Operations at the proposed drill site typically will begin with construction of the site and will include leveling the pad to accommodate the drilling rig. Once the pad construction is completed, drilling rig equipment will be brought onto location and rigged up. Drilling operations, which run twenty-four (24) hours a day until completed, will commence after the rig is "rigged up". The surface holes will be drilled to approximately 2000 feet using fresh water. Surface casing will then be run and cemented to surface to protect any shallow fresh water zones. Surface casing setting depth is determined from subsurface ground water maps prepared by the State Engineer and supplemented by the latest data available from offsetting wells. The cement is allowed to set, and well control equipment is installed and tested. After about 8 hours of waiting on cement and installing well control equipment, a drill bit is run into the hole to drill the intermediate portion of the well into the potential oil and gas bearing formations. The wells will be drilled horizontally. The wells will be turned or steered such that a curve will be drilled to approximately 90 degrees or parallel to the surface of the ground. The typical vertical depth for the wells is approximately 7,000-8,000 feet below ground level and the length of the horizontal leg will be approximately 3.0 miles long. The total Measured Depth (MD) of a typical well in this project is approximately 17,000 —20,000 feet. Once the horizontal section of the wellbore is drilled, a string of production casing will be run into the wellbore. This casing will be cemented into place to isolate the productive zones of the reservoir. Bison's drilling rigs are equipped with a closed loop system. The drilling rig will be on location for approximately six (6) days per horizontal well. At the end of the drilling phase, the drilling rig will be moved off location. The completion phase begins when the drilling equipment is transported off the location. Completion operations are conducted twenty-four (24) hours per day over a period of several weeks. The site may be bladed and leveled to accommodate the completion rig and anchors may be set for the completion rig. Additional operations including cementing, drilling and logging may occur as circumstances require. For horizontal wells, multiple fracture stages are induced along the length of the wellbore in the respective formation into which the well has been drilled. During hydraulic fracturing, water is pumped at high rates and pressures that exceed the minimum in -situ rock stresses and hydraulically fracture the formation. Sand is then pumped into the created fracture to allow gas gBisoN I3d OPERATING Bison IV Operating, LLC 51817th Street, Suite 1800 Deliver, CO 80202 Phone: 720-64-6997 Fax: 303-974-1767 and oil to flow freely from the formation into the well bore. The fracturing equipment will consist of one Modular Large Volume Tank (MLVT) for fresh water storage, multiple flowback tanks, pressure pumps, blending and bulk material trucks with other necessary equipment. After fracturing is completed the mobile equipment is removed, excluding tanks that are used to retain the water that is produced during flowback and testing operations. No water is allowed to accumulate or be disposed of on surface. All water is hauled to approved disposal sites or recycled for stimulation use. The flowback tanks will remain on location until the well is rerouted through standard production equipment. The production equipment for these wells will be located adjacent to the wells. Typical equipment will consist of oil and water tanks constructed within berms comprised of steel rings with a synthetic or engineered liner, separators, vapor recovery and emission control equipment, gas compressors, meters, flowlines, and proposed electrical and/or solar equipment. The location will include automation equipment that allows operators to remotely monitor pressures, rates, temperatures, valve positions and tank levels. Once production commences, a Bison employee or contractor will monitor the location on a regularly scheduled basis. These inspections are done as a routine part of the lease operator's job. They conduct a visual inspection of the facility which includes all valves, fittings, wellhead, tanks, vapor control systems and all connections. The lease operator reports the tank measurements of the oil, gas