Kuparuk River Oil Pool
2020 Annual Reservoir Surveillance Report
Summary of the Enhanced Recovery Project
Enhanced Recovery
Miscible water‐alternating‐gas (MWAG) was the main enhanced oil recovery (EOR) process for the Kuparuk Field
in 2020. In September of 2018, NGL imports from Prudhoe Bay (PBU) were brought back into Kuparuk for the first
time since 2014 and continued through 2020. Kuparuk was mainly on field‐wide MI throughout 2020 with limited
lean gas injection at CPF 1 and CPF 3 due to facility constraints. In total, 71 injectors and 24 drillsites received
miscible injectant between January and December of 2020.
Kuparuk Field manufactures miscible injectant at two of its Central Processing Facilities (CPFs). Miscible injectant
(MI) is manufactured by blending together produced lean gas (LG) and natural gas liquids (NGLs). Both indigenous
and imported Prudhoe Bay NGLs were used for enhanced recovery programs in 2020.
MWAG
Small‐Scale EOR (SSEOR and SSEORX)
Drillsites 1A, 1Y, and 2Z all received MI periodically throughout 2020. The combined 12‐month average MI
injection rate was 8.0 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, 2G 2H, 2K, 2M, 2T and 3F received MI in 2020. The combined 12‐month
average MI injection rate was 24.2 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, 3B, 3G, 3O, and 3Q received MI in 2020. The
combined 12‐month average MI injection rate was 33.6 mmscf/d.
IWAG
Minimal volumes of lean gas available after blending MI were injected into the field as immiscible water‐
alternating‐gas (IWAG) periodically throughout 2020. Drillsites 1A, 3F, and 3G received lean gas in 2020. The
combined 12‐month average LG injection rate was 1.9 mmscf/d.

Miscible Injectant Composition
Miscible Injectant (MI) 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 to ensure that
the MI meets the design Minimum Miscible Pressure (MMP). Detailed compositional analyses and MMP
(target of 3300 psia) of the MI from each CPF is provided in tabular form below. A lower MMP implies a higher
NGL content in the MI.

