CRU CD2-58 (PTD 203-085) for OA cementing. The goal of the cementing is to mitigate the pressure source and potentially repair the surface casing leak. Please contact me at (907) 263-3782 if you have any questions. Sincerely, Mark Shulman WNS Well Integrity Engineer ConocoPhillips Alaska Inc. Mark.Shulman@conocophillips.com Mark Shulman Digitally signed by Mark Shulman Date: 2025.07.16 16:22:14 -08'00' CD2-469 Cement Shoe Page 1 Date: July 16, 2025 Subject: CD2-58 OA Cement Shoe Procedure: Network #: Prepared By: Mark Shulman, 263-3782 Objective Down squeeze 9-5/8”x 7” OA to cement surface casing shoe to surface. Cement Volume Calculations: x Volume in 9-5/8”x 7” annulus: (3,056 ft; 2,390’ TVD) x (0.0297bbl/ft) = 88 bbl x Total volume: 153 bbls mixed (11 and 15.8 ppg) + 100 bbls (dry 15.7 ppg) = 253 bbl Backup KWF: 12.5 ppg: 100 bbls (OA with KWF is static head of 1,550 psi) CRU CD2-58 (PTD# 203-085) is a producer that was originally drilled and completed in 2003. The well is currently shut-in for a surface casing leak and rock production. CD2-58 needs a surface casing repair. CD2-58’s OA maintains a pressure of +400 psi. Surface casing LOT was 16 ppg when drilled in 11/2008. The goal of the OA cementing is to control the OA pressure by pumping an OA cement shoe to surface. Procedure 1. Verify 10-403 Sundry form has been approved for OA cement job. 2. Contact Cement Pumping Services to schedule the OA cement job and allow time for pilot testing. 3. Conduct Safety Meeting and Identify Hazards. Inspect wellhead and pad condition to identify any pre-existing conditions. 4. Install 1502 union and valves on the OA. Rig up hardline to the OA with an option to divert to open top tank for wash up. (see setup picture #1 below) 5. Ensure Valve crew services OA valves and any additional hardline valves installed for cementing job. 6. Install containment into cellar to contain any returns from surface casing leak. Ensure vac truck on location with cement containment to take returns from surface casing leak from pumping operations. 7. MIRU cement pumping equipment and rig up 2” hardline to the circulation skid. Stage equipment to minimize pumping stop time between stages. 8. Be sure to monitor around wellhead, wellhouse, and conductor top during OA pumping. There is a known surface casing leaks near the surface. During the OA injectivity testing returns were observed at the conductor. CD2-469 Cement Shoe Page 2 9. PT lines and surface equipment to 3,000 psi. 10. Pumping the OA shoe recommendations: a. Complete an Injectivity test up to 1500 psi. and ensure that OA will take injection. i. Lead with methanol and swap to diesel for injection test. b. At the beginning of the job, increase the pump pressure as necessary to break over on injection. i. Do not exceed 1,000 psi. c. Once the OA breaks over pump at maximum possible rate without exceeding maximum pressure of 1,000 psi. d. When cement gets to the shoe (88 bbls pump total after starting on cement), slow pumps to a maximum of 1 BPM or 500 psi. e. With 25 bbls of cement past the shoe (113 bbls after starting cement), shut- down pumps and watch pressure. f. Perform a 15-minute hesitation, then attempt to slowly squeeze another 10 bbls at minimum rate. g. Continue 15-minute hesitation steps with 10 bbls at minimum rates until well locks-up. i. If OA does not catch pressure after 123 bbls are pumped in OA, stop pumping cement and swap to pump 100 bbls of 12.5 ppg KWF in OA to FP and keep the shoe open and contact Wells Supervisor, production engineer and WI engineer. h. Use cement composition (11 # and 15.7 #) on page #4-5. 11. Pump Schedule: a. Complete injectivity test with methanol and swap to diesel. b. 10 bbls hot diesel per Wells Supv. c. 65 bbls 90oF hot freshwater for flush of the OA. d. 20 bbls CW100 surfactant wash. e. 10 bbls freshwater spacer. f. 15 bbls 15.8# Class G cement (neat). g. 98 bbls 11# Class G cement with 2 lbs/bbl of CemNet/Artic slurry gas blocker. i. Perform 15-minute hesitation. h. 10 bbls of 15.8# Class G cement with 2 lbs/bbl of CemNet/Artic slurry gas blocker. i. Repeat 15-minute hesitation step i. 10 bbls of 15.8# Class G cement with 2 lbs/bbl of CemNet/Artic slurry gas blocker. i. Repeat 15-minute hesitation step j. 10 bbls of 15.8# Class G cement with 2 lbs/bbl of CemNet and gas blocker. i. Repeat 15-minute hesitation step k. If well locks up while pumping cement, go to next step. CD2-469 Cement Shoe Page 3 12. Close annulus, open the cement clean up line, and circulate to tanks to wash up tree and surface equipment. Top off OA with diesel for freeze protection. 13. Do not bleed the OA. Monitor the conductor top and downspout and vac out fluids if needed. 14. Wash up cementing equipment, RDMO. 15. Send OA cement shoe field blend UCA results to mark.shulman@conocophillips.com 16. After the cement cures for 72 hours, perform OA drawdown test. 17. If DDT passes DHD to drop string line and verify top of cement. 18. Report well work to AOGCC on 10-404 form.

