Parent well, 07-15A, is a horizontal in Z1 B with a Z2A toe-up that was drilled in late 1998. The well was completed with 1410' of 1B perforations and 100' of 2A in the toe. Currently the well is a swing well producing at 85,000 gor and is uneconomic with no remaining well work options07-15A wellbore does not have any existing value left. Proposed plan: Drill a through tubing sidetrack with the Nordic 2 Coiled Tubing Drilling rig on or around November 1st, 2016. E-line unit will set a CTD whipstock. Nordic 2 will mill a 3.80"window in the 4-1/2" liner and drill an Ivishak well to 11,601 ' MD. The lateral will be completed with a 3-1/2" x 3-1/4' x 2-7/8" L-80 liner which will be cemented and perforated. This Sundry covers plugging the existing 07-15A perforations via the 07-15B liner cement lob 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.

Those wells that are not re-drilled immediately are identified every 6 months and assigned a current status of"Suspended." Step Task Responsib e 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 7"p 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, 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.

If Class I wastes are generated, they will be taken to Pad 3 disposal site. Bottom hole pressure is 3,323 psi at 8,360' TVDss (estimated) Maximum shut-in casing pressure is 2,487 psi (assumes 0.1 psi/ft gas gradient to surface). Drilling Discussion Well Objective This sidetrack will target a 2,200' horizontal section in the deepest producible Romeo sands beginning approximately 200' NE of the current bottomhole location. An effective NLOC of 41' is prognosed for the proposed horizontal sidetrack in the 14P/21P sand intervals. An additional 28' of effective NLOC in the Tango sands (25P) will be targeted in the build section. This sidetrack may increase stand-off from GOC by as much as 40'. Anticipated average initial rate is 950 BOPD. Expected incremental recovery is 1.1 MMBO. Drillinc~ Objective The objective is to cut and pull the existing 5 ~" completion tubing above the 9 5/8" x 5 1/2" completion packer @ 8,257 ft (cut _+ 25ft above packer) , mill window via whipstock in the 9 5/8" casing @ 8,000' MD, directionally drill 8 1/2" hole through the Kingak shale to TD + 8,603' (10' into the Sag River); run, cement and test 7" liner. Directionally drill 6" hole out of the 7" shoe to horizontal at + 9,730' MD. Run DPC logs. Geosteer through Z1 sands to TD at + 11,762'. The well will be completed as a Zone 1 producer with a 4 1/2", L-80, 12.6# solid liner x 4 12.6#, L-80, tbg with (3) GLM's and EOA tailpipe assy. The GLM's will be run with depths determined after log evaluation. DRILLING HAZARDS AND CONTINGENCIES Always have two levels of tested isolation before NU/ND. SURFACE CLOSE APPROACH WELL SHUT-INS Adjacent well 7-37 will need to be shut in during the rig move. 7-37 is spaced 35' from well 7- 15. Careful coordination with any ongoing pad or facility operations or activities will be initiated prior to commencing the rig move. DRILLING CLOSE APPROACH WELL SHUT-INS No shut-ins identified on Sperry Sun directional well plans due to close approach requirements. PORE PRESSURE: Pore pressure in the Kingak Shale is expected to be 9.5 EMW. The Kingak section will be drilled using 10 ppg mud due to shale mechanical instability. The mud weight will provide sufficient overbalance to reservoir pressure and not too high of an overbalance to create lost circulation while drilling the shale. The pore pressure in the Sag River (7" liner shoe) is expected to be near 7.7 ppg EMW and the Sadlerochit is expected to be near 7.8 ppg EMW. 8.7 - 8.8 ppg mud will be used drilling out of the Sag River and through the Sadlerochit zones and will provide sufficient overbalance to the reservoir pressure.. HOLE PROBLEMS There are no obvious or expected hole problems drilling this well. No faults observed or mapped within 300' of the proposed wellbore. 40-50' throw faults mapped 300-500' NE and SW of the latter portion of the wellbore target. The Kingak shale will be drilled with 10 ppg mud at 0° inclination. Casinq Shoe Kick Tolerance The smallest kick tolerance for the casing shoes is calculated as 26.8 bbls of influx assuming a swabbed gas influx at the bottom of the Put River formation along the planned directional path. Based on 10.0 ppg MW (Put River 8,040' MD & 7,874' TVD 9.1 ppg reservoir pore pressure), and min. frac at the 13 3/8" shoe 12.0 ppg. Pre-Rig Work 1.

