Please contact Stephanie Pilch or myself at 659-7126 if you have any questions. Sincerely, Sara Carlisle Well Integrity & Compliance Specialist ConocoPhillips Alaska, Inc. By Samantha Carlisle at 5:17 pm, Mar 27, 2020 P.O. BOX 100360 ANCHORAGE, ALASKA 99510-0360 CPAI Well Integrity & Compliance Specialist PROCEDURE FOR OUTER ANNULUS CEMENT SHOE CD4-304 (PTD 207-132) ConocoPhillips Alaska, Inc., (CPAI) intends to pump a cement shoe in the outer annulus (OA) of Alpine producer CRU CD4-304 (PTD 207-132). The OA in this well is the annular void between 7” casing and 9-5/8” casing. The annulus does not contain a cement shoe. CPAI is requesting to install a cement shoe to isolate the OA from shallow formation pressure. This isolation will allow the OA to be bled to 0 psi, which is required to progress the surface casing repair approved under Sundry #319-551. With approval, the OA cement shoe will require the following general steps: 1. Pump cement design to place ~1000 ft linear shoe in the OA. 2. Displace cement with freeze protection fluids. 3. Wait on cement to cure. 4. OA drawdown test. 5. Submit 10-404 to AOGCC.

AFE: 10419362 ZX12 DDD Sub PMO: 22971502 PMO 22971501 2. The surface casing mandrel hanger is a FMC Horizontal Type hanger and pup joint made of 4130 steel with 11-3/4" buttress threads. Surface casing is 9 5/8" 40# L-80 casing. Conductor is 16" 84# K-55 casing. 3. All tubular seals are rated to a maximum service temperature of 250 degrees F. 4. Well is a Gaslifted producer. The safe -out procedure includes setting a tbg plug to secure the well from the formation and ensuring that the tbg and IA are liquid packed with a diesel freeze protect cap. The well will be isolated from the facility by closed wing and lateral valves. Energy isolation lock -out & tag - out procedures apply. Well piping is to be removed from the wellhead area. A nitrogen purge will be maintained on the outer annulus (OA) during the welding operation with periodic monitoring of 02 and LEL levels. The conductor (OOA) will be tapped and purged as needed. The Tanko head needs to be removed, exercise extreme caution as there may be subsidence issues, causing growth of the well. 5. The wellhead area will need to be excavated to 9' to 24' and shoring box installed. Any contaminated cellar gravel will be removed. 6. On-site personnel should be limited to only those with activities and responsibilities associated with the job. 7. Any on-site personnel have the authority to stop or suspend the job should any safe -out or procedural conditions become suspect. Safety is everyone's responsibility. Job Preparation 1. Prepare In -Service package for welding. 2. Shut-in and secure well: Verify the IA fluid level is at surface and an MITIA passes. Freeze protect the tubing with diesel and set a tubing tail plug, pressure test plug and tubing. (Depending on IA FL and MITIA results, the tbg and IA may need to be displaced with seawater and a diesel cap to 2000' by circulating thru the bottom GLM.) 3. Bleed tubing, IA (3.5" x 7") and OA (7".x 9-5/8") to zero psi. Verify flow is zero; inability to maintain zero psi prior or during job will cancel the welding operation. 4. Remove wellhouse, floor kit, wellhead piping and platform. Remove wellhead jewelry and replace with alemites for excavation process. 5. Excavate to 11' to 26' backfill with 2' pea gravel. Set shoring and access point. (Stairs, scaffold work plat form and scaffold entry point from pad grade. 6. Connect indirect fired heater scaffold work platform for heat and ventilation. A second heater may be required for placing heat on the N2 manifold and break -shack (if needed). Station light plant on pad for increased visibility (if needed) during operation 7. Reinstall Wellhead jewelry and valve handles. 8. Pull VR plug and install opposing valve on casing head for N2 purge (NA). CD4 -304 Surface casing weld/repair NSK Well.

