2023 Annual Reservoir Surveillance Report
Summary of the Enhanced Recovery Project
Enhanced Recovery
Enriched water‐alternating‐gas (EWAG) was the main enhanced oil recovery (EOR) process for the Kuparuk Field
in 2023. In September of 2018, NGL imports from Prudhoe Bay (PBU) were brought back into Kuparuk for the first
time since 2014 and continued until September of 2021. With the cessation of Prudhoe Bay NGL imports in 2021,
only Kuparuk indigenous NGLs were blended for gas enrichment in 2023. In total, 66 injectors and 20 drillsites in
the Kuparuk Field received enriched gas injectant between January and December of 2023.
Kuparuk Field manufactures enriched gas injectant at two of its Central Processing Facilities (CPFs). Enriched gas
injectant is manufactured by blending together produced lean gas (LG) and indigenous natural gas liquids (NGLs).
The NGL pump atCPF1 was out of continuous service starting on 10/3/2023. From this date to the end of 2023,
injected gas at CPF1 was not blended with indigenous NGLs.
EWAG
Small‐Scale EOR (SSEOR and SSEORX)
The original SSEOR and SSEORX drillsites include: 1A, 1Y, and 2Z. Of these drillsites, 1Y received EWAG
periodically throughout 2023. The combined 12‐month average enriched gas injection rate was 1.6 mmscf/d.
Large‐Scale EOR (LSEOR)
The original LSEOR drillsites include: 1F, 1G, 1Q, 1R, 2A, 2B, 2C, 2D, 2F, 2G, 2H, 2K, 2M, 2T, 2U, 2V, 2W, 2X, and 3F.
Of these drillsites, 1F, 1Q, 2A, 2B, 2C, 2H, 2K, 2M, 2T, and 3F received MI in 2023. The combined 12‐month average
enriched gas injection rate was 24.4 mmscf/d.
EOR Expansions
Expansions to the original LSEOR occurred over multiple phases and now include drillsites 1B, 1C, 1D, 1E, 1L, 2S,
3B, 3G, 3H, 3O, 3Q and 3S. Of these drillsites, 1B, 1C, 1D, 1E, 1L, 2S, 3G, and 3O received enriched gas in 2023.
The combined 12‐month average MI injection rate was 57.6 mmscf/d.
IWAG
Volumes of lean gas available after blending enriched gas were injected into the field as immiscible water‐
alternating‐gas (IWAG) periodically throughout 2023. Drillsites 1B, 1C, 1D, 1E, 1F, 1L, 1Y, 2S, 3F, and 3G received
lean gas in 2023. The combined 12‐month average LG injection rate was 1.9 mmscf/d.

Re: Kuparuk River Oil Pool – Proposed Injection Profile Survey Plan for 2024
Dear Commissioner Chmielowski,
In compliance with Rule 4, Conservation Order No. 198B, ConocoPhillips Alaska, Inc., operator of the Kuparuk River
Oil Pool, is hereby submitting the proposed injection profile survey plan for 2024.
There were fourteen injection surveys reported for the Kuparuk River Oil Pool to the AOGCC in 2023 (Attachment 5). In
2024, we expect to conduct approximately ten injection surveys, including initial surveys for new wells prior to initial
sustained injection.
Additionally, Attachment 6 provides data for the thirteen production surveys conducted in 2023.
If you have any questions concerning this data, please contact Adam Schnellbaecher at (907) 263-4188.
Sincerely,
Donald Allan
Manager, GKA Asset Development

Enriched Gas Injectant Composition
Enriched gas Injectant is manufactured at two Central Processing Facilities, CPF‐1 and CPF‐2. The compositions
of both the lean gas and enriching fluids (NGLs) are measured periodically throughout the year. Detailed
compositional analyses and MMP (target of 3300 psia) of the enriched gas from each CPF is provided in tabular
form below. A lower MMP implies a higher NGL content in the enriched gas.
NGL imports from Prudhoe Bay ceased in September of 2021, after which “indigenous” Kuparuk NGLs were the only
enrichment source for blending. The resulting leaner injection composition marked the transition from MWAG
(miscible water alternating gas) to an EWAG (enriched water alternating gas) tertiary flood.