Meltwater Oil Pool
2020 Annual Reservoir Surveillance Report
Summary of EOR Project and Reservoir Management Summary
Background
In 2001, ConocoPhillips Alaska, Inc. (CPAI) received approvals for formation of the Meltwater Oil Pool in the
Kuparuk River Unit, an Area Injection Order for Meltwater, expansion of the Kuparuk River Unit, and
formation of the Meltwater Participating Area. The Meltwater Pool Rules and Area Injection Order were
approved on August 1, 2001. The Unit Expansion and Participating area were approved effective June 1,
2001. The Area Injection Order was modified on January 29, 2013 and again on October 8, 2015.
Miscible gas injection (MI) began in January 2002 and the miscible water-alternating gas (MWAG) process
was implemented in May 2003. The Meltwater MWAG process used Kuparuk spec miscible injectant (MI). In
2009, the water injection line to Meltwater was proactively shut-in due to internal corrosion and the field
was converted to MI flood only. In July 2014, natural gas liquids (NGLs) imported from the Prudhoe Bay Field
Central Gas Facility into the Greater Kuparuk Area ceased and the Meltwater field was subsequently
converted to lean gas injection (LGI) only.
In September 2018, NGL imports resumed and the field was returned to miscible injectant (MI) flood only
after the first phase of injection line work was completed in November 2018. This period of MI continued
until August 2019, after which the injection line was fully converted to water injection, which is the service
expected for the remainder of the field life.
The Meltwater field currently has 19 total wells (11 producers and 8 injectors). See Attachment 9 for well
locations.
Progress of EOR Project
Development activities in 2020 followed the plans described in the Pool Rules, Area Injection Order, Unit
Expansion, and Participating Area (PA) applications. Below is a listing of the key events related to the
Meltwater Pool and PA in 2020:
1. As of December 31, 2020, a total of eight producers were shut in at Meltwater (2P-415, 2P-422,
2P-424, 2P-431, 2P-443, 2P-448, 2P-449, and 2P-451) and five injectors (2P-427, 2P-429, 2P-432,
2P-438 and 2P-447). The producers are shut in for high GORs and/or low productivity and the
injectors are shut in for inability to inject below the maximum allowed sandface pressure. Two
injectors (2P-419 and 2P-447) are shut in for pressure fall off tests to better understand near
wellbore reservoir characteristics. 2P-449 failed a TIFL test and will be kept shut in until the
annular communication issue has been resolved.
2. Two producers (2P-406 and 2P-443) were converted to jet pump operations. 2P-406 has
continued to produce continuously after the conversion, whereas 2P-443 had to be shut down
due to low productivity. All other producers in Meltwater continue to be operated without any
artificial lift mechanism.
GKA Annual Surveillance Report Meltwater Oil Pool 67
Reservoir Management Summary
Meltwater came on-line in November of 2001 and has cumulatively produced 20.2 million barrels of oil
(MMBO), 3.7 million barrels of water (MMBW), and 68.4 billion standard cubic feet (BSCF) of gas by year-
end 2020. MI injection began in 2002 with water injection beginning in 2003 (MWAG cycles). Cumulative
injection through year-end 2020 at Meltwater was 27.3 MMBW and 91.4 BSCF of gas (59.1 BSCF of MI and
32.3 BSCF of lean gas). Water injection ceased in October 2009 when the water injection line had to be
taken out of service due to operational constraints caused by areas of excessive under-deposit corrosion
pitting. A gas only flood leads to increasing GORs and made the wells uneconomic to produce. Therefore,
CPAI converted Meltwater back to water injection. Currently all the injectors are being operated below the
sandface injection pressure of 3400 psi required by AIO21C. Due to the lower mobility of water in the
reservoir, combined with sandface pressure limitations, overall injection rate of water and voidage
replacement has been challenging. Several of the injectors had to be shut-in due to their inability to inject
below the maximum allowable sandface pressure. The producers were on gas lift before the water injection
conversion. After the conversion, there is no longer any gas available at the drillsite. To maintain
production, the plan is for producers to be converted to surface fluid powered jet pump as the artificial lift
method.
Cumulative I/W at Meltwater as of 12/31/2020 was 1.2. Instantaneous I/W’s varied throughout the year
depending on which injectors or producers were on. Average I/W in 2020 was 0.56 calculated based on total
injected and produced volumes in the year from Meltwater. The long-term strategy is to operate at an
instantaneous I/W of 1.0, however the primary control of water injection rate is the 3,400 psi injection
pressure limit.
Monthly I/W cumulative and rate are shown in Table 1-1 to satisfy AIO21C Rule 9 Item B: ‘reservoir voidage
balance by month of produced and injected fluids’.

Re: Meltwater Oil Pool – Proposed Pressure Survey Plan for 2021
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 2021.
Seven pressure surveys were reported for the Meltwater Oil Pool to the AOGCC in 2020. In 2020, reservoir pressures
were measured by shutting in the wells and using downhole gauges for pressure measurement.
In 2021, we expect to conduct approximately three pressure surveys.
If you have any questions concerning this data, please contact Jeff Stine at (907) 263-4735.

Results of Well Allocation, Test Evaluation, and Special Monitoring
Well Allocation
Meltwater drillsite 2P facilities were fabricated with a conventional test separator. Test separator backpressure
corrections were applied to wells that experienced greater than 100 psi backpressure over header pressure.
Correction to stock tank barrel conditions were made by applying Meltwater specific pressure corrections, derived
from the PVT analysis of Meltwater North #1 crude oil samples, and API temperature corrections.
Miscible gas was used for injection and gas lift at drillsite 2P through July 2014. From July 2014 forward, lean gas was
used for injection and gas lift until November 2018 when NGL imports resumed and the drillsite was converted back
to miscible gas. From August 2019, gas injection stopped and the drillsite was converted to water injection.
Production volumes were tracked through an automated production monitoring SCADA system (IP.21) utilizing
meters that transmit data in real-time for monitoring. The 2020 Meltwater allocation factors by month are listed
below.