Checking areas of greatest loss. 11. Cut and remove conductor. Prep 9 5/8" 40# L-80 surface casing for leak detect. 12. Inspect for visible leak points, pressure test SC to identify leak point. 13. Kakivik to NDE testing of surface casing for "A" & "B" bands. 14. Weld shop fabs collars and sleeve per Field Mechanical Engineer specs. 15. Verify OA fluid level is at least 12" to 36" below weld point; remove fluid via suction hose as needed. 16. Install purge lines from N2 bottle rack to OA and from OA to slop trailer. Discharge will be monitored for LEL and 02 levels and must be accessible. Position slop trailer downwind and as far from excavation as is practical. 17. Install/weld collars. NDE testing of collars. `yp fz c/o CvrvrG 18. Install/Weld sleeve/ NDE testing of sleeve. 19. Pressure testing of repair. 20. Denso wrap entire SC. 21. Replace/weld 16" 84# K-55 conductor, from remaining conductor to bottom of the wellhead. 22. Remove hooch, scaffolding, and shoring box. 23. Backfill to within 4' of pad grade. 24. Install cellar box. Complete backfill operations. 25. Reinstall wellhead platform, piping, floor kit, and wellhouse. Job Procedure 1. Safety department will check entire well area before Hot Work commences. 2. Purge the OA with nitrogen, venting outside to slop trailer. Purged gas is to be monitored periodically throughout job for LEL and 02 levels. Target LEL at or below 10% and/or oxygen at or below 5%. The heating and cutting operation may commence after target LEL or 02 level is reached. 3. Establish fire watch and begin hot work, including prepping surface with torch, brushes, pre -heat with Cooper Machine, grinding or buffing as required. 4. Pre heat well heat with Cooper heat or heat machine per weld procedure. 5. Weld per PAI Welding Procedure determined by Facility Engineers specifying pre heat, welding and post heat requirements. 6.

The well was shut-in on March 251" for gas handling purposes during which the IA pressure rose to 2,355 psi. The well remains SI, and the IA pressure has been bled to 1,500 psi. The well has 7", 26 Ib/ft, L-80 grade production casing which has a burst pressure rating of 7,240 psi. We intend to trouble shoot the source of the high pressure as soon as we are logistically able. Our team is scheduled to begin diagnostics tomorrow. Once we determine the source of the high pressure, we will progress well work to restore the TxIA integrity as soon as possible.

Tom Maunder, PE AOGCC 5/6/2009 • Note to File CD4-05 (207-155...309-154) Colville River Unit (Alpine) ConocoPhillips Alaska, Inc Phillips has made application for annular disposal for the subject well. This document examines the pertinent information for the well and recommends denial of ConocoPhillips' request. While review of the submitted information indicated that CD4-05 was satisfactorily constructed and that disposal would likely occur at EMWs less than the initial surface shoe leakoff, exploration well Nanuq 3 (201-026) is only 222' distant. Nanuq 3's surface casing shoe is at about 1780' tvd in contrast to the nominal 2380' tvd depth of the other wells from CD-4. Several hundred feet of shallower production hole annulus is not cemented and if communication were established between the wellbores waste could move to shallower depths. There are documented cases where communication between wellbores has occurred with distances of about 300'. Based on examination of the submitted request for the subject well be denied.

Each of these wells was found to have a void in the conductor. These voids were filled with cement if needed and corrosion inhibitor, engineered to prevent water from entering the annular space. As per previous agreement with the AOGCC, this letter and spreadsheet serves as notification that the treatments took place and meets the requirements of form 10-404, Report of Sundry Operations.

Commission r~choraa ConocoPhillips Alaska, Inc. hereby applies for a Permit to Drill an onshore horizontal producer well from the Nanuq CD4 drilling pad. The intended spud date for this well is 10/20/2007. It is intended that Doyon Rig 19 be used to drill the well. CD4-304 is intended to be a horizontal Kuparuk C sand producer. However, the reservoir pressure may be too low and the sand may not be thick enough to drill a horizontal. Therefore a pilot hole, CD4- 304PB1, will be drilled through the Kuparuk sand at 70° to verify if a horizontal well is feasible. The pilot hole will be abandoned with 3 plugs. Then the well, CD4-304, will be kicked off at approximately 12,704' MD and landed in the Kuparuk C sand horizontally. `' After setting 7" intermediate casing the well will be completed as a slotted liner producer. The well will be flowed back to mitigate formation damage and then be closed in awaiting completion of well work for the well to begin production. CONTINGENCY PLAN: If the sand and pressures do not allow for a horizontal well, the intermediate casing will be run in the pilot hole. The well will be completed as a high angle slant and will be perforated before production. .~ It is expected that the K2 (Qannik) sand will be considered a significant hydrocarbon bearing zone. It is planned to pump lead cement, then open a stage tool and pump a second cement job to isolate the K2 with 500' of cement above and below the interval. This will leave a mud gap between the two stages. It is requested that a waiver of the diverter requirement under 20 AAC 25.035 (h)(2) be granted. There have been 19 surface holes drilled at CD4 and there has not been a significant show of shallow gas or gas hydrates. ---..

