CDR3-AC previously attempted to drill the 1 R-231-1 (219-128) lateral in October 2019, but after drilling 3 plugbacks due to hole cleaning and hole stability issues, the decision was made to RDMO. The well is currently being set-up for a cement pilot hole exit by cement squeezing the original C-sand perforations up to the tubing tail. CDR3-AC plans to return to the well and CTD operations are scheduled to begin on December 5th, 2019. The objective will be to drill three laterals — 1 R-23A and 1 R-23AL1 will be unlined delineation laterals to the north and east, crosscutting through the A3 and C1 sands. 1 R-23AL2 will be drilled to the north targeting the C1 sands and lined with 2-3/8" solid and slotted liner from TD up into the tubing tail. The fourth lateral, 1 R-_ 23AL3, will be a contingency lateral that will target the C1 sands in an upthrown fault -block. This lateral will be drilled only if the oil -water -contact comes in higher than anticipated and the project does not get completed to scope. To account for geological uncertainties, ConocoPhillips requests a variance from the requirements of 20 AAC 25.015 to allow the actual kick-off point to be anywhere along the length of the parent lateral instead of being limited to 500' from the original point. Attached to this application are the following documents - Permit to Drill Application Forms (10-401) for 1 R-23A, 1 R-23AL1, & 1 R-23AL2, & 1 R-23AL3 - Detailed Summary of Operations - Directional Plans for 1 R-23A, 1 R-23AL1, & 1 R-23AL2, & 1 R-23AL3 - Current wellbore schematic - Proposed CTD schematic If you have any questions or require additional information, please contact me at 907-265-6218.

Well Name and Classification (Requirements of 20 AAC 25.005(f) and 20 AAC 25.005(b)) The proposed laterals described in this document are 1 R-23A, 1 R-23AL1, & 1 R-23AL2 & 1 R-23AL3. The laterals will be classified as "Development - Oil" wells. 2. Location Summary (Requirements of 20 AAC 25.005(c)(2)) These laterals will target the C1 and A3 sand packages in the Kuparuk reservoir. See attached 10-401 form for surface and subsurface coordinates of 1 R-23A, 1 R-23AL1, & 1 R-23AL2 & 1 R-23AL3. . 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 3517 psi in 1 R-23 (i.e. 10.0 ppg EMW), the maximum potential surface pressure in 1 R-23, assuming a gas gradient of 0.1 psi/ft, would be 2841 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 R-23 was measured to be 3517 psi (10.0 ppg EMW) on 12/20/2010. The maximum downhole pressure in the 1 R-23 vicinity is the 1 R-23 at 3517 psi or 10.0 ppg EMW on 12/20/2010. 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 1 R-23A laterals. If 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 R-23A laterals will be shale instability across faults. Managed pressure drilling (MPD) will be used to reduce the risk of shale instability associated with fault crossings. 5. Procedure for Conducting Formation Integrity tests (Requirements of 20 AAC 25.005(c)(5)) The 1 R-23A, 1 R-23AL1, & 1 R-23AL2 & 1 R-23AL3 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 PowerVis mud (8.6 ppg). This mud weight may 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 a weighted 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 5,000-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". Page 3 of 7 September 16, 2019 PTD Application: 1 R-23A, 1 R-23AL1, & 1 R-23AL2 & 1 R-23AL3 In the 1 R-23A laterals we will target a constant BHP of 11.8 EMW at the window. 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.

Proposed Drilling Program (Requirements of 20 AAC 25.005(c)(13)) Summary of Operations Background In October 2019, CDR3-AC rigged up and attempted to drill 3 laterals out of KRU 1 R-23. After 3 plugbacks while drilling the 1 R-231_1 lateral, due to poor hole conditions and hole cleaning issues, the decision was made to RDMO and reattempt at a later date via cement pilot hole exit. This will require E-line to perforate the tubing tail, and service coil to cement squeeze the C-sand perforations up to the tubing tail. This wellwork is ongoing. CDR3-AC will return to 1 R-23 in mid -December, mill a pilot hole down to 11,680' MD, set a whipstock and mill a 2.80" window in the production casing at a depth of 11,650' MD. After that, the 1 R-23A delineation lateral will be drilled to the north and crosscut through the C1 and A3 sands to determine rock quality and oil -water contact in both sand packages. An anchored billet will be set and the 1 R-23AL1 lateral will be drilled to the east, crosscutting through the C1 and A3 sands to determine rock quality and OWC in the eastern fault block. Finally, an anchored billet will be set and the 1 R-23AL2 lateral will be drilled to the north, targeting the C1 sands, and lined with 2-3/8" slotted liner to the tubing tail. If the C1 sands are found to be wet due to a higher than anticipated oil -water -contact, the1 R-23AL2 lateral will not be drilled and instead a contingency lateral 1 R-23AL3 will be Page 4 of 7 September 16, 2019 PTD Application: 1 R-23A, 1 R-23AL1, & 1 R-23AL2 & 1 R-23AL3 drilled targeting the C1 sands in an upthrown block This lateral will be lined with 2-3/8" slotted liner from TD to the tubing tail.

