Well Name and Classification (Requirements of 20 AAC 25.005(1) and 20 AAC 25.005(b)) The proposed laterals described in this document are 1C-23L1, 1C-23L1-01, 1C-231-1-02, 1C-23L1-03, 1C- 231-1-04, 1C-231-1-05. All laterals will be classified as "Development -Oil' wells. 2. Location Summary (Requirements of 20 AAC 25.005(c)(2)) These laterals will target the C sand package in the Kuparuk reservoir. See attached 10-401 forms for surface and subsurface coordinates of each of the laterals. 3. Blowout Prevention Equipment Information (Requirements of 20 AAC 25.005 (c)(3)) Please reference blowout prevention (BOP) schematics on file with the Commission for Nabors CDR3-AC. BOP equipment is as required per 20 AAC 25.036 for thru-tubing drilling operations. — Pipe rams, blind rams and the CT pack off will be pressure tested to 250 psi and to 3,500 psi. Using the maximum formation pressure in the area of 3750 psi in 1 C-14A (i.e. 11.7 ppg EMW), the maximum potential surface pressure in 1C-23, assuming a gas gradient of 0.1 psi/ft, would be 3,105 psi. See the "Drilling Hazards Information and Reservoir Pressure" section for more details. — The annular preventer will be tested to 250 psi and 2,500 psi. 4. Drilling Hazards Information and Reservoir Pressure (Requirements of 20 AAC 25.005 (c)(4)) Reservoir Pressure and Maximum Downhole Pressure (Requirements of 20 AAC 25.005 (c)(4)(a)) The formation pressure in KRU 1 C-23 was measured to be 3055 psi (9.0 ppg EMW) on 1/10/2015. The maximum downhole pressure in the 1C-23 vicinity is the 1C-14A at 3750 psi or 11.7 ppg EMW. Potential Gas Zones (Requirements of 20 AAC 25.005 (c)(4)(b)) No specific gas zones will be drilled; gas injection has been performed in this area, so there is a chance of encountering gas while drilling the 1C-23 laterals. If significant gas is detected in the returns the contaminated mud can be diverted to a storage tank away from the rig. Potential Causes of Hole Problems (Requirements of 20 AAC 25.005 (c)(4)(c)) The major expected risk of hole problems in the 1 C-23 laterals will be differential sticking. The relaxation method will be used to free differentially stuck pipe, as shale stability is not a major concern in the C Sand, 5. Procedure for Conducting Formation Integrity tests (Requirements of 20 AAC 25.005(c)(5)) The 1 C-23 laterals will be drilled under 20 AAC 25.036 for thru-tubing drilling operations so a formation integrity test is not required.

Diverter System Information (Requirements of 20 AAC 25.005(c)(7)) Nabors CDR3-AC will be operating under 20 AAC 25.036, for thru-tubing drilling operations. Therefore, a diverter system is not required. 8. Drilling Fluids Program (Requirements of 20 AAC 25.005(c)(8)) Diagram of Drilling System A diagram of the Nabors CDR3-AC mud system is on file with the Commission. Description of Drilling Fluid System - Window milling operations: Water based Power-Vis milling fluid (8.6 ppg) - Drilling operations: Water based Flo -Pro drilling mud (8.6 ppg). This mud weight will not hydrostatically overbalance the reservoir pressure, overbalanced conditions will be maintained using MPD practices described below. - Completion operations: BHA's will be deployed using standard pressure deployments and the well will be loaded with 11.8 ppg sodium bromide completion fluid in order to provide formation over -balance and maintain wellbore stability while running completions. Managed Pressure Drilling Practice Managed pressure drilling (MPD) techniques will be employed to maintain a constant overbalanced pressure on the open hole formation and promote wellbore stability throughout the coiled tubing drilling (CTD) process. Mud weight is not, in many cases, the primary well control barrier. This is satisfied with the 5000 psi rated coiled tubing pack off and MPD choke. BOPE equipment provides the secondary well control as detailed in section 3 "Blowout Prevention Equipment Information".