sales, and pressure readings. Much of this production information is compiled and submitted to the ECMC on a monthly basis. In addition, the lease operator will inspect the site for hazards and weed control, maintaining the safety and appearance of the Pads. The anticipated lifespan for the proposed well(s) is 30 years. Once a well is determined to no longer be productive and/or economic, a plugging rig will remove production equipment and plug the productive zone(s) with a combination of bridge plugs and cement plugs. Surface equipment no longer needed will be removed. Final surface restoration will involve removal of any above -ground casing and the installation of regulation markers that will not interfere with subsequent surface use. Remaining disturbance will be restored to the original grade and reseeded in compliance with ECMC and Local Government rules and regulations and in accordance with surface owner's future land use plans. The expected travel routes for the proposed oil and gas location would come from the west on State Highway 392 to the intersection of State Highway 392 & WCR 74. Traffic would then continue south approximately 1074 ft on WCR 74 and then continue east on WCR 74 for 0.8 miles to the existing access road on the north side of WCR 74. See the attached haul route map. The duration of construction, drilling, and completion activity is estimated to be between 2-4 months (see Table 1: Proposed Development Schedule below). During this "active operations" phase, vehide traffic will include passenger cars and pickups, semi-truck/trailers, and tandem truck vehides. The number of round trips per day expected for each vehicle during active operations is summarized in Table 2: Estimated Traffic during Active Operations below. The highest traffic volumes are expected during the first two days of and the last two days of both drilling and completions operations. Traffic will intentionally be highest during daylight hours to mitigate noise and dust during non -working hours. fIB'SON -77 IV OPERATING Bison IV Operating, LLC Table 1: Proposed Development Schedule 51317 u, Street, Suite 1800 Denver, CO 80202 Phone: 720-644-6997 Fax: 303-974-1,7 Phase Duration (days) +/- 30 days +/- 60 days +/- 45 days +/-10 days Ongoing +/- 30 years +/- 30 days Estimated Start Date Construction 3rd Quarter 2025 Drilling 3rd Quarter 2025 Completion 4th Quarter 2025 Flowback 1st Quarter 2026 Production 1st Quarter 2026 2"d Quarter 2026* Interim Reclamation °or the first favorable weather/growing season gBIsoN IV OPERATING Bison IV Operating, LLC 51817u, Street, Suite 1800 Denver, CO 80202 Phone: 720-644-6997 F.: 303-974-1767 Table 2: Estimated Traffic (roundtrips/day) during Active Operations for Dorado 36 (10 HZ Wells) Phase of Development # of Vehicle Roundtrips (per day) Passenger car equivalent roundtrips (per day) Construction Phase: earthwork of pad/facility & access road (30 days +/-) Passenger Vehicles111 9 Single Unit Trucks121 2 Multiple Unit Trucks131 21— 25 9 4 75 TOTAL roundtrips per day = Drilling Phase (60 -100 days +/-, ^'6 -10 days/well) Passenger Vehicles111 Single Unit Trucks1�1 Multiple UnitTrucks131 TOTAL roundtrips per day = 36 88 6 3 6 6 5 18 15 29 Completion Phase (45 days +/-, —15 days/4-well zipper frac) Passenger Vehicles111 17 Single Unit Trucks121 2 — 3 Multiple Unit Trucks131 17 - 125 141 TOTAL roundtrips per day = Flowback Phase (5 —10 days f/-) Passenger Vehicles(1) Single Unit Trucks1�1 Multiple UnitTrucks131 TOTAL roundtrips per day = Interim Reclamation (30 days +/-) Passenger Vehicles111 Single Unit Trucks(2) Multiple Unit Trucks14l TOTAL roundtrips per day = 17 5 50 — 375 36-145 72-397 5 2 3 5 4 8 10 17 5 0 0 5 0 0 5 Production/Operations Phase (ongoing for life of well, assuming facility is tied -in to distribution/collection system) Passenger Vehicles1�1 2 2 Single Unit Trucks1�1 0 0 Multiple Unit Trucks(3) 0 0 TOTAL roundtrips per day = 2 2 (1) Passenger Vehicle: <20'; gross vehicle weight: 4,500 — 8,5001bs (Source: CDOT State Highway Access Code [SHAC]) l21 Single Unit Truck: 20' — 40'; gross vehicle weight: 10,000 — 20,000 lbs; = 2 passenger car equivalents (CDOTSHAC) 134 Multiple Unit Truck: >40'; gross vehicle weight: 50,000 — 70,000 lbs; = 3 passenger car equivalents (CDOT SHAC) (�1 Multiple unit truck volume during completion phase dependent upon water transport options, i.e., temporary layflat line vs. trucking water to location.