ALPINE WELL CD2-58 (PTD 203-085) SUNDRY NOTICE 10-403 APPROVAL REQUEST November 6, 2023 This application for Sundry approval for Alpine well CD2-58 is for the inspection and repair of surface casing with a suspected surface casing leak. Subsequent diagnostics indicate that the leak is relatively shallow. ConocoPhillips requests approval to inspect and repair the surface casing. With approval, inspection and repair of the surface casing will require the following general steps: 1. Secure the well as needed with mechanical plug in the tubing. 2. Remove the floor grate, well house, flow lines, and other equipment as necessary from around the wellhead. 3. Remove gravel around well head and excavate well. 4. Install nitrogen purge equipment for the conductor and OA (if needed) so that hot work may be conducted in a safe manner. 5. Cut windows in the conductor casing and remove cement from the outside of the surface casing for inspection. Remove additional conductor as necessary. Notify AOGCC Inspector for opportunity to inspect. 6. CPAI Mechanical Engineers will determine type of patch or repair needed to return the casing to operational integrity. 7. QA/QC will verify the repair for a final integrity check. 8. Perform a pressure test to confirm no fluid to surface. 9. Install anti-corrosion coating as specified by CPAI Corrosion Engineer. 10. Replace the conductor and fill the void with cement and top off with sealant. 11. Backfill as needed with gravel around the wellhead. 12. Remove plug(s) and return the well to production. 13. File 10-404 with the AOGCC post repair.

Each of these wells was found to have a void in the conductor. These voids were filled with cement 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. The corrosion inhibitor /sealant was pumped March 13 -15 and March 27 -28, 2011. The attached spreadsheet presents the well name, top of cement depth prior to filling, and volumes used on each conductor.

This will increase the wells production rate and reserves. A coil cleanout will only be performed should it be necessary post-frac. Procedure: 1. MIRU seven clean insulated frac tanks with a berm surrounding the tanks that holds the tank volume plus 10%. Load tanks with seawater from the injection system (approximately 2500 bbls are required for the treatment) ,_. ,. .. .. 2. Rig up Dowell equipment and stab Tree Saver. (Test tree saver seals to expected pressure using warm diesel to assure seal integrity in tubing hanger). 3. Pressure test surface lines to 9500 psi 4. Pump the 100 bbl Breakdown with Dowell's YF125ST fluid system. Bring pumps up to maximum rate ASAP. 5. Pump the following schedule at 30 BPM with a maximum pressure of 9000 psi, add breaker as per lab results. Maintain 3000 psi on the IA during the treatment. · 300 bbls YF125ST Pad · 240 bbls YF125ST w/2 ppa 16/30 White Sand · 480 bbls YF125ST w/4 ppa 16/30 White Sand · 1000 bbls YF125ST w/7 ppa 16/30 White Sand · Flush with linear YF125ST and freeze protect Total Sand: -310,OOOlbs. 6. Monitor the surface pressure fall-off at the end of the job for 30 min (or until closure is verified) if the well does not screen out. 7. Rig down equipment, (and prep for next well frac after evaluation by Engineering) move off location. FCC if required with slick diesel.

Closer look at CDl-21 shows first horizontal was out the bottom of sand from 10,680 - 11,620' and then went out the top at 11,740' md. With sidetrack point at 9910', there is approx 700' of sand in abandoned hole that could take fluid (assuming that was reason for L1 designation, see attached email from 2/26/01 on API suffix numbering) .

