SECTION 2 – PLAT 20 AAC 25.283 (2)(A) Plat 1: Wells within 1/2 mile Table 1: Wells within 1/2 miles (2)(C) SECTION 3 – FRESHWATER AQUIFERS 20 AAC 25.283(a)(3) There are no known underground sources of drinking water within one-half mile radius of the current or proposed wellbore trajectory. Well 3T-622 lies within acreage that was located inside the former Oooguruk Unit before it was purchased by ConocoPhillips Alaska Inc. and included within the 12th expansion of the KRU. Page 17 of EPA class I UIC permit number AK1I009-B for Oooguruk Unit disposal wells DW-1 and DW-2 (obtained with that purchase) states: “The requirement to monitor the strata overlying the confining zone for fluid movement is waived since the aquifers at the Oooguruk Unit are too naturally saline to qualify as USDWs (meet “No USDW” criteria).” SECTION 4 – PLAN FOR BASELINE WATER SAMPLING FOR WATER WELLS 20 AAC 25.283(a)(4) There are no water wells located within one-half mile of the current or proposed wellbore trajectory and fracturing interval. A water well sampling plan is not applicable. SECTION 5 – DETAILED CEMENTING AND CASING INFORMATION 20 AAC 25.283(a)(5) All casing is cemented and tested in accordance with 20 AAC 25.030. See Wellbore schematic for casing details. SECTION 6 – ASSESSMENT OF EACH CASING AND CEMENTING OPERATION TO BE PERFORMED TO CONSTRUCT OR REPAIR THE WELL 20 AAC 25.283(a)(6) Casing & Cement Assessments: The 10-3/4” casing cement report on 09/15/2025 shows that the job was pumped with 401 barrels of 11.0 ppg lead cement and 60.3 barrels 15.8 ppg tail cement. This was displaced with 225 bbl 9.8 ppg spud mud. The plug bumped and the floats held. The 7-5/8” casing cement report on 09/22/2025 shows that the job was pumped as designed, indicating competent cementing operations. The cement job was pumped with 143 barrels of 14.0 ppg lead cement, followed with 67.8 barrels of 15.3 ppg tail cement. This was displaced with 431.5 barrels of 9.0 ppg NAF. The plug bumped, pressure was bled off, and floats were confirmed to be holding. A cement bond log indicates competent cement with a cement top @ 4,485’ MD (3,240’ TVD). The 4-1/2” liner cement report on 10/07/2025 shows the job was pumped as designed, indicating competent cementing operations. The cement job was pumped with 433 barrels of 13.5 ppg cement. The cement was displaced with 303 bbls of 9.5 ppg brine and the plugs bumped and held for 5 minutes. Floats held. 112 bbls of good cement were observed after circulating a bottoms up from the liner top packer indicating the entire lateral is cemented. Summary All casing is cemented in accordance with 20 AAC 25.030 and each hydrocarbon zone penetrated by the well is isolated. Based on engineering evaluation of the wells referenced in this application, ConocoPhillips has determined that this well can be successfully fractured within its design limits. SECTION 7 – PRESSURE TEST INFORMATION AND PLANS TO PRESSURE- TEST CASINGS AND TUBINGS INSTALLED IN THE WELL 20 AAC 25.283(a)(7) On 09/16/2025 the 10-3/4” casing was pressure tested to 3,000 psi for 30 minutes On 09/22/2025 the 7-5/8” casing was pressure tested to 4,000 psi for 30 minutes. On 10/09/2025 the 4-1/2” tubing was pressure tested to 4,200 psi for 30 minutes. On 10/09/2025 The 7-5/8” casing by 4-1/2” tubing annulus was pressure tested to 3,850 psi for 30 minutes.