Oil and gas operating companies ("Operators") are required to obtain approval of an Oil and Gas Development Plan ("OGDP") from the Colorado Oil and Gas Conservation Commission ("COGCC") prior to undertaking any new operations such as drilling oil and gas wells or building oil and gas locations. When an Operator submits an OGDP application to the COGCC for consideration, and the application has been received and is deemed complete, COGCC staff begins a formal technical review of the application materials, and a public comment period starts. COGCC has prepared this information sheet to inform the public of the procedural steps involved with the Director's and Commission's review of an OGDP, so that the public is informed and may participate in the review process if they choose. As part of the process, Operators must provide this information sheet to certain recipients, like yourself, that include mineral owners within the area of proposed development and all landowners, homeowners, commercial property owners, tenants, and other entities within 2,000 feet of an oil and gas location proposed by a pending OGDP application. What is an Oil and Gas Development Plan (OGDP)? An OGDP is an Operator's plan to develop oil or gas resources ("minerals") from one or more surface locations. Operators prepare an OGDP and associated application materials, consistent with the requirements of COGCC Rule 303, and submit the plan for approval through the Commission's Hearings process. The application materials include a hearing application; one or more Form 2A, Oil and Gas Location Assessments; a Form 2B, Cumulative Impacts Data Identification; and a Form 2C, OGDP Certification. The application may also include a request for the establishment of one or more Drilling and Spacing Units ("DSUs"). The OGDP, along with its associated supporting documents, will be heard at a public hearing where the Commission will make a final determination to approve or deny the OGDP application. What are the procedural steps involved with the Director's and Commission's review of Oil and Gas Development Plans? 1. OGDP application is submitted: Operator/ Applicant submits a complete OGDP application with all supporting documents. The written portion of the application is submitted to the COGCC hearings unit via the eFilings system, and Forms 2A, 2B, and 2C are submitted to technical staff via the eForms system. (See Rules 303 £t 304) 2. OGDP application is received: The COGCC hearings unit reviews the written hearing application, assigns a docket number for the OGDP, and provides public notice for the hearing. (See Rules 303 a 504) 3. Completeness determination: The COGCC technical staff and Director review the application materials for completeness. When deemed complete: a. the OGDP application materials are posted on COGCC's website; b. the Operator provides notice (including this information sheet) to relevant persons; c. the public comment period begins; d. the formal consultation period commences as applicable (including relevant/ proximate local governments and other agencies such as Colorado Parks and Wildlife ("CPW") or Colorado Department Page 2 of Public Health and Environment ("CDPHE")); and e. COGCC staff begin their technical review of the OGDP components. (See Rule 303). 4. Director's review of application (technical review): COGCC technical staff conducts the technical review of all application materials to ensure compliance with COGCC Rules, ensure the protection of public health, safety, welfare, the environment, and wildlife resources, and to evaluate potential Cumulative Impacts. The technical review includes analysis and assessment of: a. DSUs and protection of mineral owner's correlative rights; b. proposed surface locations and alternative locations; c. downhole and engineering considerations; d. best management practices; e. public comments and recommendations provided by consulting agencies; financial assurance; and the need for conditions of approval. (See Rule 306) 5. Director's recommendation: Once the Director has reviewed the application materials, the Director provides a written recommendation to the Commission in support of the approval or denial of the OGDP application. The Director will post the recommendation on COGCC's website, notify relevant parties', and submit it to the COGCC hearings unit in preparation for hearing. (See Rule 306.c) 6. Commission's consideration and final action (public hearing): The Commission receives the f. g. ' Parties who receive this information sheet will not necessarily be included in the notice of the Director's recommendation. Parties who make a public comment on the Form 2A and include their email address will receive the notice of the Director's recommendation. Director's recommendation of the OGDP and begins review of the OGDP with support from the COGCC hearings unit. The review includes all supporting documents, written testimony, public comments, consulting agency recom- mendations, and Director's recommendation. The Commission considers the OGDP at a public hearing, which may include oral testimony provided during the hearing. The Commission makes a final determination and presents its findings in a written order based on the evidence in the record; the Commission's order to approve or deny the OGDP application is final. (See Rule 307) Where can I get additional information? For more information about the COGCC administrative hearing process and OGDPs, please refer to the COGCC website at http://cogcc.state.co.us. You may also contact the COGCC at dnr.ogcc@state.co.us or 303- 894-2100. Please note, COGCC staff are not available to provide legal advice. COGCC recommends that you engage an attorney with knowledge of oil and gas matters to assist you with reviewing any offers you receive from an oil and gas operator or other person.

Why am I receiving this Information Sheet? You have received this Colorado Oil and Gas Conservation Commission ("COGCC") information sheet because an oil and gas operator ("the Operator") has submitted an application for an Oil and Gas Development Plan ("OGDP"), and that application is under review by the COGCC. Per COGCC Rule 303.e.(1), the Operator is required to provide this information to you within seven days of the application materials being posted on the COGCC website. COGCC Rule 303.d requires the COGCC to open a formal "public comment period" upon posting the OGDP application to our website. This public comment period allows the public to review OGDP applications and their components (i.e., proposed Oil and Gas Locations), and provide comments on those pending permit applications. How can I provide comments on pending permits in an OGDP? Members of the public can access OGDP applications through the COGCC website to review permit information and provide comments. Public comments may be made directly on Form 2A, Oil and Gas Location Assessment permit applications ("Form 2A") through the COGCC website. 1. Go to the COGCC website https://cogcc.state.co.us 2.

