Casing & Cement Assessments:
The 10-3/4” casing cement report on 06/09/2025 was pumped with 430 barrels of 11.0 ppg lead cement and 57
barrels 15.8 ppg tail cement. This was displaced with 223 bbl 9.8 ppg spud mud. The plug bumped and the floats
held.
The 7-5/8” casing cement report on 06/16/2025 shows that the job was pumped as designed, indicating
competent cementing operations. The cement job was pumped with 169 barrels of 14.0 ppg lead cement,
followed with 59 barrels of 15.3 ppg tail cement. This was displaced with 455 barrels of 10.0 ppg RheGuard 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 @ 6,218’ MD (3,908’ TVD).
The 4-1/2” liner cement report on 07/01/2025 shows the job was pumped as designed, indicating competent
cementing operations. 93 bbls of cement were lost during the job but 10 bbls of cement were observed after
circulating a bottoms up from the liner top packer indicating the entire lateral is cemented. The cement job was
pumped with 373 barrels of 13.5 ppg cement. The cement was displaced with 9.5 ppg CI NaCl brine and the
plugs bumped and held for 5 minutes. Floats held.
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 9 – DATA FOR FRACTURING ZONE AND CONFINING ZONES 20 AAC
25.283(a)(9)
CPAI has formed the opinion, based on seismic, well, and other subsurface information currently available that:
The fracturing zone, the Torok Oil Pool, has an average thickness of approximately 260 ft TVD over the course
of the lateral section of well 3T-605, from where it intersects the top formation at 10,205 MD (8,984’ TVDSS) to
the TD of the well. 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 800’ TVD along the 3T-605 trajectory. The top of the Torok confining interval in the well starts at
7,245’ MD (4,188’ 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 5,250 ft 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:
3S-606: The 7-5/8” casing cement report on 2/11/2024 shows that the job was pumped as designed, indicating
competent cementing operations. The cement job was pumped with 111 barrels of 15.3 ppg with BM-II (Bridge
Maker II), followed with 29 barrels of 15.3 ppg without BMII. The plug was bumped, pressure increased to 1500
psi and held for 5 minutes. A cement bond log indicates competent cement with a cement top @ 3,950 MD
(3,164’ TVD).
3S-617: The 7 & 5/8” casing cement report on 11/5/2023 shows that the job was pumped as designed, indicating
competent cementing operations. The cement job was pumped with 142 barrels of 15.3 ppg. The plug was not
bumped. Pressure was being monitored and no pressure built up indicating that the floats held. A cement bond
log indicates competent cement with a cement top @ 3,841’ MD (3,157’ TVD).
3S-624: The 7-5/8” casing cement report on 12/24/2023 shows that the job was pumped as designed, indicating
competent cementing operations. The cement job was pumped with 125 barrels of 15.3ppg primary cement with
LCM and 22 barrels of 15.3ppg primary cement without LCM. The plug was bumped and the floats held. A
cement bond log indicates competent cement with a cement top @ 3,435’ MD (2,778’ TVD).
3T-603: The 7-5/8” casing cement report on 10/29/2024 shows that the job was pumped as designed, indicating
competent cementing operations. The cement job was pumped with 203 barrels of 14.0 ppg lead cement,
followed with 31 barrels of 15.3 ppg tail cement, displaced with 440 barrels of 9.6 ppg WBM. The plug bumped
and floats held. A cement bond log run on 11/02/24 indicates competent cement with a cement top @ 5,768’
MD (3,792’ TVD).
3T-608: The 7-5/8” casing cement report on 10/28/2024 shows that the job was pumped as designed, indicating
competent cementing operations. The cement job was pumped with 203 barrels of 14.0 ppg lead cement with
BMII, followed with 31 barrels of 15.3 ppg tail cement, displaced with 463 barrels of 9.5 ppg FWP. The plug
bumped, bled off pressure and pressure and floats were confirmed to be holding. A cement bond log indicates
competent cement with a cement top @ 5,768 MD (3,843’ TVD).