LSEOR Development Plan
During 2023, the Greater Kuparuk Area (GKA) averaged 8,692 BPD of indigenous NGLs for an annual average of 107
million standard cubic feet per day (MMSCFD) of injectant manufactured, 94.6 MMSCFD of which was used for
downhole injection for tertiary recovery. NGL imports from Prudhoe Bay ceased in September of 2021. Of the
total enriched gas production in 2023, 83.6 MMSCFD was injected into the main Kuparuk Field. Within the main
Kuparuk Field, 0.7 MMSCFD was allocated for SSEOR and SSEROX, and 82.0 MMSCFD was allocated for the LSEOR
and LSEORX expansion which included drillsites 1F, 1Q, 2A, 2B, 2C, 2H, 2K, 2M, 2T, 3F, 1B, 1C, 1D, 1E, 1L, 2S, 3F,

Dear Commissioner Chmielowski,
In compliance with Rule 7, Conservation Order No. 456A and Rule 9 Item C, Area Injection Order 21C,
ConocoPhillips Alaska, Inc., operator of the Meltwater Oil Pool, is hereby submitting the proposed pressure survey
plan for 2024.
There were four pressure surveys was reported for the Meltwater Oil Pool to the AOGCC in 2023. In 2024, we do not expect to
conduct pressure surveys as a decision has been taken to abandon the reservoir.
If you have any questions concerning this data, please contact Adam Schnellbaecher at (907) 263-4188.

elevated outer annulus (OA) pressures. Based upon the information gathered, and technical analyses completed to
date, it is likely the initial migration of injected fluids out of the Bermuda interval was a result of a large pressure
differential between injectors and producers. This pressure differential was exacerbated by low permeability and
stratigraphic and/or structural discontinuities within the Bermuda interval.
The Operator has continued to monitor OA pressures on a routine basis. There are currently no indications that
injection has occurred out of the Bermuda interval in 2023. Gas sampling was discontinued once water injection was
implemented as sampling of gas will no longer indicate a loss of containment. In addition, the extended bleed of the
outer annulus of well 2P-431 is continuously monitored in an effort to deplete the source charging the outer annulus.
2023 IA and OA pressure trends for all wells are included in Attachment 7.

Results of Monitoring Inner and Outer Annuli
Summary of results of inner and outer annulus monitoring for all production wells, injection wells, and any wells that
are not cemented across the Meltwater Oil Pool and are located within ¼-mile radius of a Meltwater injector.
Information below contains the inner annulus (IA) and outer annulus (OA) pressures for each well, the well head
injection pressure (WHIP) for injection wells, and flowing tubing pressure (FTP) for production wells. Any WHIP above
2,900 PSI is attributed to a shut-in event for that well.

Development Plan and Operational Review
Development
A detailed study was conducted in 2021 to evaluate the economic feasibility of the 2P drillsite, following which
a decision was taken to abandon the Meltwater reservoir and P&A the wells.
Pipeline Operations
All pipelines to and from drillsite 2P were abandoned in place in summer 2022. The lines will be removed from
service pending confirmation that they meet specific ADEC requirements to be de-inventoried, cleaned, blinded,
and labeled.
Exploration/Delineation
No further exploration work is currently planned for the Bermuda interval.
Surveillance plans for 2024
In accordance with AIO21C Rule 9 Item I the following bullets are key to 2024 reservoir surveillance plans.
Continuous monitoring of OA pressures through the SCADA system and bleed as necessary, till the wells
are P&A’ed.

2023 Annual Reservoir Surveillance Report
Summary of the Enhanced Recovery Project
Tabasco produced 427 thousand barrels (MSTB) of oil, 77 million standard cubic feet (MMSCF) of gas and 5.16
million barrels of water (MMBW) during 2023. Water injection was 4.9 MMBW over the same period. Cumulative
oil, gas, and water production through year‐end 2023 were 22.7 million barrels of oil, 3.75 billion standard cubic
feet of gas, and 130.6 MMBW of water, respectively. Cumulative water injection through year‐end 2023 was 140.4
MMBW. The cumulative year‐end 2023 injection‐withdrawal ratio, based on current formation volume factors, is
estimated at 0.90 for Tabasco.
Year‐end 2023 Tabasco well count (Kuparuk River Unit drillsite 2T) was:
9 completedProducers: 4 online
3 completedInjectors: 2 online
Well 2T‐204 had its perforations isolated with cement in 2013 due to low productivity and is not economic to
produce at this time. In 2018, one producer was offline due to high watercut. One producer was offline due to a
stuck coiled tubing string from a packer leak repair job. One producer was converted to an injector. As of December
31, 2023, Tabasco oil pool was producing with four producers and two injectors online. One of the producers, 2T‐
215 is shut in awaiting a RWO in 2024.
Water breakthrough has occurred at all producers in the Tabasco Oil Pool. Production and injection logs, coupled
with the structural positions and water breakthrough histories of the producers, suggest that the water
production mechanism is dominated by gravity‐induced slumping and flow through high‐permeability facies.