The Director may extend or reopen the public comment period per Rule 303.g, for up to an additional 30 days for a proposed OGDP if the Director determines an extension or reopening is reasonable in order to obtain public input. What happens to my comment? Your comment will become part of the public record of the application and will be reviewed by the applicant, COGCC staff, Director, and the Commission. COGCC staff may recommend permit conditions in response to comments. But, Staff does not routinely respond individually to comments; instead, COGCC staff will work directly with the applicant to address the site - specific concerns expressed. Submitted comments may not be immediately visible; it may be a few days before you see your comments posted. This delay allows COGCC supervisory staff to screen for offensive language prior to publication. What if I want to make my comment to the Commission? COGCC Staff and the Director review every comment received on a Form 2A permit application. They review the site specific concerns against the totality of the application materials, including the alternative location analysis, cumulative impacts evaluation, and best management practices proposed by the applicant. When the Director makes a recommendation to the Commission to either approve or deny an OGDP, that recommendation will include the consideration of the public comments received. In their review of an OGDP for a final determination at the administrative hearing, the Commission will have access to the entire record, including your public comment. Can I remain anonymous? Yes. Only the "Comment" portion of your submitted comment will be made publicly viewable. Your name and contact information will be kept confidential, and will only be used by COGCC staff to contact you if necessary in the course of permit application review. If you choose to include your name and contact information in the body of your comment text, it will be part of the public record.

The Colorado Oil and Gas Conservation Commission ("COGCC") prepared this information sheet to provide the public with information related to hydraulic fracturing. Pursuant to Commission Rule 303.e.(2).E, Operators' are required to provide this information sheet to mineral owners within the area of proposed development and all landowners, homeowners, commercial property owners, tenants, and other entities within 2,000 feet of a proposed oil and gas location. What is hydraulic fracturing treatment, and why is it necessary? Hydraulic fracturing treatment is the process of creating small cracks, or "fractures," in the rocks of deep, underground geological formations that have oil and natural gas. The fractures enhance the flow of oil and gas from the formation to the oil and gas well where it flows or is pumped up the well to the production equipment located on the surface of the site. The process of hydraulic fracturing has been used for decades in Colorado, dating back to the 1970s. Operators2 continue to improve hydraulic fracturing, and it is now a standard practice used in almost all oil and gas wells in the state, and across much of the country. Hydraulic fracturing has made it possible to produce oil and gas from rock formations that did not often produce oil and gas in the early to middle part of the twentieth century. What happens before hydraulic fracturing treatment? The operator uses a drilling rig to drill a "surface hole" and set a steel pipe called "surface casing" in the hole. The surface casing may extend many hundreds of feet, sometimes more than 1,000 ' "Operator" as defined in COGCC Rules 2 Hereinafter, and only for the purpose of describing the hydraulic fracture treatment process, the term "operator" includes the operator itself and all contractors and service providers that the operator hires to perform work. feet, underground. The operator places cement on the outside of the surface casing to seat and protect groundwater. The operator tests the surface casing with pressure, then a smatter "production hole" is drilled out the bottom of the surface casing. After completing a formation integrity test, the operator drills down to the geological formation containing oil and gas, usually many thousands of feet underground. The operator lowers a production casing into the production hole, and cement is used to make a seal above the deep oil and gas formation. The operator "completes" the well by placing holes, or "perforations" in the casing at the deep oil and gas formation, to allow oil and gas to flow into the well. The well is then ready for hydraulic fracturing treatment. What happens during and after hydraulic fracturing treatment? The operator performs the treatment by using high pressure water pumps to fracture the deep oil and gas rock formation. The pumps push fracturing fluids down the welt and out through the perforations, into the oil and gas rock formation. The hydraulic fracturing fluids are mostly water and sand, with a small amount of chemical additives. The sand, also called "proppant," remains in the fractures to help keep the fractures open allowing oil and gas to flow through the fractures to the perforations. After hydraulic fracture treatment, the well is allowed to "flowback," meaning hydraulic fracture fluids, oil, gas, and produced water from the formation flow through the perforations and up the welt to the surface where the fluids are separated. The operator sells the oil and gas. Waste products, mostly water produced from the oil and gas formation and hydraulic fracture fluids, are captured and stored for proper treatment or disposal. Page 2 Overhead view of a multiple -well site with hydraulic