The Torok Oil Pool is comprised of thinly interbedded sandstone, siltstone, and silty shale layers. The sandstone and siltstone components are litharenites, moderately to well sorted, and very fine grained. The silty shales are composed of clay-rich, moderately to poorly sorted silt and clay. The estimated fracture pressure for the Moraine interval is approximately 12.5-13.5 ppg. The overlying confining interval of the Torok Formation consists of mudstones and siltstones with a thickness of approximately 850’ TVD along the 3T-622 trajectory. The top of the Torok confining interval in the well starts at 7,041 MD (-4,098 TVDSS). The estimated fracture gradient of the overlying Torok formation is approximately 0.82 psi/ft. The underlying confining zone below the Base Moraine consists of lower Torok, HRZ, and Kalubik shales totaling approximately 500’ TVD. The estimated fracture gradient for this section ranges from 15-18 ppg, with the gradient increasing down section. The Base Moraine is estimated from seismic to be at -5,120’ TVDSS along the length of the well. The estimated formation pressure within the Torok Oil Pool is 2,285psi at a depth of 5,200’ TVDSS. SECTION 10 – LOCATION, ORIENTATION AND A REPORT ON MECHANICAL CONDITION OF EACH WELL THAT MAY TRANSECT CONFINING ZONE 20 AAC 25.283(a)(10) ConocoPhillips has formed the opinion, based on following assessments for each well and seismic, well, and other subsurface information currently available that none of these wells will interfere with containment of the hydraulic fracturing fluid within the one-half mile radius of the proposed wellbore trajectory. Casing & Cement assessments for all wells that transect the confining zone: 3T-616: The intermediate casing cement job was pumped with 117 bbls of 14.0ppg with BMII lead cement and 58bbls of 15.3ppg tail cement. Plugs bumped and floats held. Source: Laserfiche WebLink 224-138 3T-616 PB1: The abandonment plug consisted of 42bbls of 16.3ppg cement laid in at the heel of the wellbore into the 7-5/8” intermediate casing shoe. The cement top was then tagged at 9,065’ MD/5,104’ TVD/5,053’ TVDSS with 12klbs. Source: Laserfiche WebLink 224-138 Nuna-1: The 7-5/8” casing was cemented in place on 2/16/2012. The cement report indicates that the job was pumped with 40 bbls 15.8ppg Class G cement. The plugs bumped and partial returns were observed during the job (pg. 187 at link). Suspension operations began on 1/18/2023 where a cement retainer was set at 9,062’ CTMD and 65bbls of Class G cement was pumped through the retainer. Another retainer was placed at 7,965’ MD and 48bbls of 15.8ppg cement was pumped with another 12 bbls laid on top of the retainer. The TOC was tagged at 7,003’ MD and a MIT-T performed to 1700 psi, witnessed by AOGCC on 3/1/2023. A tubing cut was completed at 6,960’ MD and the 4.5” tubing was then pulled. A CIBP was set at 6,910’ MD and tested to 1,200 psi. Cement was laid on top of the retainer and tagged at 6,621’ MD two times with 12klbs. Source: Laserfiche WebLink 211-155 3T-613: The intermediate casing cement job was pumped with 211 bbls of 14.0ppg lead cement and 59 bbls of 15.3ppg tail cement. Plugs bumped and floats held. Source: Laserfiche WebLink 225-036 3T-619: The intermediate cement job was pumped with 191 barrels of 14.0 ppg lead cement, followed with 61 barrels of 15.3 ppg tail cement. This was displaced with 520 barrels of 10.0 ppg NAF. The plug bumped, pressure was bled off, and floats were confirmed to be holding. A cement bond log indicates competent cement with a cement top @ 7,652’ MD (3,974’ TVDRKB). The intermediate column of good cement of 437’ MD in combination with the weaker column of cement above in excess of 2600’ MD meets regulation (AOGCC’s approval on 09/03/2025). Source: 225-079 - Laserfiche WebLink SECTION 11 – LOCATION OF, ORIENTATION OF AND GEOLOGICAL DATA FOR FAULTS AND FRACTURES THAT MAY TRANSECT THE CONFINING ZONES 20 AAC 25.283(a)(11) CPAI