Results of Well Allocation
A minimum of two well tests per month are conducted on production wells. Fluid samples are obtained on a
regular basis, and water cut corrections are applied to well tests as required based on subsequent lab analysis.
Generally, good agreement was observed for water cuts comparing phase dynamics and shakeout analysis.
Production volumes are tracked through an automated production monitoring SCADA system (IP.21). In 2002,
Tabasco switched from an allocation factor of 1.0 to floating production allocation factors. Tabasco 2023

2023 Annual Reservoir Surveillance Report
Development Plans and Operational Review
Tabasco injection-withdrawal ratios are monitored to maintain an instantaneous value of approximately 1.0.
Adjustments to injection and/or production rates are made to achieve this to maintain pressure support for the
Tabasco reservoir and keep gas in solution. The 2023 injection strategy continued replacing voidage by splitting water
injection between two injectors: 2T-201 and 2T-217A. 2T-209 was shut-in in 2020 when a high shut-in bottomhole
pressure was measured in the well. The high pressure showed inadequate offtake from the 2T-209 pattern and the
injector was shut-in in an abundance of caution to prevent any out of zone injection. The injection rates in the
remaining injectors (2T-201 and 2T-217A) were increased to offset the loss of injection from 2T-209 to maintain an
I/W of 1.0.
In November 2014, chemical tracers were injected into the two in-service injectors, 2T-201 and 2T-217A. From 2015
to 2017, all active producers were sampled on a regular basis for the presence of these tracers. The concentration
and duration of the chemical tracer breakthrough was used to evaluate heterogeneities within the Tabasco reservoir
and found the majority of current sweep to be taking place in the periphery of the field. This finding was key to the
proposal to convert the 2T-209 from production to injection in 2019.
Waterflood operations continued to be optimized in 2023. The reservoir management strategy is predicated upon
injecting water deep into the central canyon and produce from the periphery. These high permeability facies are
prevalent in the central canyon injectors but not in the peripheral wells. The gravity slumping of the injected water
combined with recovery higher up in the structure leads to a gravity stable waterflood. This has been key in keeping
Tabasco water cut under control and improve overall oil recovery. Among Tabasco producers 2T-218, is approaching
high watercut (> 96%) which in future may make the well uneconomic. To flatten it’s watercut rise, drawdown in 2T-
203 has been increased by ramping up the ESP of the well and diverting some fluids from 218 to 203. As a result 218
watercut has gone down slightly whereas more oil is being recovered from 2T-203. In 2022 the producer 2T-208 was
worked over and a bigger ESP with a higher drawdown was run in the well. The actions in 2021 and 2022 have slowed
the watercut progression in Tabasco and this strategy will be continued in the near future.
No additional development drilling wells are planned at this time.