fracturing equipment set up inside a sound wall Common questions and answers about hydraulic fracturing treatment. Q: How is an oil and gas well designed to be protective of public health, the environment, and wildlife resources? A: COGCC engineering staff review all well permits to ensure that wells are lined with multiple layers of steel and cement sufficient to isolate groundwater from the deep oil and gas rock formations. The operator's wellbore design must meet COGCC wellbore isolation standards and rules in order to receive a permit to drill. Surface casing extends from the ground surface to 50 feet or more below groundwater. Production casing is cemented to seal the oil and gas formation in the well and prevent flow between groundwater and the oil and gas formations. The operator performs a well survey, called a "cement bond log," to verify the cement placement around the production casing. Additionally, the operator pressure tests surface equipment and ensures that nearby, "offset" welts that are close enough for pressure communication in the oil and gas formation have property -rated surface equipment or downhole plugs. Q: Will hydraulic fracturing treatment cause problems with water wells A: Water well problems related to hydraulic fracturing in Colorado are rare, which is largely a result of COGCC's long-standing mission to protect Waters of the State of Colorado, including groundwater. Most recently, the COGCC adopted new rules for wellbore isolation, effective November 2, 2020 to further strengthen this mandate. Geologic factors in Colorado also serve to help prevent groundwater impacts. Often, many thousands of feet of confining rock layers separate shallow groundwater formations that are used for drinking water, livestock, and irrigation from deep oil and gas formations. In cases where an operator intends to perform a hydraulic fracture treatment at a depth of less than 2,000 feet underground, a geological and engineering evaluation is required prior to approving a drilling permit. In cases where deep groundwater is present, COGCC rules require additional cement in oil and gas wells to seal the deep groundwater formations. Q: What is hydraulic fracture fluid? A: The COGCC and regulatory agencies of other oil and gas producing states partner with FracFocus, a Chemical Disclosure Registry, that operators use to report hydraulic fracture fluid chemical data (https: / /www.fracfocus.org/ ). According to FracFocus, approximately 98% to 99% of the fracturing fluid volume in most wells is water and sand. The remaining portion is made up of chemical additives used to reduce friction during pumping and prevent corrosion of the steel casing. Biocide is used to kill bacteria in the water. Surfactants promote water flowback from the formation, up the well and into the oil and gas production equipment at the well site or a nearby "tank battery." Fracturing chemicals are similar to other industrial chemicals which must be handled properly. COGCC rules require that operators properly store and handle chemicals in a manner that protects operator's employees, the public, the environment, and wildlife. COGCC rules require operators to publicly disclose the components and concentrations of fracturing chemicals for each well within 60 days of the hydraulic fracture treatment on the FracFocus website, which is searchable by county, operator, and well. The website also provides information on chemicals used and their purpose. Version 2.1 April 2, 2021 Page 3 Q: How are hydraulic fracturing fluids managed on the well site? A: Operators manage large volumes of drilling fluid, hydraulic fracturing fluid, and flowback during drilling and hydraulic fracturing treatment. Operators protect the public, environmental resources, and wildlife by implementing best management practices specified by permit conditions and COGCC rules for spill prevention. After hydraulic fracturing treatment, fluids return to production equipment at the well site as flowback. These flowback fluids are considered oil and gas Exploration and Production Waste ("EEtP Waste") that are recycled for other oil and gas operations, or are disposed of in accordance with state regulations. Marketable production fluids, including oil and gas, are separated and contained in tanks or vessels, or sent by pipeline to sales. Q: What can neighbors expect to experience during hydraulic fracturing treatment? A: The operator provides the COGCC and the local government a 48 -hour notice before performing hydraulic fracturing treatment. As the operator mobilizes the hydraulic fracturing crews, water tanks are placed at the site. The operator transports water to the site for hydraulic fracturing fluid by pipeline or water trucks. Heavy equipment, such as sand haulers, pump trucks, blending units and a control van arrives and the equipment is connected to the well with high pressure piping. The operator pressure tests the equipment, then the hydraulic fracture treatment begins. The work can take several days to several weeks, depending on the number of wells on the well site and the number of treatment stages needed for each well. The equipment noise from engines, pumps, and vehicles will be noticeable during the work. Induced seismicity from hydraulic fracturing is very low intensity, too small to be noticed by people at the ground surface, and therefore man-made earthquakes are not a common occurrence in Colorado during hydraulic fracturing treatment operations. Where can I get additional information? FracFocus (www.fracfocus.org) contains detailed information on hydraulic fracturing, chemicals used, groundwater protection and how to find a well near you.