Shallow Gas Special Monitoring
Wells 2P-406, 2P-417, 2P-431, 2P-432, 2P-434, 2P-438, 2P-441, 2P-447, 2P-448A and 2P-451 have a history of
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 2020. 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.
The OA pressure of 2P-432 is also being monitored to understand the dynamics of pressure charging the OA.
2020 IA and OA pressure trends for all wells are included in Attachment 7.
GKA Annual Surveillance Report Meltwater Oil Pool 78
Significant Studies in Progress
This section is meant to include the documentation to satisfy Rule 9 Item E ‘assessment of fracture propagation into
adjacent confining intervals’.
1. No new studies on the fracture propagation into adjacent confining intervals has been completed that
has not previously been reported to the AOGCC.
2. A new Meltwater reservoir management plan was put in place in July 2012 and continued to serve as the
reservoir management strategy through 2020. This reservoir strategy included imposing a well head
injection pressure limit on Meltwater injectors. The sandface injection pressure limit of 3,400 psi imposed
on Meltwater injectors is predicated upon FIT/LOT (Formation Integrity Test / Leak-off Test) data
obtained from Meltwater wells with production casing set at the top of the Bermuda interval. Since
implementing the reservoir management strategy changes, production and reservoir data continue to be
collected and shared with the AOGCC.
The overall pressure decrease from the aforementioned bleed campaign is significant, as the OA pressures of all
wells, with the exception of 2P-447, 2P-432 and 2P-431, are below the new maximum allowable operating pressure
of 1,000 psi per Area Injection Order 21C. There was indication of OA charging in 2P-432 which required pressure to
be bled off from the OA. Currently, a study is on-going to understand the source of the OA pressure in 2P-432. The
wells 2P-447 and -431 have waivers from AOGCC for higher OA pressure limit. During 2013-2018, all Meltwater outer
annuli were part of the semi-annual bleed project that was conducted as a method to monitor the change in recharge
rate over time. Each OA was bled semi-annually with the criteria of either a 4 hour maximum bleed, fluid returns at
surface, or pressure reduction to 50 psi.

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
The field is currently under evaluation to assess its future operability and profitability.
Pipeline Operations
The DS2P water injection line (2PWI) remains out of service after extensive pitting damage was discovered
throughout the line in 2009 by ILI tools. Detailed analysis of ILI and physical inspection data confirms that this
line is suitable for PO service. The current DS2P produced oil line has a low average velocity and is monitored
closely via several physical inspection locations. The 2PWI line will serve as a backup in the event the current
PO line is taken out of service.
The GI line has been converted to PWI line. A jumper was placed at DS2N to connect the water injection
source at 2N to the gas injection pipeline. The water was then transferred to the original water injection
header at DS2P for injection into the reservoir. In addition, a stream of water is being recycled directly from
the injection line to the production line to keep the production line warm during winter months as
production rates from Meltwater decline. An ILI inspection of the GI line (now in water service) has been
planned in 2021.
Exploration/Delineation
No further exploration work is currently planned for the Bermuda interval.
Surveillance plans for 2021
In accordance with AIO21C Rule 9 Item I the following bullets are key to 2021 reservoir surveillance plans.
Always keep reservoir injection pressures below 3,400 psi.
Continuous monitoring of OA pressures through the SCADA system and bleed as necessary.
Monitoring of the 2P-431 bleed system.
Periodically, evaluate reservoir pressure from injector pressure buildups/falloffs.
Collect producer shut in bottom hole pressures.

Tabasco Oil Pool
2020 Annual Reservoir Surveillance Report
Summary of the Enhanced Recovery Project
Tabasco produced 405.1 thousand barrels (MSTB) of oil, 53 million standard cubic feet (MMSCF) of gas and 5.4
million barrels of water (MMBW) during 2020. Water injection was 5.2 MMBW over the same period. Cumulative
oil, gas, and water production through year‐end 2020 were 21.5 million barrels of oil, 3.6 billion standard cubic
feet of gas, and 113.8 MMBW, respectively. Cumulative water injection through year‐end 2020 was 123.9
MMBW. The cumulative year‐end 2020 injection‐withdrawal ratio, based on current formation volume factors, is
estimated at 0.90 for Tabasco.
Year‐end 2020 Tabasco well count (Kuparuk River Unit drillsite 2T) was:
Producers: 9 completed 5 online
Injectors: 3 completed 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, 2020, Tabasco oil pool was producing with five producers and two injectors online. One of the
injectors was shut‐in due to high shut‐in bottomhole pressure measured in the well.
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 2020
production allocation factors were as follows:

2020 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 2020 injection strategy continued replacing voidage by splitting water
injection between three injectors: 2T-201, 2T-209, 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 2020. 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.
No additional development drilling wells are planned at this time.