If Class I wastes are generated, they will be taken to Pad 3 disposal site. Bottom hole pressure is 3,323 psi at 8,360' TVDss (estimated) Maximum shut-in casing pressure is 2,487 psi (assumes 0.1 psi/ft gas gradient to surface). Drilling Discussion Well Objective This sidetrack will target a 2,190' horizontal section in the deepest producible Romeo sands beginning approximately 200' NE of the current bottomhole location. An effective NLOC of 41' is prognosed for the proposed horizontal sidetrack in the 14P/21P sand intervals. An additional 28' of effective NLOC in the Tango sands (25P) will be targeted in the build section. This sidetrack may increase stand-off from GOC by as much as 40'. Anticipated average initial rate is 950 BOPD. Expected incremental recovery is 1.1 MMBO. Drilling Objective The objective is to cut and pull the existing 5 ½" completion tubing above the 9 5/8" x 5 1/2" completion packer @ 8,257 ft (cut + 25ft above packer) , mill window via whipstock in the 9 5/8" casing @ 8,000' MD, directionally drill 8 1/2" hole through the Kingak shale to TD _+ 8,602' (10' into the Sag River); run, cement and test 7" liner. Directionally drill 6" hole out of the 7" shoe to horizontal at _+ 9,400' MD. Run DPC logs. Geosteer through Z1 sands to TD at _+ 11,620'. The well will be completed as a Zone 1 producer with a 4 ~'' y2 , L-80, 12.6# solid liner x 4 ½" 12.6#, L- 80, tbg with (3) GLM's and EOA tailpipe assy. The GLM's will be run with depths determined after log evaluation. DRILLING HAZARDS AND CONTINGENCIES Always have two levels of tested isolation before NU/ND. SURFACE CLOSE APPROACH WELL SHUT-INS No wells need to be shut in because of the rig move. Adjacent well 7-37 is 34.57' spacing to the North and adjacent well 7-33 is 59 71' svacina to the South Careful coordination ~$~a.~a(~r~-~ pad or facility operations or activities will be initiated prior to commencing the rig m09¢? ........ - DRILLING CLOSE APPROACH WELL SHUT-INS No shut-ins identified on Sperry Sun dkectional well plans due to close approach r~g~ents. PORE PRESSURE: Pore pressure in the Kingak Shale is expected to be 7.7 EMW. The Kingak section will be drilled using 10 ppg mud due to shale mechanical instability. The mud weight will provide sufficient overbalance to reservoir pressure and not too high of an overbalance to create lost circulation while drilling the shale. The pore pressure in the Sag River (7" liner shoe) is expected to be near 7.7 ppg EMW and the Sadlerochit is expected to be near 7.8 ppg EMW. 8.7 - 8.8 ppg mud will be used drilling out of the Sag River and through the Sadlerochit zones and will provide sufficient overbalance to the reservoir pressure.. HOLE PROBLEMS There are no obvious or expected hole problems drilling this well. No faults observed or mapped within 300' of the proposed wellbore. 40-50' throw faults mapped 300-500' NE and SW of the latter portion of the wellbore target. The Kingak shale will be drilled with 10 ppg mud at 0° inclination. Casing Shoe Kick Tolerance The smallest kick tolerance for the casing shoes is calculated as infinite of influx assuming a swabbed gas influx at the bottom of the Sag River along the planned directional path. Based on 8.7 ppg MW (TSAG 8,602' MD & 8,433' TVD 7.5 ppg reservoir pore pressure), and min. frac at the window 10.0 ppg. The casing shoe will withstand complete (gas) evacuation to surface based on predicted pressures. Pre-Rig Work 1. RU slickline and drift thru 3 1/2" CT liner to CIBP at 9,171 '.