Form O.10.2.3 Second Amended Exhibit C To Bison Dorado 36 OGDP Application BEFORE THE ENERGY AND CARBON MANAGEMENT COMMISSION OF THE STATE OF COLORADO IN THE MATTER OF THE APPLICATION OF BISON IV OPERATING, LLC FOR AN ORDER TO ESTABLISH AN APPROXIMATE 1,280 1,920 -ACRE DRILLING AND SPACING UNIT FOR 10 NEW HORIZONTAL WELLS WITHIN AN APPROXIMATE 1,296.6 1,936.6 -ACRE "DORADO 36" OIL AND GAS DEVELOPMENT PLAN FOR THE NIOBRARA, FORT HAYS, CODELL AND CARLILE FORMATIONS, WATTENBERG FIELD, WELD COUNTY, COLORADO CAUSE NO. 407 DOCKET NO. 240900210 TYPE: SPACING SECOND AMENDED APPLICATION COMES NOW Bison IV Operating, LLC (Operator No. 10670) ("Bison" or "Applicant"), by and through its attorneys, Jost Energy Law, P.C., and respectfully submits this Application to the Energy and Carbon Management Commission of the State of Colorado (the "Commission" or "ECMC") for an order to establish an approximate 1,280 1,920 -acre drilling and spacing unit for the below described Application Lands and approve 10 horizontal wells within the unit with subsurface setbacks of no closer than 300 feet from the boundaries of the unit at the well axis, no closer than 150 feet from the boundaries of the unit at the lateral ends, and no closer than 150 feet from the productive interval of any other welibore producing within the same common source or formation, unless authorized by Rule 401.c or Rule 408.u.(1) as applicable, for the production of oil, gas and associated hydrocarbons from the Niobrara, Fort Hays, Codell and Carlile Formations within the below -described Application Lands. In support of its Application, Applicant states and alleges as follows: 1. Applicant is a limited liability company duly organized and authorized to conduct business in the State of Colorado and is a registered operator in good standing with the Commission. 2. Applicant is an "Owner" and "Operator" as defined by the Oil and Gas Conservation Act and ECMC Rules, and owns leasehold interests or holds the right to operate on the following lands (hereafter "Application Lands"): Township 7 North, Range 63 West, 6th P.M. Section 33: All Section 34: All Section 35: All Surface Location: Dorado 36 Pad: approximately 16.6 -acres in the SEVNW% of Section 36, Township 7 North, Range 63 West, 6th P.M. Nearby Public Crossroads: C.R. 71 & Hwy 392 Page 1 of 7 A reference map of the Application Lands is attached hereto. 3. With this Application, Bison is providing a copy of an Oil and Gas Lease for at least one portion of a mineral tract within the Application Lands in which Bison is an owner and has the consent to operate in accordance with ECMC Rule 303.a.(1). See Exhibit B, submitted with the Dorado 36 OGDP Application. 4. Rule 401.a. provides that a Well completion 2,500 feet or greater below the surface will be located not less than 600 feet from any lease line and not less than 1,200 feet from any other existing or permitted Well completion in the same common source of supply, unless authorized by order of the Commission or an exception under Rule 401.c is obtained. The Application Lands are unspaced and subject to this Order. 5. On April 27, 1998, the Commission adopted Rule 318A, the Greater Wattenberg Area Special Well Location, Spacing and Unit Designation Rule. The Application Lands are subject to this Rule for the Niobrara and Codell Formations. Effective January 15, 2021, Commission Rule 318A was moved to Rule 402 and modified to have no effect on future operations and development in the Greater Wattenberg Area. However, Rule 402.c states that any wellbore spacing units established prior to January 15, 2021 will remain in effect unless the applicable Form 2s, if any, expire without spud. 6. The records of the Commission reflect that the following horizontal wells are currently producing (PR), temporarily abandoned (TA) or shut in (SI) within the Application Lands from the Niobrara, Fort Hays, Codell and/or Carlile Formations, operatcd by PDC Energy, Inc., within horizontal wellbore spacing units designated under Rule 318A and/or wellbore specific orders for portions of the Application Lands: Well Name API No. Location ID Operator Status Wilson #34-34H 05-123-32972 421609 PDC Energy PR Wilson #14-34H 05-123-34358 425363 PDC Energy PR KEHN USX AC #35- 13 05-123-26152 310264 Noble Energy PR WAHLERT AC #33- 68HN 05-123-34519 425782 Noble Energy PR WAHLERT AC #33- 67HN 05-123-34522 425782 Noble Energy TA WAHLERT AC #33- 66HN 05-123-34517 425782 Noble Energy PR WAHLERT AC #33- 65HN 05-123-34521 425779 Noble Energy PR WAHLERT AC #33- 64HN 05-123-34523 425779 Noble Energy SI WAHLERT AC #33- 63HN 05-123-34518 425779 Noble Energy PR 7. Bison states that the above referenced Wells will continue to produce and allocated proceeds, if any, in accordance with Rule 318A or a designated spacing order and will not be affected by the relief requested in this Application. Page 2 of 7 8. The records of the Commission reflect that the following horizontal wells are currently producing (PR) adjacent to the Application Lands from the Niobrara, Fort Hays, Codell and/or Carlile Formations, operated by Noble Energy, Inc., within horizontal wellbore spacing units designated under Rule 318A overlapping portions of the Application Lands: Well Name API No. Location ID CROW CREEK STATE #AC36-79-1HN 05-123-37278 432765 NCLP PC AA #04-69-1 HN 05-123-37179 432598 9. Bison states that the above referenced Wells will continue to produce and allocated proceeds, if any, in accordance with Rule 318A, and will not be affected by the relief requested in this Application. 