Anchorage, Alaska 99501 Anchorage Dear Commissioner: ConocoPhillips Alaska, Inc. hereby submits an application for permits to drill two lateral sidetracks out of Kuparuk Weil 2Z-23 using the coiled tubing drilling rig, Nabors CDR2-AC. Work is scheduled to begin on 2Z-23 in later November 2010. The CTD objective is to drill two lateral sidetracks (2Z-23A and 2Z-23AL1); targeting the A3 and A4-sands to access reserves away from the parent wellbore, across isolating faults. The two laterals will be drilled from one, dual string casing exit through the selective interval (3.5"tubing x 7"casing). Attached to this application are the following documents: - Permit to Drill Application Forms for 2Z-23A and 2Z-23AL1 - Detailed Summary of Operations - Proposed Schematic - Directional Plans - Anti-collision Review - BOP Schematic If you have any questions or require additional information please contact me at 907-263-4093. Sincerely, Jill L g Coiled Tubing Drilling Engineer Permit to Drill Summary of Operations KRU 2Z-23 and 2Z-23AL1 Lateral Sidetracks Coiled Tubing Drilling Well History and Obiective Injecting well 2Z-23 was originally drilled and completed as in 1995 as a single, selective completion with both the A and C sands perforated. The 2Z-23 wellbore is in an area that contains many sealing and highly baffling faults, as well as a prolific C-sand. This faulting has caused a significant amount of compartmentalization in the A sands and has resulted in lower than expected oil recovery. The purpose of the CTD project is to drill two CTD lateral sidetracks in the A4 and A3 sands away from the parent . wellbore and across faults that are believed to be isolating. The sidetracks will be injecting laterals, the same as the parent wellbore. The outcome expected is improved sweep efficiency and oil recovery. Both the A and C sand perfortions in the parent wellbore are planned to be plugged using cement prior to CTD rig arrival. The lateral footage drilled in the immediate vicinity of parent well will recover the existing A sand perforations. A review of the C sand in the area confirmed that abandoning the C sand perforations in this parent wellbore should not have a significant impact on the rates of offset producers. Operational Outline Pre-Rig Work Remaining 1. Changeout all gas lift valves to dummy valves and caliper the 3.5"tubing across the selective interval. 2. Set a plug just above the bottom packer, isolating the A sand perforations. Pressure test the tubing to confirm integrity of the selective. 3. Punch holes —5' of holes below the sliding sleeve (to ensure cement in the annulus below the sliding sleeve). 4. Set EZSV cement retainer 5. Pump cement into the 3.5" x 7" annulus, squeezing off the A and C sand perforations and placing good cement in the annulus across from the CTD KOP 6. Perform a dummy whipstock drift. Set the lower whipstock at—7510' 7. Set BPV and prepare wellsite for rig arrival. . igoP re"s� P4A Rig Work General Plan 35o0105. 1. MIRU Nabors CDR2-AC rig using 2"coil tubing.

Page 1 of 3 MAL 10/21/2010 PTD Applications KRU 2Z-23A and 2Z-23AL1 Operational Details Hazards — Shale stability is a potential problem. Well 2Z-23 is in close proximity to 2Z-13 which encountered • significant shale problems while drilling. Managed pressure drilling (MPD) will be utilized on this well to minimize exposure problems. — Drillsite 2Z is an H2S pad. The maximum recorded H2S reading on the pad in 2010 was 135 ppm on well . 2Z-10 measured on 01/13/2010. Well 2Z-29 is the closest producing well to 2Z-23 (located —90' to the right on surface) and had an H2S reading of 50 ppm on 01/13/2010. All H2S monitoring equipment will be operational. Fluids Program — Chloride-based Biozan brine (8.6 ppg)will be used for window milling operations. • • — Chloride-based Flo-Pro mud (9.8 ppg)for drilling operations. — 2Z-23 does not contain a subsurface safety valve so completion kill weight fluid will be used for running completions. Disposal — No annular injection on this well. — Class II liquids to KRU 1R Pad Class II disposal well — Class II drill solids to Grind & Inject at PBU Drill site 4 — Class I wastes will go to Pad 3 for disposal.

No gyro will be run. - Distance to Nearest Property Line(measured to KPA boundary at closest point) Lateral Name Distance 2Z-23A 29800' • 2Z-23AL1 30400' - Distance to Nearest Well within Pool (toe measured to offset well) Lateral Name Distance Well 2Z-23A 1300' Toe measured r to 2X-15 • 2Z-23AL1 1250' Toe measured to 2X-15 Logging MWD directional, resistivity, and gamma ray will be run over the entire openhole section. • Reservoir Pressure The most recent static BHP survey in well 2Z-23 was taken August 2009. The reservoir pressure was measured at 2725 psi at 7567' MD/5840'TVDss, corresponding to 9.0 ppg EMW. • Well Control - Two well bore volumes (-190 bbl) of 12.0 ppg kill weight fluid will be within a short drive to the rig during drilling operations. In this situation, a"wellbore volume" is defined as the tubing volume plus the volume of the longest lateral. - BOP diagram is attached for operations with 2" coil tubing. - Pipe rams, blind rams and the CT pack off will be pressure tested to 250 psi and to 3500 psi. Maximum surface pressure anticipated while sidetracking out of 2Z-23 is -3000 psi, assuming a gas gradient to surface. This maximum potential surface pressure is calculated using the maximum expected reservoir pressure from 2Z-23 based on recent injection wellhead pressures at 2Z-23. (Recent wellhead pressure readings have been -950 psi which correlates to a bottomhole pressure at the kickoff point of -3500 psi. Assuming a gas gradient of 0.1 psi/ft, the maximum surface pressure expected would be -3000 psi.) - The annular preventer will be tested to 250 psi and 2500 psi. Managed Pressure Drilling Managed pressure drilling (MPD) techniques will be employed to provide constant bottomhole pressure by using - 9.8 ppg drilling fluid in combination with annular friction losses and applied surface pressure. Constant BHP will be utilized to reduce pressure fluctuations to help with hole stability. Applying annular friction and choke pressure also allows use of less expensive drilling fluid and minimizes fluid losses and/or fracturing at the end of the long well bores. A hydraulic choke for regulating surface pressure is installed between the BOPE choke D manifold and the mud pits, and is independent of the BOPE choke. Using this technique will require deployment of the BHA under trapped wellhead pressure. Pressure deployment of the 2%" BHA will be accomplished utilizing the 2%" pipe rams and slip rams. The annular preventer will act as a secondary containment during deployment and not as a stripper. The well will be loaded with overbalanced fluid prior to running completions. Operating parameters and fluid densities will be adjusted based on real-time bottom hole pressure measurements while drilling and shale behavior.

The distances noted are the closest proximity between these wellbores and any point along the planned CTD laterals. • - 2X-16 (active producer)-This wellbore is located -1245' to the southwest of laterals 2Z-23A and 2Z-23AL1. This well is a single completion with commingled production from perforations in both the A and C sands. - 2X-15 (active producer)-This wellbore is located -1285' to the northeast of laterals 2Z-23A and 2Z-23AL1.• This well is a selective completion with capability to produce from both the A and C sands. - 2Z-03 (shut-in injector) -This wellbore is located -1295' to the west of laterals 2Z-23A and 2Z-23AL1. This • well is a selective completion with capability to inject into both the A and C sands. The well is currently shut-in awaiting a flowline repair that will not likely occur until the year 2011.