We will target an EMW at the window of whatever formation pressure we see while drilling, with 11.7 ppg as the maximum expected. The constant BHP target will be adjusted through choke pressure and/or mud weight increases to maintain overbalanced conditions if increased reservoir pressure is encountered. Additional choke pressure or increased mud weight may also be employed for improved borehole stability. Any change of circulating friction pressure due to change in pump rates or change in depth of circulation will be offset with back pressure adjustments. 21 &" 4 r, )-2 %A/; 4 .A, ii zraq° KAn r,.rdn' TVI71 LJsina MPD ICSJUICdluIG I%I- YYIt14VYv �,--•- -- -- Pumps On (1.5 b m) Pumps Off C-sand Formation Pressure (9.0 ppg) 3055 psi 3055 psi Mud Hydrostatic 8.6 2925 psi 2925 psi Annular friction i.e. ECD, 0.080 si/ft 1085 psi 0 psi Mud + ECD Combined 4010 psi 2925 psi (no choke pressure) (overbalanced -955 psi underbalanced -130 psL Target BHP at Window (11.7 ) 3980 psi 3980 psi Choke Pressure Required to Maintain 0 psi 1055 psi Ter et SHP 9.

Proposed Drilling Program (Requirements of 20 AAC 25.005(c)(13)) Summary of Operations Background Producer 1 C-23 is located in the southeast portion of the Kuparuk River field. This well produces only from the C-Sands, as the A -Sands are below the oil water contact in this area. This project seeks to improve the C-Sand throughput and ultimate recovery in the area via six CTD laterals out of producer 1C-23. These laterals will be drilling in two directions - to the southwest and northeast - and will be stacked in the C3/C4-Sands. Nabors CDR3 will set a whipstock and mill a 2.80" window off the whipstock at 13,590'. Three laterals will be drilled to the southwest and three to the northeast of the parent well with the laterals targeting the Kuparuk C sands. All laterals will be completed with 2-3/8" slotted liner from TD with the last lateral liner top located inside the 3-1/2" tubing tail.

Page 5 of 7 March 14, 2017 PTD Application: IC-23L1, 1C-23L1-01, 1C-23L1-02, 1C-23L1-03, 1C-23L1-04, & 1C-23L1-05 Pressure Deployment of BHA The planned bottom hole assemblies (BHAs) are too long to simply isolate by closing the double swab valves on the Christmas tree. MPD operations require the BHA to be lubricated under pressure using a system of double swab valves on the Christmas tree, double deployment rams, double check valves and double ball valves in the BHA, and a slick -line lubricator can be used. This pressure control equipment listed ensures there are always two barriers to reservoir pressure, both internal and external to the BHA, during the deployment process. During BHA deployment, the following steps are observed. — Initially the double swab valves on the tree are closed to isolate reservoir pressure. The lubricator is installed on the BOP riser with the BHA inside the lubricator. — Pressure is applied to the lubricator to equalize across the swab valves. The swab valves are opened and the BHA is lowered in place via slick -line. — When the BHA is spaced out properly, the double deployment rams are closed on the BHA to isolate reservoir pressure via the annulus. A closed set of double ball valves and double check valves isolate reservoir pressure internal to the BHA. Slips on the double deployment rams prevent the BHA from moving when differential pressure is applied. The lubricator is removed once pressure is bled off above the deployment rams. — The coiled tubing is made up to the BHA with the double ball valves plus the double check valves in the closed position. Pressure is applied to the coiled tubing to equalize internal pressure and then the double ball valves are opened. The injector head is made up to the riser, annular pressure is equalized, and the deployment rams are opened. The BHA and coiled tubing are now ready to run in the hole. During BHA undeployment, the steps listed above are observed, only in reverse. Liner Running — 1 C-23 CTD laterals will be displaced to an overbalance completion fluid (as detailed in Section 8 "Drilling Fluids Program") prior to running liner. — While running 2'/" slotted liner, a joint of 2%" non -slotted tubing will be standing by for emergency deployment. A floor valve is made up onto this joint ahead of time, and the rig crew conducts a deployment drill with this emergency joint on every slotted liner run. The 2%" rams will provide secondary well control while running 2%" liner. 14. Disposal of Drilling Mud and Cuttings (Requirements of 20 AA 25.005(c)(14)) • No annular injection on this well. • All solid waste will be transported to the grind and inject facility at DS-4 Prudhoe Bay for disposal. • Incidental fluids generated from drilling operations will be injected in a Kuparuk Class II disposal well (1 R-18 or I disposal facilities) or Prudhoe DS-4 if a Kuparuk facility is unavailable. • All wastes and waste fluids hauled from the pad must be properly documented and manifested. • Contact Kuparuk Environmental Coordinator for questions regarding waste classification.