10. Bison will utilize the new Dorado 36 Oil and Gas Location for the development of 10 new horizontal Wells in the Application Lands. With this Application, Bison submitted sworn testimony pursuant to Rule 505 regarding its protective development of the proposed Location and that no criteria listed in Rule 304.b.(2).B apply to the proposed Oil and Gas Location. The new Dorado 36 Pad is subject to the Dorado 36 OGDP Application filed concurrently herewith. 11. Based on the location of the new Dorado 36 Oil and Gas Location, Weld County is the jurisdiction with siting authority. Bison is concurrently seeking a 1041 WOGLA siting permit from Weld County for the siting and related surface disturbance of the Dorado 36 Oil and Gas Location. 12. Bison anticipates that it will submit an application to pool all interests, including any non -consent interests, within the Application Lands at a future date. Bison owns or has the consent of the owners of over 45% of the leasehold interests in the Application Lands, and therefore Bison may pool the proposed Wells in the Application Lands pursuant to the requirements of C.R.S. § 34-60-116(6)(b)(I), subject to the requirement to tender a reasonable and good faith lease offer to all unleased mineral interest owners within the Application Lands in accordance with C.R.S. § 34-60-116(7)(d)(I). 13. The drilling and spacing unit contains fee minerals. The surface location for the proposed Dorado 36 Pad is located on State Land Board surface and Bison entered into a Surface Use Agreement with the State Land Board for the proposed Dorado 36 Oil and Gas Location and associated disturbance. 14. Bison certifies that the drilling and spacing unit will result in development that will protect and minimize adverse impacts to public health, safety, and welfare, the environment, and wildlife resources and will protect against adverse environmental impacts on any air, water, soil or biological resource in compliance with C.R.S. § 34-60-106(2.5)(a). Bison certifies that its operations in the Application Lands will be conducted in a reasonable manner to protect and minimize adverse impacts to public health, safety, welfare, the environment, and wildlife resources. With this Application, Bison submitted sworn testimony pursuant to Rule 505 supporting the protection of public health, safety, welfare, the environment and wildlife resources. 15. Bison further certifies that the drilling and spacing unit prevents waste of oil and gas resources, avoids the drilling of unnecessary Wells, and protects correlative rights. With this Application, Bison submitted sworn testimony pursuant to Rule 505 supporting the prevention of waste, the avoidance of drilling unnecessary Wells, and the protection of correlative rights. Page 3 of 7 16. Bison requests that the spacing order establish subsurface setbacks of 300 feet from the boundaries of the unit at the well axis, 150 feet from the boundaries of the unit at the lateral ends, and provide that all horizontal wells will be no closer than 150 feet from the productive interval of any other wellbore located in the same formation or common source of supply, unless authorized by Rule 401.c or Rule 408.u.(1) as applicable. The Wells within the Application Lands will be drilled from an east -west lateral orientation. 17. The undersigned certifies that copies of this Application and the Notice of Hearing will be served on each interested party as required by Rules 504.a., 504.b.(2) and 504.b.(6). 18. The granting of this Application is in accord with the Oil and Gas Conservation Act, found at §§ 34-60-101 et seq., C.R.S., and the Commission Rules. 