Tarn Oil Pool
2023 Annual Reservoir Surveillance Report
Summary of EOR Project and Reservoir Management Summary
Background
In 1998, Arco Alaska, Inc. received approvals for formation of the Tarn Oil Pool in the Kuparuk River Unit, an Area
Injection Order for Tarn, expansion of the Kuparuk River Unit, and formation of the Tarn Participating Area. The
Tarn Pool Rules and Area Injection Order were approved on July 21 and July 20, 1998, respectively. The Unit
Expansion and Participating area were approved effective July 1, 1998.
Construction of the Tarn road, pads, power lines, and pipelines took place in the 1998-1999 winter construction
season. Tarn development drilling commenced in April of 1998. Tarn production began in July 1998 and injection
of miscible injectant (MI) began in November 1998. Tarn switched to a miscible water-alternating gas (MWAG)
recovery process in July 2001.
Progress of EOR Project
The permanent 12” water injection line was completed and brought on-line in July 2001. This allowed Tarn to
switch from a strictly MI flood to a MWAG recovery process which increases ultimate recovery from the Tarn
reservoir. Water injection capacity has been good, and total fluid injection has been able to match reservoir
voidage.
Through July 2014, the Tarn MWAG process used Kuparuk spec MI injected above the minimum miscibility
pressure. Refer to Section 7 of the Kuparuk Annual Surveillance Report for compositional analysis of the Kuparuk
spec MI. Following the cessation of imported natural gas liquids from the Prudhoe Bay Field Central Gas Facility
at the end of July 2014, immiscible water-alternating gas utilizing lean gas was applied to the Tarn reservoir.
On September 2018, NGL imports from Prudhoe resumed, thereby enabling the MWAG process to return to Tarn.
In 2021 NGL imports from Prudhoe had ceased. Tarn now receives an enriched gas (or blend gas) composed of
lean gas and GKA NGL’s.
Reservoir Management Summary
In 2023, Tarn produced 1.59 million barrels of oil, 3.57 million barrels of water (MMBW), and 2.24 billion standard
cubic feet (BSCF) of gas. The injection totals for 2023 were 3.98 BSCF enriched gas, and 4.6 MMBW. At the end of
2023, the cumulative injection/withdrawal ratio for Tarn was 1.15. Plans are to continue maintaining reservoir
pressure by balancing monthly production and injection rates.

Development Plan and Operational Review
Development Drilling
No development wells were drilled at Tarn in 2023.
Producer to Injector Conversions
No well service conversion projects were executed in Tarn in 2023.
Artificial Lift
Tarn was originally designed to artificially lift producers using miscible gas. However, paraffin deposition in the tubing string
occurs when the production fluid temperature falls below the cloud point of 92°F. This is the case of longer reach wells and
lower liquid rate production wells. Excessive paraffin build‐up and the high frequency of required paraffin scrapes in some
wells led to a change in artificial lift methodology towards surface‐powered downhole jet pumps. In 2001, after successful
pilot tests in 1999 and 2000, 13 of the gas lifted wells were converted to jet pump using hot produced water as power fluid.
This technique has proven to be very successful in mitigating paraffin deposits. Slickline scrapes and hot oil treatments was
virtually eliminated leading to production increases of about 10%. Unfortunately, the untreated saline produced water
injected down the inner annuli (power fluid) has accelerated tubing and casing corrosion.
Three well integrity failures occurred on jet‐pumped wells due to both tubing and well casing corrosion in 2006‐ 2007: 2L‐321,
2N‐318, and 2N‐305. These wells were shut‐in and secured. Wells 2N‐305 and 2N‐318 were both sidetracked in 2009. A
workover to install an additional casing string was successfully completed for 2L‐321 during 2008.
In 2009 and 2010, three additional wells were shut‐in after failing mechanical integrity tests: 2N‐319, 2N‐303, and 2L‐313.
These wells were in jet pump service when the failures occurred. Wells 2N‐319 and 2N‐303 were both sidetracked in 2014.
Well 2L‐313 will likely remain shut‐in and secured until a rotary sidetrack is executed targeting a more prolific area of the
reservoir.
After water breakthrough occurs in producing wells, paraffin deposition is less likely due to increased well flowing
temperatures resulting from the heat capacity of water being greater than that of oil. Consequently, completion designs and
alternatives to jet pumps are being considered for new and existing wells. All new producers drilled in 2014‐2015 utilized lift
gas for artificial lift.
In 2016, a mixed approach to artificial lift was adopted. The wells with the highest downtime & cost for paraffin remediation,
combined with an expectation of short remaining tubular life were targeted for jet pumps. This resulted in 2L‐330 being
converted from gas lift to jet pump and brought the Tarn total to five active jet pump wells.
In the past few years, the artificial lift strategy has remained largely unchanged. In 2018, the 2N‐304 was converted from
surface powered jet pump to gas lift to reduce water handling costs and corrosion tendency. The well has successfully
produced on gas lift with no downtime due to paraffin remediation. In 2019, a similar artificial lift change was done in 2L‐321
where the lift mechanism was changed to gas lift from jet pump. The well has a higher tendency for paraffin plugging due to
the smaller size of tubing. To mitigate plugging, the well undergoes frequent hot diesel flushes and slickline scrapes. 2N‐339
underwent a Rig Workover (RWO) to replace leaking tubing. The well was put on jet pump service after RWO and oil production
has been restored. In 2020, 2L‐311 was found to have flow erosion in the sliding sleeve. Repeated attempts to lift the well
with jet pump failed due to the jet pump failing to seat and seal across the sleeve. To keep the well producing, the well was
converted to gas lift, following which 2L‐311 was put back into service. The year 2021 saw several changes in the field
management strategy for Tarn West End, which continues to exhibit high water cut as the area approached maturity. 2N‐333
watercut became uncompetitive as a result the well was recompleted by isolating the watered out perforations and adding
new perforations shallower. In a similar exercise the lower perforations of 2N‐347, and 2N‐329 have been isolated to reduce
water production, thus allowing the shallower perforations to continue to produce. The injection rates have been accordingly
adjusted to maintain a VRR of 1 in the area.
In 2021 measurement issues were also discovered with the 2L Accuflow test separator. After a cleanout of the accuflow, the
measurement issues improved, and it was discovered that the liquid rates in 2L is much lower than previously being measured.
Subsequently the micromotion meter was replaced recently in February 2022, after which reliable test results are currently
being obtained. In 2022 some wells in Tarn failed annular communication tests. Some of these failures were caused by leaking
orifice valves and were addressed in 2022, and some were repaired with RWO’s in 2023 (2L‐326 and 2N‐316). Two wells (2L‐
321 and 2N‐315) are in the plans for a rig workover.