ORIGINAL Well Proximity Risks: Directional drilling /collision avoidance information as required by 20 ACC 25.050 (b) is provided in following attachments. CD4-306 is the nearest existing well to the CD4-304 plan with 16.7' well to well separation at 900' MD. Drilling Area Risks: There are no high-risk events (e.g. over-pressures zones) anticipated. ~' Lost circulation: Faulting and low reservoir pressure within the Kuparuk reservoir section is considered to be the most likely cause of lost circulation. Standard LCM material and well bore strengthening pills are expected to be effective in dealing with lost circulation. If GeoTap measurements indicate pressures are too low to drill the horizontal the well will be completed as a high angle slant. Additional care and attention will be given to the higher potential of inducing a kick when drilling horizontally as opposed to vertically. Good drilling practices will be stressed to minimize the potential of taking swabbed kicks. Annular Pumping Operations: Incidental fluids developed from drilling operations on well CD4-304 will be injected into a permitted annulus ~ on CD4 pad or the class 2 disposal well on CD1 pad. The CD4-304 surface/intermediate casing annulus will be flushed with 300 bbls of fresh water prior to freeze protecting with diesel to 2000' TVD. The significant hydrocarbon zones are the Nanuq, Kuparuk, and the Qannik reservoir. There will be 500' of cement fill above the top of the Nanuq and Qannik reservoirs. Upon completion of CD4-304 form 10-403, Application for Sundry Operations, will be filed. Annular pumping of fluids occurring due to drilling operations, per regulation 20 AAC 25.080, could then begin once properly permitted. As stated above, any zones containing significant hydrocarbons will be isolated prior to initiating annular pumping. There will be no USDW's open below the shoe or potable/industrial water wells within one mile of the receiving zone. Reference the enclosed directional drilling plan for other formation markers in this well. Surface casing will be set near the base of the Schrader Bluff Formation (C-40). These 450-500' thick shales are part of the Colville Group and are known to provide vertical barriers to fluid flow in other areas. The maximum volume of fluids to be pumped down the annulus of this well will not exceed 35,000 bbl without the specific permission of the AOGCC. Fluid densities will range from diesel to a maximum of 12.0 ppg for drilling fluid wastes. Using 12.0 ppg fluid and the rig's specified maximum pumping pressure of 1,500 psi for annular injection, the maximum pressure at the surface casing shoe is estimated by: Max Shoe Pressure = (12.0 ppg) * (0.052) " (Surf. Shoe TVD) + 1,500 psi _ (12.0 ppg) * (0.052) " (2400') + 1,500 psi = 2998 psi Pore Pressure = 1,086 psi Therefore Differential = 2998 - 1086 = 1912 psi. The internal casing pressure is conservative, since frictional losses while pumping have not been taken into consideration. The surface and intermediate casing strings exposed to the annular pumping operations have sufficient strength by using the 85% collapse and burst ratings listed in the following table: OD Wt (ppf) Grade Range Connection Type Collapse 85% of Collapse Burst 85% of Burst 9-5/8" 40 L-80 3 BTC 9,090 psi 1,717 psi 5,750 psi 2,992 psi 7" 26 L-80 3 BTC-Mod 5,410 psi 4,599 psi 7,240 psi 6,154 psi ORIGINAL DRILLING FLUID PROGRAM SPUD to 9-5/8"surface casing oint - 12 %' Intermediate hole to 7" casing point-8'/<" Production Hole Section - 6 1/8" Density 8.8 - 9.6 PP9 9.6 - 9.8 ppg 8.1-8.8 ppg ~' PV 10 - 25 10 -15 YP 20 - 60 15 - 25 25 -30 Funnel Viscosity 100 - 200 Initial Gels 4 - 8 10-15 10 minute gels <18 12-20 API Filtrate NC - 10 cc / 30 min 4 - 12 cc/30 min NA HPHT Fluid Loss at 160 (drilling) 12-14 cc/30 min PH 8.5-9.0 9.0-9.5 KCL 9.0 - 10.0 6% Surface Hole: A standard high viscosity fresh water /gel spud mud is recommended for the surface interval. Keep flow line viscosity at ± 200 sec/qt while drilling and running casing. Reduce viscosity prior to cementing. Maintain mud weight < 9.6 ppg by use of solids control system and dilution where necessary. Intermediate Hole Section: Fresh water gel /polymer mud system. Ensure good hole cleaning by pumping regular sweeps and maximizing fluid annular velocity. There is potential for lost circulation, particularly after the reservoir is penetrated. Maintain mud weight at or below 9.8 ppg and be prepared to add loss circulation material. Good filter cake quality, hole cleaning and maintenance of low drill solids (by diluting as required) will all be important in maintaining wellbore stability. Production Hole Section The horizontal production interval will be drilled with a M-I Flo-Pro drill-in fluid. The base fluid will consist of 6% KCI, with ± 30PPB calcium carbonate bridging material to minimize formation damage. Flo-Vis Polymer and Dual-Flo starch will be used for viscosity and fluid loss control respectively.