19. Applicant requests that relief granted under this Application should be effective on oral order by the Commission, and Applicant hereby agrees to be bound by said oral order. WHEREFORE, Bison respectfully requests that this matter be set for hearing in accordance with applicable Commission Rules, that notice be given as required by law, and that upon such hearing this Commission enter its order to: A. Establish an approximate 1,280 1,920 -acre drilling and spacing unit for the Application Lands and approve 10 new horizontal wells within the unit for the development of the Niobrara, Fort Hays, Codell and Carlile Formations; B. Authorize subsurface setbacks of no closer than 300 feet from the boundaries of the unit at the well axis, no closer than 150 feet from the boundaries of the unit at the lateral ends, and no closer than 150 feet from the productive interval of any other wellbore producing within the same common source or formation for the development of the Niobrara, Fort Hays, Codell and Carlile Formations, unless authorized by Rule 401.c or Rule 408.u.(1) as applicable; C. Provide that all new authorized wells will be developed from the new Dorado 36 Oil and Gas Location located adjacent to the Application Lands, unless an exception is granted by the Director; D. Find that the establishment of the drilling and spacing unit for the development of the Niobrara, Fort Hays, Codell and Carlile Formations will prevent waste of oil and gas resources, avoid the drilling of unnecessary Wells, protect correlative rights, and protect public health, safety, welfare, the environment and wildlife resources; and E. For such other findings and orders as the Commission may deem proper or advisable in this matter. DATED December 23, 2024.

Sand is then pumped into the created fracture to allow gasand oil to flow freelyfrom the formation into the well bore. The fracturing equipment u 1 consist of one Modular Large Volume Tank (MLVT) for fresh water storage, multiple floes tanks, pressure (pumps, blending and bulk material trucks with other necessary equipment. After fracturing is completed, the mobile equipment is removed, excluding tanks that are used to retain the water that is produced during flowback and testing operations. No water is allowed to aocumu . te.or be disposed of on surface. All water is hauled to approved disposal sites or recycled formulation use. The flowback tanks will remain on location until the well is rerouted through standard production equipment. The production ,equii eut for these wells will be located adjacent to the wells. Typpicail equipment will consist of oil and water tanks constructed within berms comprised of steel rings with a synthetic or engineered lil ner, separators, vapor recovery and emission control equipment, gas compressor's, meters, flo il'anes, and proposed electrical and/or solar equipment. The location will, include automation equipment that allows operators to remotely monitor pressures, rates, temperatures, valve positions and tank levels. 'Once production commences, a Bison employee or contractor will monitor the location on a regularly scheduled basis. These inspections are done as a routine part of the lease operator's job. They conduct a visual inspection of the fatality which includes all valves, fittings, wellhead, tanks, vapor control systems and all connections. The lease operator reports the tank measurements of the off, ,gas sales, ,and pressure readings. Much of this production information is compiled and submitted to ,the &MAC on .a monthly basis. In :addilaon, be lease operator will inspect the site for hazards and weed control, maintaining the safety arid ,appearance of the Pads. The antiailaated lfifespan for the proposed well(S) its 30 years. Once a well is deter rued to no longer be probative aridlor,econontic, a plugging rig will remove production equipment andl plug the pre dative :zone %with aiconibination of brtrdge plugs and cement plugs. Surface 'equipment rno longer rid trill be,rid. (Final surface restoration will involve the removal ofany .above ;ground casing and the installation of ;regulation imarlkers that will not interfere witln subsequent surface use. The remaining disturbance areas will be restored to the original grade and reseeded in compliance criith ;KINK ;and Local 'Government rules .and regulations and in accordance with.surface owner's future land use plans. The expected travel routes for the proposed oil and gas location would follow Highway 392 to Weld County Road 74, then continue southeast 0.25 miles on Weld County Road 74 before continuing east on Weld County Road 74 for approximately 0.8 miles, then continue approximately 0.8 miles north and northeast on an access road to the proposed location.

During this "active operations" phase, vebide traffic will include passenger cars and pickups, semi-truck/trailers, and tandem truck vehicles. The number of round trips per day expected for each vehicle during active operations is summarized in Table 2: Estimated Traffic during Active Operations below. The highest traffic volumes are expected during the first two days of and the last two days of both drilling and completion operations. Traffic will intentionally be highest during daylight hours to mitigate noise and dust during non -working hours.
