GKA Annual Surveillance Report Kuparuk Oil Pool 11 Attachment 1 Kuparuk River Oil Pool 2022 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 2022. 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 2022. In total, 65 injectors and 23 drillsites in the Kuparuk Field received enriched gas injectant between January and December of 2022. 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). EWAG Small-Scale EOR (SSEOR and SSEORX) Drillsites 1A, 1Y, and 2Z all received EWAG periodically throughout 2022. The combined 12-month average enriched gas injection rate was 5.6 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, 2G, 2H, 2K, 2M, 2T, and 3F received MI in 2022. The combined 12-month average enriched gas injection rate was 22.4 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, 2S, 3G, 3O, 3Q and 3S received enriched gas in 2022. The combined 12-month average MI injection rate was 50.8 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 2022. Drillsites 1C, 1F, and 2S received lean gas in 2022. The combined 12-month average LG injection rate was 0.7 mmscf/d.

There were six injection surveys reported for the Kuparuk River Oil Pool to the AOGCC in 2022 (Attachment 5). In 2023, 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 two production surveys conducted in 2022. 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. 74 GKA Annual Surveillance Report Kuparuk Oil Pool GKA Annual Surveillance Report Kuparuk Oil Pool 75 Attachment 8 Kuparuk River Oil Pool 2022 Annual Reservoir Surveillance Report LSEOR Development Plan During 2022, the Greater Kuparuk Area (GKA) averaged 7,307 BPD of indigenous NGLs for an annual average of 103 million standard cubic feet per day (MMSCFD) of enriched injectant manufactured, 92.1 MMSCFD of which was used for downhole injection for tertiary recovery. NGL imports from Prudhoe Bay ceased in August of 2021. Of the total enriched gas production in 2022, 78.8 MMSCFD was injected into the main Kuparuk Field. Within the main Kuparuk Field, 5.6 MMSCFD was allocated for SSEOR and SSEROX, and 73.2 MMSCFD was allocated for the LSEOR and LSEORX expansion which included drillsites 1F, 1Q, 2A, 2B, 2C, 2G 2H, 2K, 2M, 2T, 3F, 1B, 1C, 1D, 1E, 1L, 2S, 3B, 3G, 3O, 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 2022. 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. 2022 IA and OA pressure trends for all wells are included in Attachment 7.

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.

GKA Annual Surveillance Report Tabasco Oil Pool 107 Attachment 1 Tabasco Oil Pool 2022 Annual Reservoir Surveillance Report Summary of the Enhanced Recovery Project Tabasco produced 441 thousand barrels (MSTB) of oil, 60 million standard cubic feet (MMSCF) of gas and 5.85 million barrels of water (MMBW) during 2022. Water injection was 5.6 MMBW over the same period. Cumulative oil, gas, and water production through year-end 2022 were 22.3 million barrels of oil, 3.67 billion standard cubic feet of gas, and 125.5 MMBW of water, respectively. Cumulative water injection through year-end 2022 was 135.4 MMBW. The cumulative year-end 2022 injection-withdrawal ratio, based on current formation volume factors, is estimated at 0.90 for Tabasco. Year-end 2022 Tabasco well count (Kuparuk River Unit drillsite 2T) was: Producers: Injectors: 9 completed 3 completed 5 online 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, 2022, 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.

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 2022 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 2022. The reservoir management strategy is predicated upon injecting water deep into the central canyon and produce from the periphery. 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 its 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.

GKA Annual Surveillance Report Tarn Oil Pool 124 Attachment 1 Tarn Oil Pool 2022 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; however CPF2 continued to blend gas in a configuration that has allowed MI to be sent to Tarn for injection purposes. Reservoir Management Summary In 2022, Tarn produced 1.48 million barrels of oil, 2.8 million barrels of water (MMBW), and 2.53 billion standard cubic feet (BSCF) of gas. The injection totals for 2022 were 0 BSCF Lean Gas, 4.67 BSCF MI, and 4.69 MMBW. At the end of 2022, 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 2022. 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 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. The measurements improved after a cleanout of the accuflow, 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 have been addressed. However at least four wells (2L-321, 2L-326, 2N-316 and 2N-315) are in the plans for a rig workover.

GKA Annual Surveillance Report West Sak Oil Pool 163 Attachment 1 West Sak Oil Pool 2022 Annual Reservoir Surveillance Report Summary of the Enhanced Oil Recovery Project During 2022, there were 56 active producers and 62 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) 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 2022, two new MBE developed in the patterns 1J- 102/1J-159 and 1J-170/1J-166. During 2022, three MBE remediation treatments were attempted in injectors 1C-127, 1J-136, and 1E-102 to reestablish water injection support and pattern sweep. All of these treatments are gel jobs pumped to remediate their respective MBE’s. 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. In 2022 gas was injected only in 1C-154. There are no further plans to inject gas in West Sak due to lack of miscible injectant in the field. Lean gas injection leads to rapid breakthrough of gas in West Sak which leads to enhanced sand production and subsequent MBE’s.