Did review the logs with geologist and found, unfortunately that the sidetracks were due to going out the top of sand. Pulled back to where horizontal was in sand and then resumed drilling ahead. So don't expect any contribution to production from the abandoned holes. The CD2-15 3rd leg start point of 13,410' is correct, but the end of 2nd leg should be 13,776' (not 13,376' as shown on drawing). Sharon is compiling the ASP coordinates and tvd's and will send those over.

You mentioned that there are some other wells where you have also done OH sidetracks at Alpine. Could you give us a list of these wells and the "numerology" specifics.

CDl-21 on CD1 pad also had an open hole sidetrack. I am checking to be sure how the naming was handled, but I think on all of these wells we followed the same convention, ie PB1 and -7x API suffix for the inaccessible hole. See the attached schematic with the depth details. Let me know if you have any questions. (See attached file: Visio-Sidetracks.pdf) Thanks Tom, Vernon T Johnson wrote: I will pass this on to Steve Davies and we will have a look. Tom Maunder Vern, Thanks for the information. Could you please provide a little information as to why the OH sidetracks were performed?? Was it a case of rock quality or (gasp) going out of the top of the reservoir?? At first glance the "non accessible" wellbore sections are much shorter than on CD2-58, although that is not the case on CDl-21. You might also look at the "take off" point of the 3rd leg of CD2-15. Should that md be 13140?? Also, was/is there an expectation that the "non accessible" legs will contribute to the wells production?? Could you also provide the ASP coordinates and TVDs of the various take off points and TDs??

It is likely, as you hope, that this wellbore section will contribute to total production. If you can get the paperwork in tomorrow, we would appreciate. Since this is an ongoing operation, we will not hold you up, but the paperwork should be in a promptly as possible.

'07 ~,C( ( Well Proximity Risks: Directional drilling / collision avoidance information as required by 20 ACC 25.050 (b) is provided in following attachments. C02-51 will be the closest well to C02-58. Well separation is 71.41 ft at 275 ft MD. Accounting for survey uncertainty, the ellipse-to-ellipse separation is 5.1 ft at 275 ft MD. Drillina Area Risks: There are no high-risk events (e.g. over-pressures zones) anticipated. Lost circulation: Faulting within the Alpine reservoir section is considered the most likely cause of lost circulation. Standard LCM material has proved effective in dealing with lost circulation in previous development wells. 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 Pumpina Operations: Incidental fluids developed from drilling operations on well CD2-58 will be injected into a permitted annulus on C02 pad or the class 2 disposal well on CD1 pad. The CD2-58 surface/intermediate casing annulus will be flushed with 300 bbls of fresh water prior to freeze protecting with diesel to 2000' TVD. The only significant hydrocarbon zone is the Alpine reservoir and there will be 500' of cement fill above the top of the Alpine as per regulations. We request that CD2-58 be permitted for annular pumping of fluids occurring as a result of drilling operations, per regulation 20 AAC 25.080. 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 below the base of the Schrader Bluff Formation (C-40). These 300-4001 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) * (2390') + 1,500 psi = 2,990 psi Pore Pressure = 1,081 psi Therefore Differential = 2991 - 1081 = 1910 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: Wt Connection 85% of 85% of OD (ppf) Grade Range Type Collapse Collapse Bu rst Bu rst 9-5/8" 36 J-55 3 BTC 2,020 psi 1,717 psi 3,520 psi 2.992 psi 7" 26 L-80 3 BTC-Mod 5,410 psi 4.599 psi 7,240 psi 6,154 psi ¡""'R~ 'i Il~ .~ ,1 ;;':1 ~v ' ,~ ~ JlliJ #1 ' )¡ a ,!

Keep flowline viscosity at ± 200 seb/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 I 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 Alpine 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 80/20 oil/water ratio M-I Versa-Pro mineral oil based drill-in fluid. The base fluid will consist of high flashpoint (>200 F) mineral oil with 25% by weight calcium chloride as the internal phase. Calcium carbonate bridging material will be added to minimize formation damage. J ~~ I~ ,!;f-ì f¡'!'J A I ~~ , ': ~q'i ,,"'~ r I.