has formed the opinion, based on seismic, well, and other subsurface information currently available that four faults transect the Torok Oil Pool reservoir within one half mile radius of the 3T-622 wellbore trajectory. These faults are all estimated to strike NE-SW and are shown in Plat 1. Three faults intersect the 3T-622 well trajectory at 12,515’ MD (Fault 1) and 15,175’ MD (Fault 2) and 20,802’ MD (Fault 3), respectively, while the fourth fault is past the toe of the well and is not intersected. Faults 1,2, and 3 are interpreted to be upthrown on the northern side, between 20-30 ft. The fourth fault in the ½ mile radius area surrounding the 3T-622 is also upthrown to the North. Throw on the fault uncertain as it has not been penetrated by any offset wells but is estimated to be between 40’ to 70’. All faults in the ½ mi area of the 3T- 622 are difficult to trace on the seismic data, due to a) lack of fine-scale resolution at the Torok Oil Pool level and b) lack of reflectivity in the overlying Torok shales, the result of the monotonous shaly lithology. Fault #1 & #4 (past the toe) have the potential to penetrate through the overburden into the overlying hydrocarbon bearing Coyote Oil Pool; however, due to the shaly overburden and horizontal stress acting on the fault (interpreted to be 15.8 ppg at the fault’s mapped orientation) the presence of the faults will not interfere with containment. Fault 2 and Fault 3 are interpreted to be confined to the Moraine interval as they are not explicitly mapped on seismic and are interpreted only on well log correlation. If there is any indication that a fracture has intersected any mapped fault (or any other faults unmapped to date) during fracturing operations, ConocoPhillips will go to flush and terminate the stage immediately. SECTION 12 – PROPOSED HYDRAULIC FRACTURING PROGRAM 20 AAC 25.283(a)(12) 3T-622 was completed in October 2025 as a horizontal producer in the Torok formation. The well is completed with a 4.5” tubing upper completion and a cemented 4.5” liner with 25 dart activated sliding sleeve and 3 ball drop activated sliding sleeve lower completion. The first stage frac will be pumped through a toe initiator valve in the toe of the lateral. After the 1st stage, a ball/dart will be dropped to shift open the 2nd stage sleeve and isolate the first stage. A frac will then be pumped through the 2nd stage. Balls/darts will continue to be dropped to provide isolation from the previous stage and open each subsequent stage. Proposed Procedure: Halliburton Pumping Services: 1. Conduct Safety Meeting and Identify Hazards. Inspect Wellhead and Pad Condition to identify any pre- existing conditions. 2. Ensure the frac tree was tested to ~10,000 psi at rig. 3. Ensure all pre-frac well work has been completed and confirm the tubing and annulus are filled with a freeze protect fluid to 2,278’ MD / 2,153’ TVD. 4. Ensure the 10-403 Sundry has been reviewed and approved by the AOGCC. 5. MIRU 40 clean insulated Frac tanks (450 bbls usable volume per tank), with a berm surrounding the tanks that can hold a single tank volume plus 10%. Load tanks with either seawater or treated produced water. 6. MIRU HES Frac Equipment. 7. PT Surface lines to ~9,500 psi using a Pressure test fluid. 8. Test IA Pop off system to ensure lines are clear and all components are functioning properly. 9. Bring up pumps and increase annulus pressure to 3,500 psi as the tubing pressures up. 10. Pump Frac Stages 1 through 29 by following attached pump schedule at ~37 bpm with a maximum expected treating pressure of ~7,050 psi. 11. The well is ready for Post Frac well prep/production tree installation, coiled tubing cleanout and flowback. SECTION 13 – POST-FRACTURE WELLBORE CLEANUP AND FLUID RECOVERY PLAN 20 AAC 25.283(a)(13) Flowback will be initiated through a de-sander unit until the fluids clean up at which time it will be turned over to production for initial clean up production.