Summary of Enhanced Recovery Project
Reservoir Management Summary
Torok Oil Pool produced 625 thousand barrels (MSTB) of oil, 837 million standard cubic feet (MMSCF) of gas and
2,395 thousand barrels of water (MBW) during 2022. Over the same period, 2,601 MBW, 0 MMSCF of lean gas and 0
MMSCF of MI were injected. Cumulative oil, gas, and water production through year-end 2022 was 2,164 MSTB,
3,017 MMSCF, and 8,146 MBW, respectively. Cumulative water, lean gas, and MI injection through year-end 2021
was 9,357 MBW, 372 MMSCF, and 271 MMSCF, respectively.
One new horizontal well was completed and brought online in 2023, producer 3S-615. Injector 3S-625 completed in
2022 finished its flowback and was placed on injection service. A third well, injector 3S-617, was drilled but will not
be completed and brought on injection until Q1 2024. Seven more wells, three producers and four injectors are
planned for drilling and completion in 2024.
Torok exploration well 3S-19 was plugged and abandoned.
Progress of EOR Project
With completion of injector 3S-625 the first fully supported pattern in the Torok was in operation in 2023. Early
indications are that voidage can be maintained.

Attachment 1
West Sak Oil Pool
2023 Annual Reservoir Surveillance Report
Summary of the Enhanced Oil Recovery Project
During 2023, there were 57 active producers and 59 active injectors in the West Sak Oil Pool. Waterflood continues
to be the primary method to improve oil recovery and maintain reservoir pressure at West Sak. Water is sourced from
the Seawater Treatment Plant (STP), Central Processing Facility 1 (CPF‐1), and source water well (1C‐501).
Injection and production performance in the West Sak Oil Pool is challenged by matrix bypass events (MBEs) or highly
conductive conduits between an injector and a producer. These conduits effectively short‐circuit the waterflood
resulting in poor pattern sweep without remediation. During 2023, four new MBE developed in the patterns 1E‐
102/1E‐121, 1J‐102/1J‐159, 1E‐105/1E‐168, and 1E‐105/1E‐123.
During 2023, five MBE remediation treatments were attempted in injectors (1J‐170, 1J‐102 (twice), 1E‐102, and 1J‐
164) to reestablish water injection support and pattern sweep. All these treatments are gel jobs pumped to remediate
their respective MBEs. The status of these treatments remains under evaluation.
In 2014, the AOGCC approved Viscosity Reducing Water‐Alternating Gas (VRWAG) injection as an enhanced oil
recovery process for the West Sak Oil Pool. There are no current plans to inject gas in West Sak due to lack of miscible
injectant in the field.
