELL OPERATIONS _ 1.

Submit a well schematic diagram with each 10-407 well completion report and 10-404 well sundry report when the downhole well design is changed. Item 1 a: Classification of Service Wells: Gas Injection,Water Injection,Water-Alternating-Gas Injection,Salt Water Disposal,Water Supply for Injection, Observation,or Other. Multiple completion is defined as a well producing from more than one pool with production from each pool completely segregated. Each segregated pool is a completion. Item 4b: TPI(Top of Producing Interval). Item 8: The Kelly Bushing and Ground Level elevation in feet above mean sea level. Use same as reference for depth measurements given in other spaces on this form and in any attachments. Item 13: The API number reported to AOGCC must be 14 digits(ex: 50-029-20123-00-00). Item 20: Report true vertical thickness of permafrost in Box 20. Provide MD and ND for the top and base of permafrost in Box 28. Item 23: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. Item 24: If this well is completed for separate production from more than one interval(multiple completion),so state in item 1,and in item 23 show the producing intervals for only the interval reported in item 26. (Submit a separate form for each additional interval to be separately produced, showing the data pertinent to such interval). Item 27: Method of Operation: Flowing,Gas Lift,Rod Pump,Hydraulic Pump,Submersible,Water Injection,Gas Injection,Shut-In,or Other(explain). Item 28: Provide a listing of intervals cored and the corresponding formations,and a brief description in this box. Submit detailed description and analytical laboratory information required by 20 AAC 25.071. Item 30: Provide a listing of intervals tested and the corresponding formation,and a brief summary in this box. Submit detailed test and analytical laboratory information required by 20 AAC 25.071.

Disposal: • All drilling and completion fluids and all other Class II wastes will go to Grind & Inject. • All Class I wastes will go to Pad 3 for disposal. Hole size: 3.0" Casing Program: • 2-3/8", 4.6#, L-80, STL Solid Liner 9,250' MD — 12,434' MD ° • A minimum of 15 bbls of 15.8 ppg cement will be used for liner cementing. (TOC 9,250' MD) Well Control: • BOP diagram is attached. • Pipe rams, blind rams and the CT pack off will be pressure tested to 250 psi and to 3,500 psi. • The annular preventer will be tested to 250 psi and 3,500 psi. Directional • See attached directional plan. Maximum planned hole angle is 107°. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property— 12,500'. • Distance to nearest well within pool — 1,600'. Logging • MWD directional, Gamma Ray and Resistivity will be run over all of the open hole section. • Triple Combo Open Hole Logging: Gamma Ray, Induction Resistivity, Density, Neutron. • Cased hole GR/CCL/MCNL logs will be run. Anti-Collision Failures • No Failures Hazards • The maximum recorded H2S level on DS 14 was 590 ppm on well 14-21 on 7/16/1995. • Lost circulation risk is considered High for the fault block drilled in 14-28A. Reservoir Pressure • The reservoir pressure on 14-28A is expected to be 3,295 psi at 8,800' TVDSS. (7.2 ppg - equivalent). • Maximum expected surface pressure with gas (0.10 psi/ft) to surface is 2,415 psi.
