GKA Surveillance Report 10 Attachment 1 Kuparuk River Oil Pool 2024 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 2024. In September 2018, NGL imports from Prudhoe Bay (PBU) were brought back into Kuparuk for the first time since 2014 and continued until September 2021. With the cessation of Prudhoe Bay NGL imports in 2021, only Kuparuk indigenous NGLs were blended for gas enrichment in 2024. In total, 77 injectors and 20 drillsites in the Kuparuk Field received enriched gas injectant between January and December 2024. Kuparuk Field manufactures enriched gas injectant at two of its Central Processing Facilities (CPFs). Enriched gas injectant is manufactured by blending produced lean gas (LG) with indigenous natural gas liquids (NGLs). The NGL pump at CPF1 was out of continuous service from October 2023 through October 2024. During this period, 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. All three received EWAG periodically throughout 2024. The combined 12-month average enriched gas injection rate was 3.8 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, 2M, 2T, and 3F received enriched gas in 2024. The combined 12-month average enriched gas injection rate was 40.2 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, 3G, and 3Q received enriched gas in 2024. The combined 12-month average MI injection rate was 65.9 MMSCF/d. IWAG Minimal volumes of lean gas available after blending enriched gas were injected into the field as immiscible water- alternating-gas (IWAG) periodically throughout 2024. Drillsites 2A, 2B, 2Z, 3B, and 3F received lean gas in 2024. The combined 12-month average LG injection rate was 2.4 MMSCF/d.

There were thirty-one injection surveys reported for the Kuparuk River Oil Pool to the AOGCC in 2024 (Attachment 5). In 2025, 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 thirty-two production surveys conducted in 2024. If you have any questions concerning this data, please contact Adam Schnellbaecher at (907) 263-4188.

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. GKA Surveillance Report 62 Attachment 8 Kuparuk River Oil Pool 2024 Annual Reservoir Surveillance Report LSEOR Development Plan During 2024, the Greater Kuparuk Area (GKA) averaged 7,401 BPD of indigenous NGLs distributed amongst an annual average of 153 million standard cubic feet per day (MMSCFD) of variably enriched injectant manufactured, 119.8 MMSCFD of which was used for downhole injection for tertiary recovery. NGL imports from Prudhoe Bay ceased in September of 2021. The calculation of total injectant manufactured rate was achieved differently than in previous years. Due to the NGL pump at CPF1 being out of continuous service through October 2024, one of the meters used to measure injectant manufacturing rates was bypassed along with the NGL skid. Thus, instead of using the NGL skid output for the total injectant manufactured rates, the total sum of all enriched gas injection and enriched gas lift is provided. Of the total enriched gas production in 2024, 109.9 MMSCFD was injected into the main Kuparuk Field. Within the main Kuparuk Field, 3.8 MMSCFD was allocated for SSEOR and SSEORX, and 106.1 MMSCFD was allocated for the LSEOR and LSEORX expansion which included drillsites 1F, 1Q, 2A, 2B, 2C, 2H, 2M, 2T, 3F, 1B, 1C, 1D, 1E, 1L, 2S, 3G, and 3Q.

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 2024. 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. 2024 IA and OA pressure trends for all wells are included in Attachment 7. GKA Surveillance Report 77 Attachment 7 Meltwater Oil Pool 2024 Annual Reservoir Surveillance Report 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. P&A preparation work was ongoing throughout 2024, and 2P- 420 P&A was completed in 2024.

Pipeline Operations Currently all pipelines to and from 2P drillsite have been temporarily abandoned in place and final abandonment was executed in 2022 summer. Exploration/Delineation No further exploration work is currently planned for the Bermuda interval.

GKA Surveillance Report 95 Attachment 1 Tabasco Oil Pool 2024 Annual Reservoir Surveillance Report Summary of the Enhanced Recovery Project Tabasco produced 396 thousand barrels (MSTB) of oil, 80 million standard cubic feet (MMSCF) of gas and 6.53 million barrels of water (MMBW) during 2024. Water injection was 6.2 MMBW over the same period. Cumulative oil, gas, and water production through year‐end 2023 were 23.1 million barrels of oil, 3.83 billion standard cubic feet of gas, and 137.2 MMBW of water, respectively. Cumulative water injection through year-end 2023 was 146.6 MMBW. The cumulative year‐end 2024 injection-withdrawal ratio, based on current formation volume factors, is estimated at 0.90 for Tabasco. Year‐end 2024 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, 2024, Tabasco oil pool was producing with five producers and two injectors online. 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.

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 2024 production allocation factors were as follows: Month Oil Gas Water Jan-24 0.9278 0.8206 1.0277 Feb-24 0.9079 0.8201 1.0234 Mar-24 0.8896 0.8180 1.0137 Apr-24 0.8829 0.8160 1.0275 May-24 0.8793 0.9269 1.0302 Jun-24 0.8249 0.7831 1.0401 Jul-24 0.8110 0.8629 1.0459 Aug-24 0.8563 0.8803 1.0193 Sep-24 0.8706 0.8782 1.0263 Oct-24 0.8860 0.8668 1.0346 Nov-24 0.8588 0.8487 1.0206 Dec-24 0.8437 0.8775 1.0166 GKA Surveillance Report 106 Attachment 7 Tabasco Oil Pool 2024 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 2024 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 2024. 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 improving overall oil recovery. In 2024 the producers 2T-215 and 2T-203 were worked over to replace broken ESP’s. No additional development drilling wells are planned at this time. GKA Surveillance Report 107 Page left blank intentionally.

GKA Surveillance Report 112 Attachment 1 Tarn Oil Pool 2024 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 2024, Tarn produced 1.43 million barrels of oil, 3.12 million barrels of water (MMBW), and 2.88 billion standard cubic feet (BSCF) of gas. The injection totals for 2023 were 3.63 BSCF enriched gas, and 4.43 MMBW. At the end of 2024, the cumulative injection/withdrawal ratio for Tarn was 1.15. Plans are to continue maintaining reservoir pressure by balancing monthly production and injection rates.

Producer to Injector Conversions No well service conversion projects were executed in Tarn in 2024. 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). Three wells (2L- 304, 2N-315, and 2N-309) are in the plans for a rig workover. GKA Surveillance Report 122 GKA Surveillance Report 123 Page left blank intentionally.

Sincerely, Donald Allan Manager, GKA Asset Development Greater Kuparuk Area GKA Surveillance Report 170 GKA Surveillance Report 171 Attachment 1 West Sak Oil Pool 2024 Annual Reservoir Surveillance Report Summary of the Enhanced Oil Recovery Project During 2024, there were 54 active producers and 57 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 2024, one new MBE developed in the 1H‐115/1H‐104 pattern. During 2024, two MBE remediation treatments were attempted in injectors (1J‐102, 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.