ODSN-17: According to the Pioneer Natural Resources Operation Summary Report on the AOGCC website, on
9/27/2010, while displacing the 7" liner cement job, the plugs landed early but did not hold much pressure, and
pumping was continued pas the estimated stroke count and shoe track volume (the overdisplacement volume
was estimated to be 28 bbls). This resulted in a wet shoe which was confirmed by pumping mud from surface.
On 10/1/2010, the squeeze job (15 bbls of 15.8ppg cement, 13 bbls of SW, 102 bbls of 10.1ppg mud) was
performed as planned.
ODSN-17L1: Same as above
ODST-47: According to the Pioneer Natural Resources job log on the AOGCC webiste, on 9/13/2012, the 7-
5/8"" casing cement job (55 bbls of Premium Class G tail cement at 15.8ppg) was pumped with partial returns
(74 bbls) and the post job cement analysis showed ~70 psi of lift pressure. The cement bond log shows 52' of
strong bond and 95' with partial bond of a total of 147' bonding.
According to the Caelus Natural Resources job log on the AOGCC website, on 4/7/2019, the squeeze job (200
bbls in the formation and 9 bbls in the lateral tubular) was performed. The top of cement was at 12,223' CTM.
ODSN-17/L1 wells are not within the AOR. Also, KRU 3S-602 and NDST-02PH are within the AOR and are included in the
Moraine Frac AOR Spreadsheet reviewed by AOGCC. See attached emails. -A.Dewhurst 28AUG25
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
a fault transects the Torok Oil Pool reservoir within one half mile radius of the 3T-605 wellbore trajectory. The
fault intersects the 3T-605 well trajectories at 12,666’ MD, it is interpreted to have offset the toe section of the
3T-605 well upwards by <5ft. The fault trace is below seismic resolution, but an initial strike interpretation is
shown in Plat 1. The fault is interpreted to not affect overburden integrity and therefore its presence will not
interfere with containment.
If there is any indication that a fracture has intersected the 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-605 was completed in July 2025 as a horizontal injector in the Torok formation. The well is completed with a
4.5” tubing upper completion and a cemented 4.5” liner with a dart 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 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. 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 2,288’ MD / 2,164’ TVD.
4. Ensure the 10-403 Sundry has been reviewed and approved by the AOGCC.
5. MIRU 25 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. Perform DFIT after opening the Alpha Sleeve according to the attached pump schedule. Ensure sufficient
volume is pumped to load the well with Frac fluid, prior to shut down. Resume pumping to pump Frac Stage
1.
11. Pump Frac Stages 2 through 24 by following attached pump schedule (skipping stages 19 and 20) at ~37
bpm with a maximum expected treating pressure of ~8,500 psi. Stages 19 and 20 will be skipped due to
proximity of the fault at 12,666’.
12. The well is ready for Post Frac well prep/production tree installation, coiled tubing cleanout and flowback.
Based on tubing test to 4200 psi, differential pressure max of 3818 psi, IA hold of 3500 psi,
max surface frac pressure limited to 7318 psi. CDW 08/26/2025
pp
~8,500 psi.
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.

CPAI has not identified any wells for increased monitoring during frac. Nuna 1 as close enough to proposed frac at 3T-605 that it will be watched and may effect pumping of 3T-605 frac. Nuna 1 is proposed for perf and wash as Coyote is not isolated by cement. Max frac propped half-length of max 210 ft at toe and 180 ft at 10513 ft (shallowest frac port).

Allen,
I’m completing my review of the KRU 3T-605 frac sundry and have a question about the Area of Review.
x I’m showing that the NDST-02PH and possibly the KRU 3T-602 wells are within the ½-mile AOR
x I’m also showing that the ODSN-17/L1 are down in the Nuiqsut and not within the AOR
Would you please conƱrm the above and send an updated AOR table (PDF) if so?
Thanks,

Conditions of Approval:
Approval is granted to run the LWD-Sonic on upcoming well with the following provisions:
1. CPAI will provide a written log evaluation/interpretation to the AOGCC along with the log as
soon as they become available. The evaluation is to include/highlight the intervals of competent
cement that CPAI is using to meet the objective requirements for annular isolation, reservoir
isolation, or confining zone isolation etc. Providing the log without an evaluation/interpretation
is not acceptable.
2. LWD sonic logs must show free pipe and Top of Cement, just as the e-line log does. CPAI must
start the log at a depth to ensure the free pipe above the TOC is captured as well as the TOC.
Starting the log below the actual TOC based on calculations predicting a different TOC will not
be acceptable.
3. CPAI will provide a cement job summary report and evaluation along with the cement log and
evaluation to the AOGCC when they become available
4. CPAI will provide the results of the FIT when available.
5. Depending on the cement job results indicated by the cement job report, the logs and the FIT,
remedial measures or additional logging may be required.
.58'67
CPAI’s request to allow BOPE testing on a 21-day interval is approved with the following
conditions:
- CPAI must continue to implement the Between Wells Maintenance Program as approved
by AOGCC.
- The initial test after rigging up BOPE to drill a well must be to the rated working pressure
as provided in API Standard 53.
- CPAI is encouraged to take advantage of opportunities to test within the 21-day time limit.
- CPAI must adhere to original equipment manufacturer recommendations and replacement
parts for BOPE.
- Requests for extensions beyond 21 days must include justification with supporting
information demonstrating the additional time is necessary for well control purposes or to
mitigate a stuck drill string.

