Attach Stratigraphic Column separately.): Summary of Pnposed Injection Program KMOG proposes a project to implement enhanced oil recovery in the Denver-Julesburg Basin ("DJ Basin") of Colorado through "huff and puff' style operations. Huff and puff operations involve cyclic hydrocarbon gas injection with the potential to be supplemented by water and surfactant injection as necessary into a compatible formation. Using an existing producing well as an injector, hydrocarbon gas is injected downlmle at high pressure during the "puff" cycle. The gas contacts the oil and through a process called diffusion, it soaks into the oil at a pressure exceeding the minimum miscibility pressure (which is the pressure at which the gas and oil are converted into a homogeneous phase). The injected hydrocarbon gas changes the oil viscosity, interfacial tension, and relative permeability by swelling the oil. The injector is converted back to a producer during the "huff" cycle where the oil flows back and is produced from the wellbore. Once an injector is converted back to a producing well, gas injection will occur in a subsequent well within the Griswold EOR Unit. The huff and puff injection/soak/production cycles will be repeated and optimized in terms of duration and slug size to determine when the producing well will be returned to injection. This process will be repeated for each well within the Griswold EOR Unit until there are diminished returns. The Griswold FOR Unit will include six (6) horizontal wells to be used as alternating injection and production wells and two (2) horizontal production wells to be used as operational support wells. The alternating injection and production wells are on the Griswold 27N-11 HZ Location, and the two operational support wells are on the Griswold 29N-11 HZ location. All planned injection operations will oocur at the Griswold 27N-11 HZ Location. The Griswold 29N-11 HZ Location will only be utilized for operational support and monitoring purposes. Operational support operations may require the use of these wells for the benefit of the Proposed Injection Wells through the establishment of a water curtain. Accordingly, the Operational Support Wells are included as Proposed Unit Wells for purposes of the allocation of production. However, no gas injection operations will be conducted from the Griswold 29N-1-1HZ Location. Geologic Formation Summary Please reference the attached Stratigraphic Column (doc #403491257) for information complying with the requirements of Rule 803.g. (5).B. including injection and confining layers, sources of USDWs, and hydrocarbon -bearing layers. Injected Water & Gas Analysis Water Sample & Analysis Source: The injected freshwater analysis was conducted by SGS North America Inc. and GEL Laboratories, LLC. The sample was obtained from the Beebe Seep freshwater source on June 5, 2023 and is representative of freshwater that will be used for injection during the Griswold EOR pilot project. All samples were extracted within the recommended method holding time, and all method blanks for this batch met method specific criteria. Gas Sample & Analysis Source: A gas analysis was conducted by EMPACT Analytical Systems Inc. The sample was collected on June 19, 2023 from the Fort Lupton Gas Plant to be used for injection. Surfactant Details: Surfactant will only be used on an as needed and temporary basis. The surfactant is not a commercial product yet and the composition is a DOW trade secret, so the full chemical composition is unavailable. Injected Zone Analysis Laboratory analytical results have been taken from a representative water sample collected from the Verde 13-3HZ Tank Battery, location ID 453358 on June 5, 2023. The Injected Zone Analyses comply with the requirements of Rule 803.g.(5).D. The TDS of all injected zone formations are over 10,000 mg/L per the samples provided, therefore no Aquifer Exemption is necessary. Additionally, a TDS greater than 10,000 mg/L is confirmed by the Water Petrophysical Analysis. Date Run: 8/17/2023 Doc M4033896051 Page 1 of 5 Compatibility of the Injection Fluid with the Injection Zone The primary injectant for the proposed formations is hydrocarbon gas, which has a composition similar to what has been previously produced from the proposed Griswold EOR Unit. There should be no compatibility concerns because the injected fluid originated from the same formations or formations with similar enough composition as will be injected into. Additionally, water may be injected into the injection well and/or adjacent wellbores to act as a pressure barrier to help contain the injected gas proximate to the injection wellbore. There is no anticipated effect to the formation anticipated from the water filling the pores between the grains. Surfactant may be injected to help with gas conformance and containment to help