Well CD2-52 was drilled and completed in 2003 as an producer of the Apline reservoir. In 2018 a POGLM was installed over a flowcut GLM. In 2023 an attempt made made to pull the POGLM which was unsuccessful. Further attempts resulted in stuck SL fishing tools, and the POGLM slid downhole. Now a RWO is required to fish the POGLM and replace the tubing and GLMs. If you have any questions or require any further information, please contact me at 907-263-4529. The tubing will be cut and pulled above the current production packer. A new 3.5" completion, with a non sealing overshot and new packer, will be ran.

Attempt to fish POGLM-unsuccessful 2. Measure SBHP 3. Tag top of fish and located GLM #3 to determine top of fish relative to tally and GLM. Remaining Pre-Rig Work 1. Set RBP between top of fish at 12,159’MD and GLM at 12,089’. 2. Perform CMIT 3. Pull RBP 4. Cut tubing at ~12,150’ 5. Prepare well for rig arrival within 48-72 hours of rig arrival. Rig Work MIRU 1. MIRU Doyon 25 on CD2-52 2. Circulate KWF through pre rig tubing cut 3. Record shut-in pressures on the T & IA. If there is pressure, bleed off IA and/or tubing pressure and complete 30-minute NFT. Verify well is dead. Circulate additional KWF as needed. 4. Set BPV and confirm as barrier if needed, ND Tree, NU BOPE and test to 250/3,500 psi. Test annular 250/3,500 psi. Retrieve Tubing 5. Pull BPV, MU landing joint and BOLDS. 6. Pull 4-1/2” x 3-1/2” tubing down to pre rig cut (~12,150’). Recover Fish 6. RIH with burnover mill to burnover sliding sleeve at 12,176’ MD. 7. Millover sliding sleeve to reduce OD to allow for washover tubing cutters 8. RIH with washover exterior tubing cutters. Locate collar at estimated 12,220’ MD. Cut tubing and pull fish out to surface 9. RIH with dress off mill and casing string mills. Dress off tubing stub and clean casing around location of new stacked packer (~12,170 MD) 10. RIH with test packer. Set packer at planned packer location (~12,170’ MD). Test casing from packer to surface to 2500psi. Contingencies Due to the seasonal timing constraints of this project contingency options will be chosen based on success of sliding sleeve burn over operations and what remains in hole at that time. Contingency Option 1: Cut the tubing at the connection at 12,166’ (~est 7’ below top of fish). Then attempt to fish the SL fish and POGLM with DP conveyed fishing tools. Contingency Option 2: Run a non-sealing overshot over the pre-rig cut at ~12,150’ and run 4.5” tubing with a stacked packer set ~12,100’. This larger 4.5” tubing would allow for post-rig SL or CTU fishing with a higher chance of success than our current restrictions with 3.5” tubing. Contingency Option 3: CD2-52 RWO Procedure Alpine Producer Pull and Replace Tubing PTD #203-093 Page 2 of 3 Set a deep plug in the production casing above tubing stub and leave well shut in with a shallow kill string. This would require the rig to come back to attempt fishing operations again the following ice road season. If this option is pursued, we will submit a temporary suspend sundry. Install new 3-½” Tubing 11. MU 3 ½” completion with overshot, nipples, packer, GLM. 12. RIH with completion. Overshot tubing stub. 13. Space out as needed. Land tubing and RILDS. Test packoffs. 14.

The well is currently shut-in with a known TxIA issue awaiting intervention work to address the problem. The IA pressure is currently at 2200 psi. The production casing is 7” 26# L80 with a burst rating of 7240 psi. Our plan is to use coil to clean the wellbore out enough to access the POGLM patch in the well. At that point we will be able to troubleshoot the suspect POGLM and formulate a plan for a repair. This work can be performed in the near future and we believe the IA pressure is manageable until then. A 90-day TIO and well schematic are attached. Please let me know if you have any questions or disagree with the plan.

Overview: . C02-52: A hydraulic fracture treatment will be performed in the open hole horizontal section to establish communication vertically and longitudinally through the Alpine "C" sand. /This will increase the wells production rate and reserves. A coil clean out 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.