Pressure Deployment of BHA The planned bottom hole assemblies (BHAs) are too long to simply isolate by closing the swab valve on the Christmas tree. MPD operations require the BHA to be lubricated under pressure using the swab valve on the Christmas tree, deployment ram on the BOP, check valve and ball valve in the BHA, and a slick -line lubricator. This pressure control equipment listed ensures reservoir pressure is contained during the deployment process. During BHA deployment, the following steps are observed. — Initially the swab valve on the tree is 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 valve. The swab valve is opened and the BHA is lowered in place via slick -line. — When the BHA is spaced out properly, the deployment ram is closed on the BHA to isolate reservoir pressure via the annulus. A closed ball valve and check valve isolate reservoir pressure internal to the Page 5 of 7 September 16, 2019 PTD Application: 1 R-23A, 1 R-23AL1, & 1 R-23AL2 & 1 R-23AL3 BHA. Slips on the deployment ram prevent the BHA from moving when differential pressure is applied. The lubricator is removed once pressure is bled off above the deployment ram. — The coiled tubing is made up to the BHA with the ball valve in the closed position. Pressure is applied to the coiled tubing to equalize internal pressure and then the ball valve is opened. The injector head is made up to the riser, annular pressure is equalized, and the deployment ram is 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 — The 1 R-23A, 1 R-23AL1, & 1 R-23AL2 & 1 R-23AL3 laterals will be displaced to an overbalancing fluid prior to running liner. See "Drilling Fluids" section for more details. — While running 2-3/8" slotted liner, a joint of 2-3/8" 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 2-3/8" rams will provide secondary well control while running 2-3/8" liner 14. Disposal of Drilling Mud and Cuttings (Requirements of 20 AAC 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 1 B 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.

The paperwork has just increased. This is what is needed: 1. A plug for redrill sundry for KRU 1R-23(PTD 191-101); we can change this existing sundry(319-492) to plug for redrill by hand. No need to resubmit the whipstock sundry. 2. However, the naming convention of the sidetrack and laterals must change as follows and new PTDs must be submitted: a. Well KRU 111-231-1 will need to be resubmitted as KRU 1R-23A b. Well KRU 1R-231-1-01 will need to be resubmitted as KRU 1R-23A-01 c. Well KRU 1R-23L1-02 will need to be resubmitted as KRU 1R-23A-02 d. These will all be assigned new PTD and API numbers. The motherbore will be abandoned and the KRU 1R-23L1 closed out. I will route the plug for redrill whipstock for KRU 111-23 for approval today or Monday. However, please submit the required new PTDs. So sorry for the additional paperwork. Let me know if any clarification is needed.

After 3 unsuccessful attempts at drilling the 111-231-1 lateral, primarily due to hole cleaning issues in the 7 production casing, the decision was made to rig down CDR3-AC from 111-23 and set the well up for a cement pilot hole exit for the rig to come back at a later date and complete the scope of the project under the approved PTD. In preparation for resuming CTD operations on this well, perforations will be shot in the tubing tail, cement will be pumped to occupy the 7" casing and plug off C-sand perforations, and the XN nipple in the tubing tail will be milled out. CDR3-AC will mill a cement pilot hole, set a 3-1/2" whipstock, and mill a 2.80" window in the production casing at a depth of 11,662' MD and complete the original scope of the project under the existing permits. We are requesting verbal approval for an Operations Shutdown with the Sundry to be submitted today. We will also submit a subsequent sundry request for cement -squeezing the C-sand perforations and setting a new whipstock prior to beginning the service coil work.

Guy attached are conditions of approval that I'm attaching to DS-3R producers relating to the no flow test required for elimination of the SSSV requirement. I worked on these conditions with Jim and would like to be consistent with the DS-3R producers. CTD PTDs that will be submitted include KRU 1R-23 sidetrack and laterals and 3H-01 sidetrack and laterals: Mel will handle these; Mel, I attached 10-401 "condition" for kickoff point variance so you can see what we have been granting on these CTD laterals. Note, originally the 111-23 PTDs were approved as laterals because C sand was left open in the motherbore. This has changed. They are now plugging the motherbore and drilling a sidetrack (111-23A) plus laterals. The plug for redrill sundry for the motherbore has been approved however they will be submitting new PTDs(10-401s) for the 1R-23 sidetrack and laterals. Also attached is 10-401 Conditions of Approval for running the sonic for cement evaluation for wells to be fracked or injectors which I have been including as a part of the 10-401 approval.