Re: Application for Permit to Drill 3T-605
Dear Sir or Madam:
ConocoPhillips Alaska, Inc. hereby applies for a Permit to Drill an onshore Moraine Injector well from the 3T drilling pad.
The intended spud date for this well is 6/13/2025. It is intended that Doyon 142 be used to drill the well.
3T-605 will utilize a 13 1/2” surface hole drilled to TD and 10 3/4” casing will be set and cemented to surface. As noted in
section 4 of the attached proposed drilling program, the low maximum anticipated surface pressure of the well allows use of a
three preventer BOPE per 20 AAC 25.035 (e) (1) (A) (i-iii). The fourth preventer will contain solid body pipe rams that will
be sized for the intermediate casing string. The 9 7/8” intermediate hole will be drilled and set in the Moraine reservoir. A 7
5/8” casing string will be set and cemented from TD to secure the shoe and cover 250’TVD above any hydrocarbon-bearing
zones (Coyote).
The production interval will be comprised of a 6 1/2” horizontal hole that will be landed and geo-steered in the Moraine
formation. The well will be completed as a fracture stimulated Injector with 4 1/2” liner and frac sleeves, cemented from TD to
the liner top. The upper completion will include a production packer with GLM’s and a downhole guage tied back to surface.
A variance is requested for a BOPE test interval of 21 days for this project. Doyon 142 is a strong participant in the CPAI

Surface Hole:
A water based spud mud will be used for the surface interval. Mud engineer to perform regular mud checks to maintain
proper specifications The mud weight will be maintained at H9.8 ppg by use of solids control system and dilutions where
necessary.
Intermediate:
Fresh water polymer mud system. Ensure good hole cleaning by pumping regular sweeps and maximizing fluid annular
velocity. Maintain mud weight at or below 9.6 ppg for formation stability and be prepared to add loss circulation
material if necessary. Good filter cake quality, hole cleaning and maintenance of low drill solids (by diluting as required)
will all be important. The mud will be weighted up to 9.5 ppg before pulling out of the hole.
Production Hole:

disposal well at the 1B Facility. If needed, excess cuttings generated will be hauled to Milne Point or Prudhoe Bay Grind
and Inject Facility for temporary storage and eventual processing for injection down an approved disposal well, or stored,
tested for hazardous substances, and (if free of hazardous substances) used on pads and roads in the Kuparuk area in
accordance with a permit from the State of Alaska.
15. Drilling Hazards Summary
13 1/2" Hole / 10 3/4” Casing Interval
Event Risk Level Mitigation Strategy
Conductor Broach Low Monitor cellar continuously during interval.
Well Collision Low Follow real time surveys very closely, gyro survey as
needed to ensure survey accuracy.
Gas Hydrates Low If observed – control drill, reduce pump rates and
circulating time, reduce mud temperatures
Hole Swabbing on Trips Moderate Trip speeds, proper hole filling (use of trip sheets),
pumping out
Washouts/Hole Sloughing Low Cool mud temperatures, minimize circulating times
when possible
Running sands and gravels Low Maintain planned mud properties, increase mud
weight, use weighted sweeps
Lost Circulation Moderate Monitor ECDs for signs of packoff before losses occur.
Keep hole clean and utilize LCM sweeps to regain
circulation.

Hole swabbing on trips Moderate Reduce trip speeds, condition mud properties, proper
hole filling, pump out of hole, real time ECD monitoring
Abnormal Reservoir Pressure Low Well control drills, check for flow during connections,
increased mud weight
Differential Sticking Moderate Uniform reservoir pressure along lateral, keep pipe
moving, control mud weight
Running Liner to Bottom Moderate Properly clean hole on the trip out with BHA, perform
clean out run if necessary, utilize super sliders for
weight transfer if needed, monitor T&D real time
Well Proximity Risks:
3T is a multi-well pad, with only a few existing wells. Directional drilling / collision avoidance information as required by
AOGCC 20 ACC 25.050 (b) is provided in the following attachments.
Drilling Area Risks:
Reservoir Pressure: Unlikely to encounter any abnormal pressure, however, the rig will be prepared to weight up if required.
Weak sand stringers could be present in the overburden. LCM material will be available to seal in losses in the intermediate
section.
The overburden logs will be evaluated to ensure no hydrocarbon bearing zones are above the known Coyote. If identified, the
primary intermediate cement job will be replanned to cover the zone as per the agency regulations.
Lost Circulation: Standard LCM material and well bore strengthening pills are expected to be effective in dealing with lost
circulation if needed.
Good drilling practices will be stressed to minimize the potential of taking swabbed kicks.