Some of these wells were found to have a void in the conductor by surface casing annulus. The voids that were greater than 3 feet were first filled with cement to a level of approx. 1.0 foot. The remaining volume of annular void respectively was coated with a corrosion inhibiter, RG2401 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 cement top-fill operation was completed on March 21st, 2007. Schlumberger Well Services mixed 15.7 ppg Arctic set I in a blender tub. The cement was pumped into the conductor bottom and cemented up via a hose run to the existing top of cement. The corrosion inhibitor sealant was pumped in a similar manner March 21 st_ 22n ,2007. The attached spreadsheet presents the well name, top of cement depth prior to filling, and volumes used on each conductor. Please call Jerry Dethlefs or MJ. Loveland at 907-659-7043, if you have any questions. Sincerely, CZ7~ ;:: Arend- ConocoPhillips Well Integrity Field Supervisor ~ ~~ äúANNEO MAR 2 B Z007 ., Attachment . . ConocoPhillips Alaska Inc.

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 C02-52. Well separation is 11.15 ft at 250 ft MO. Accounting for survey uncertainty, the ellipse-to-ellipse separation is 517 ft at 250 ft MD. Drillinq 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 Pumpinq Operations: Incidental fluids developed from drilling operations on well C02-52 will be injected into a permitted annulus on CD2 pad or the class 2 disposal well on CD1 pad. The C02-52 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 C02-52 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 300-400' 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 01 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 TVO) + 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 00 (ppf) Grade Range Type Collapse Collapse Burst Burst 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 ) ) CD2-52 DRILLING FLUID PROGRAM SPUD to Intermediate hole to 7" Production Hole 9-5/8"surface casing casing point - 8 Y2" Section - 6 1 18" point -12 ~" Density 8.8 - 9.6 ppg 9.6 - 9.8 ppg 9.1 ppg PV 1 0 - 25 15 -20 YP 20 - 60 15 - 25 18 -25 Funnel Viscosity 100 - 200 Initial Gels 4-8 NA 10 minute gels <18 9-12 API Filtrate NC - 10 cc I 30 min 4 -12 cc/30 min (drilling) NA HPHT Fluid Loss at 160 4.0-5.5 PH 8.5-9.0 9.0 -10.0 NA Electrical Stability +800Vts Oil Iwater ratio 80/20 Suñace Hole: A standard high viscosity fresh water I gel spud mud is recommended for the surface interval. Keep flowline 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 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 well bore 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. C02-52 PRESSURE INFORMATION AND CASING DESIGN (per 20 ACC 25.005 ( c ) (3,4) and as required in 20 ACC 25.035 (d) (2)) The following presents data used for calculation of anticipated surface pressure (ASP) during drilling of this well : Csg Setting Fracture Pore Casing Size Depth Gradient pressure ASP Drilling (in) MDfTVD(ft) (Ibs. I gal) (psi) (psi) 16 114/114 10.9 52 53 9-5/8 2677 / 2390 14.5 1081 1563 7 13065 I 7119 16.0 3221 2540 N/A 17064 I 7205 16.0 3260 N/A . NOTE: The Doyon 19 5000 psi BOP equipment is adequate. 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 0= 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] D == [(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] D = [(14.5 x 0.052) - 0.1] x 2390 = 1563 psi OR ASP = FPP - (0.1 x D) = 3221 - (0.1 x 7119') = 2509 psi 3. Drilling below intermediate casing (7") ASP == FPP - (0.1 x D) = 3260 - (0.1 x 7205') = 2540 psi ) ) Colville River Field CD2-52 Production Well Completion Plan Updated 5/20/2003 _....1 16" Conductor to 114' 3-%11 x 4-%11 cross-over, 2 jts below 4-%Dhanger 3-1/2" Cameo TRM-4E SSSV Nipple (2.813" ID) at 2000' TVD=2187' MD -2.813" X-Over -Single 1,4"xO.049" sls control line 9-5/8" 36 ppf J-55 STC Surface Casing @ 2677' MD I 2390' TVD cemented to surface :<~ÙJ Camco KBG-2 GLM (2.867· 10) at 3400' T,VO for E Dummy with 1· BK-2 Latch 3-1/2" 9.3 ppf L-80 18T Mod.