2020 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.
Since September 2018, NGL imports from Prudhoe have resumed, thereby enabling the MWAG process to return
to Tarn.
Reservoir Management Summary
In 2020, Tarn produced 2.2 million barrels of oil, 6.9 million barrels of water (MMBW), and 2.5 billion standard
cubic feet (BSCF) of gas. The injection totals for 2020 were 0 BSCF Lean Gas, 3.7 BSCF MI, and 8.2 MMBW. At the
end of 2020, the cumulative injection/withdrawal ratio for Tarn was 1.15. Plans are to continue maintaining
reservoir pressure by balancing monthly production and injection rates.

Re: Tarn Oil Pool – Proposed Pressure Survey Plan for 2021
Dear Commissioner Chmielowski,
In compliance with Rule 8, Conservation Order No. 430A, ConocoPhillips Alaska, Inc., operator of the Tarn Oil Pool,
is hereby submitting the proposed pressure survey plan for 2021.
There were 16 pressure surveys reported for the Tarn Oil Pool to the AOGCC in 2020.
In 2021, we expect to conduct approximately six pressure surveys, including initial surveys for new wells prior to
initial sustained production or injection.
If you have any questions concerning this data, please contact Jeff Stine at (907) 263-4735.

Results of Well Allocation
Production volumes were tracked through an automated production monitoring SCADA system (IP.21) utilizing
meters that transmit data in real-time for monitoring. The 2020 Tarn allocation factors by month are listed
below. During the majority of the year, the drillsite 2L test separator gas measurement system was down. The
oil and water measurements in the test separator were functioning normally. The gas measurement system
has been fixed and is now fully functioning.

Development Plan and Operational Review
Development Drilling
No development wells were drilled at Tarn in 2020.
Producer to Injector Conversions
No well service conversion projects were executed in Tarn in 2020.
Artificial Lift
Tarn was originally designed to use miscible gas injection as a means of gas lifting the production wells.
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.

Attachment 1
West Sak Oil Pool
2020 Annual Reservoir Surveillance Report
Summary of the Enhanced Oil Recovery Project
During 2020, there were 56 active producers and 63 active injectors, including 6 water‐alternating‐gas injectors and
57 water 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) and Central
Processing Facility 1 (CPF‐1).
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 2020, one new MBE developed between the 1E‐102 and
1E‐121 while the 1E‐121 was shut‐in.
During 2020, two MBE remediation treatments were attempted in injectors 1C‐190 and 1J‐105 to reestablish water
injection support and pattern sweep. 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. Injectors 1C‐150, 1C‐152, 1C‐154, 1D‐142, 1H‐119, and 1J‐118 received
VRI injection during 2020. Early results of VRWAG suggest positive benefits and pattern‐level surveillance efforts
continue.

Re: 2020 Allowable Gas Offtake from Kuparuk River Oil Pool
Dear Commissioner Chmielowski,
In compliance with Rule 13, Conservation Order No. 432D, ConocoPhillips Alaska, Inc., operator of the Kuparuk River
Oil Pool, is hereby submitting the gas offtake volume information for 2020 (Attachment 1).
During 2020, the annualized average gas offtake was 2,267 MSCFD, considerably less than the maximum allowable
annual average gas offtake rate of 5,000 MSCFD as stated in Rule 13 for Kuparuk River Oil Pool.
The low annualized average gas offtake was driven by Oooguruk’s gas production, which exceeds their injection and
fuel consumption, resulting in taking only their return gas and no makeup for fuel.
If you have any questions concerning this data, please contact Jeff Stine at (907) 263-4735.
Sincerely,
Carlotta Chernoff