Test BOP's to 5000 psi. PROCEDURE FOR CALCULATING ANTICPATED SURFACE PRESSURE (ASP) ASP is determined as the lesser of 1) surface pressure at breakdown of the formation casing seat with a gas gradient to the surface, or 2) formation pore pressure at the next casing point less a gas gradient to the surface as follows: 1) ASP = [(FG x 0.052) - 0.1]0 Where: ASP = Anticipated Surface pressure in psi FG = Fracture gradient at the casing seat in Ib/gal 0.052 = Conversion from Ib./gal to psi/ft 0.1 = Gas gradient in psi/ft D = true Vertical depth of casing seat in ft RKB OR 2) ASP = FPP - (0.1 x D) Where; FPP = Formation Pore Pressure at the next casing point ASP CALCULATIONS 1. Drilling below conductor casing (16") ASP = [(FG x 0.052) - 0.1] 0 = [(10.9 x 0.052) - 0.1] x 114 = 53 psi OR ASP = FPP - (0.1 x D) = 1081 - (0.1 x 2390') = 842 psi 2. Drilling below surface casing (9 5/8") ASP = [(FG x 0.052) - 0.1] 0 = [(14.5 x 0.052) - 0.1] x 2390 = 1563 psi OR ASP = FPP - (0.1 x D) = 3270 - (0.1 x 7227') = 2547 psi 3.

Depositionaly, wells along the southern row of C02 are targeting the distal margin of the shoreface deposits developed in the core of C02. Intermediate shale beds develop in the sands to the south and net/gross ratios begin to drop. C02-58 is planned to land in the upper part of the Alpine C to capture the good quality sand that was seen in the heel portion of CD2-36. We'll attempt to stay in this as long as we can then begin to drop as the upper sands begin to shale out. A mid-point target is given in addition to the heel and toe targets. Further adjustment may be made to the targets depending on where the top Alpine C comes in prior to landing or based upon sand quality. No faults have been mapped along the wellbore, but three areas have been identified as possible small faults at or near our seismic resolution. These are - 13,800' md possible small down to north fault (-10ft), -14,300' md possible small down to north fault (-10ft), and -15,200' md possible small down to the north south fault (-10ft). These areas should be noted as possible areas of lost circulation while drilling. t~¡.. ~r ~1 ,i ' "';\'.'/' , I)J A L ::,"""1'>0, , ConocoPhillips Alaska, Inc.

CcmmiMn Anchorage', Dear Sir or Madam: ConocoPhillips Alaska, Inc. hereby applies for a Permit to Drill an onshore production well from the Alpine CD2 drilling pad. The intended spud date for this well is May 21, 2003. It is intended that Doyon Rig 19 drill the well. The well CD2-58 will be drilled to penetrate the Alpine sand horizontally. 7" casing will then be run and cemented in place. The 6-1/8" horizontal section will be drilled with oil based mud using mineral oil as the base fluid. CD2-58 will be completed as an open hole producer. At the end of the work program the well will be shut in awaiting surface connection. Note that it is planned to drill the surface hole without a diverter. There have been 38 wells drilled on CD1 pad and 32 wells drilled on CD2 pad with no significant indication of gas or shallow gas hydrates. It is also requested that the packer placement requirement be relaxed to place the completion packer 200 ft TVD above the Alpine formation. This will place the completion at maximum inclination of less than 65 degrees and allow access to the completion with standard wireline tools for future intervention. Please find attached the information required by 20 ACC 25.005 (a) and (c) for your review. Pertinent information attached to this application includes the following: 1. Form 1 0-401 APPLICATION FOR Permit to Drill per 20 ACC 25.005 (a). 2. Fee of $100 payable to the State of Alaska per 20 ACC 25.005 (c) (1). 3. A proposed drilling program, including a request for approval of annular pumping operations. 4. A drilling fluids program summary. 5. Proposed completion diagram. 6. Proposed completion diagram with open hole isolation options. 7. Pressure information as required by 20 ACC 25.035 (d)(2). 8. Directional drilling / collision avoidance information as required by 20 ACC 25.050 (b). Information pertinent to this application that is presently on file at the AOGCC is: 1. Diagrams of the BOP equipment, diverter equipment and choke manifold layout as required by 20 ACC 25.035 (a) and (b). 2. A description of the drilling fluids handling system. 3. Diagram of riser setup which replaces diverter. OR:G~NAl ) ) If you have any questions or require further information, please contact Zane Kuenzler at 265-1308 or Chip Alvord at 265-6120.