the formation reach the minimum miscibility pressure. Fluid/Gas Source and Transport Method The source of the hydrocarbon gas will be from the Fort Lupton Gas Plant via carbon steel pipe. Source gas will be delivered from a custody transfer point north of the facility and brought to location through a dedicated gas line. This is the only source of produced gas going to the Griswold EOR Unit. This addresses Rule 803.g. The fresh water will be sourced from one of the following locations: Poudre River, Hillsboro Ditch, Greeley Loveland Ditch, New Thomas Reservoir, Beebe Seep, Gobbler Pit, Mayer Well, Milton Reservoir, Prospect Valley Pump Station, Signal 2 Reservoir and the Platte River. The fresh water will be transferred through the existing Water On Demand pipeline system to a hydrant near the Griswold 27N-11 HZ Location. From there a temporary lay -flat piping will be connected to transport the water from the hydrant to the pad location. This will nearly eliminate truck traffic associated with water injection. Surface Facilities, Separation & Treatment Process Surface facilities include enclosed flares, a flare knockout drum, an ECD blowcase, instrument air skids, a compressor cooler, an injection compressor, a bulk condensate separator, an inlet filter separator, a methanol injection skid, a pressure let down skid and an electric line heater. The injection gas is received through an inlet filter where contaminants, liquids, and other impurities are removed. The gas is then compressed to the injection pressure, with forced draft gas coolers utilized between compression stages to lower the operating temperature of the gas. The high-pressure injection gas is routed through an injection manifold to be diverted to the selected injection well(s). Produced fluid is brought back to the facility through a pressure letdown skid where the working pressure is reduced. A process heater is used` between pressure reduction stages to maintain the desired operating temperature of the fluid. The produced fluid is then routed through a condensate separator where the product is split between gas and liquid streams, each of which is routed independently to the existing surface location through dedicated pipelines. Surfactant injection equipment may also be used to aid in well conformance. This is achieved by running a low concentration surfactant solution through a high-pressure water pump and utilizing the injection manifold to divert the solution to the selected well(s). If surfactant injection is used, 500 bbl water storage tanks, a chemical tote, an electrical chemical pump, piping/valve manifold skids and water injection pump will be added to the location. Process Flow Diagrams and the Surface Facility Diagram show detail regarding the surface facilities and injection and flowback processes. Injection Volume, Pressures and Fracture Gradient The estimated volurne of gas to be injected daily ranges from 1-20,000 mcf/day per well at an anticipated injection pressure of 0-5000 psi. The estimated volume of fresh water to be injected daily ranges from 1-2000 bbl/day per well at an anticipated injection pressure of 0 -2500 psi. This represents the range of pressures and rates at the faciity but will match the individual well rates initially as the pilot project begins with single well injection. The fracture gradient is 0.92 psi/ft for the Codell, 0.96 psi/ft for the Carlile, 0.90 psi/ft for the Ft Hays and 0.82 psi/ft for the Niobrara formation.

PREPARED Kerr-McGee FOR: oil & Gas Onshore � P Doc number 403452228 Petrophysical Analysis of Niobrara and Codell Formation Waters Prepared by Amber Peterson, Oxy Petrophysical Advisor Porosity -Resistivity Pickett plots show approximately 25-50% water saturation in Niobrara and Ft Hays, and 50-75% in the Carlile, at 50,200 ppm NaCI formation water salinity, consistent with core analysis. The Codell shows approximately 50-75% water saturation on the Pickett plot, but in reality has lower water saturation which implies excess conductivity. The assumption for the Codell is that the formation water salinity remains the same, but the best saturation model is a Waxman-Smits model and is therefore not reflected in the standard Pickett plot. A standard Pickett plot interpretation would increase the formation water salinity in the Codell to N171,000ppm NaCI. • 6 wells reviewed • Tied to closest core: Thermo 38N -33H (13,841 ft away from Unit) • Closest petrophysical model well: Amato 22-1 (5,426 ft away from Unit) Figure 1: Location Map Li i_ t lone t Steve Sharp 9 70 Crane & Rigging Certarus 9 Thermo;38N=33HZ• Ei Coyote Creek Golf Course Fort Lupton • Wallenberg, 41:4 1W a Brighton e • 0 Eli Eli Aristocrat anchettes Ell ES Platte Valley Airpark 4 Amato122=11 a 4 • Proposed Unit isaj Section 11 Eil I m m Asphalt By Chavez 9 Johnson Farm and Apiary ? ern�+.�r►ty r.

The Denver-Julesberg basin is an asymmetrical Laramide aged basin elongated North to South (Exhibit 1). It is bound by the front range of the Rocky Mountains to the west on its steeply dipping limb with a gradually dipping eastern limb stretching nearly to the Kansas border. To the north it is bound by the Hartville Uplift in Wyoming and to the south by the Apishapa uplift and Las Animas Arch (Drake II, R.M. et al. 2012). EOR injection followed by production is planned into the Cretaceous aged Niobrara chalk formation (82-87Ma) at this location. The structural setting during the time of Niobrara deposition was a foreland basin associated with the Sevier Orogeny. During this time, a shallow seaway existed connecting the Gulf of Mexico to the Arctic Ocean commonly referred to as the Western Interior Seaway (Longman, 2020). Oxy has evaluated both the local and regional risks for the potential of inducing seismicity with this project and has concluded the risk to be low. Below are comments on the figures included in this evaluation that assist in this determination. Exhibit 1: The Griswold EOR Unit sits above granitic basement rocks of Paleoproterozoic age shown in a light orange color on the map derived from aeromagnetic data interpretation (Sims, P.K., et al, 2001). The world stress data overlain on this map shows the current maximum stress state in this area to be NNW -SSE (httn://www.world-stress-mas.ore/). The current tectonic stresses are extensional in nature as the North American Plate moves away from the Pacific Plate (Meldahl, 2011). Exhibit 2: Surface geology map from Tweto, 1979 shows the Griswold Unit and the 12 -mile radius sit within an area of Quaternary, Tertiary and Triassic sediments at surface. Faulting is present at surface approximately 11 miles west of the EOR injection site. Faulting further west in the Precambrian Granite formations concur with the regional uplift forming the front range of the Rocky Mountains. Exhibit 3: Within the Niobrara formation there are numerous layer bound extensional faults as shown on a 3D seismic line through the 12 -mile EOR radius. This fault system is contained within the Niobrara Formation and is not connected to the basement along this shear zone or within the 12 -mile radius surrounding the Griswold EOR Unit. These faults are considered non -tectonic in origin (Bracken, 2020). Exhibit 4: The current tectonic setting is extensional, which is accommodated in this area by a transtensional shear zone characterized by an extensional strike -slip duplex in the basement. The maximum stress runs perpendicular to the shear zone in the area therefore this fault is not critically stressed and presents a lower risk for induced seismicity Exhibit 5: There are four identified historic seismic events within the 12 -mile radius of the Griswold EOR Unit. These seismic events occurred from 1966-1967 and ranged from 3.5-5.3 magnitude. They are located in 1S66W, 2S66W, and 2S65W at a distance of approximately 8 miles from the injection location. These events have been attributed to wastewater injection directly into the Precambrian Basement at the Rocky Mountain Arsenal (Hsieh, P.A., Bredehoeft, J.D., 1981). The Griswold EOR Unit plans injection into the Niobrara formation followed by production so pressures will not remain elevated through time. This should lead to a decreased chance of induced seismicity. ku KerrNMGee Exhibit 6: The 2018 USGS Short Term Seismic Activity potential indicates that this area has less than a 1% chance of potentially minor -damage ground shaking in the Griswold EOR Unit AOI. Exhibit 7: The 2018 USGS Long Term Seismic Hazard Potential indicates that the Griswold EOR Unit AOI falls within the lower hazard categories. Exhibit 8: The Niobrara formation is approximately 3,900 feet above the Precambrian basement near to the Griswold Unit. The nearest well penetration with logs to the basement is the KMG 16-24i well drilled in 2016 approximately 9 miles to the northeast of the Griswold Unit. The large distance between the injection formation and the basement coupled with the lack of fault connection between the two units leads to a lowered risk of induced seismicity.
