The effective date of the 1041 WOGLA Permit Process was 02/01/2017, therefore the local government does not precede the COGCC in siting determination at this location. Additionally, the Weld County LGD left the following comment on the Kodak South FD Pad (Location ID: 306149) approved Form 2A (Document Number 401163313). “This proposed oil and gas facility is located in unincorporated Weld County in the Industrial (I-1) Zoned District. As of today’s date, January 27, 2017, the Weld County Oil and Gas Liaison/LGD has not been contacted by any nearby resident(s) or governmental jurisdiction(s) regarding this proposed location. The County will respond to legitimate concerns or issues regarding proposed locations and attempt to facilitate a solution with the operator. Prior to a recent code change Oil Gas Production Facilities in the Industrial Zoned District were an allowed use with no Site Plan Review required. The COGCC Form 2A for this location was submitted on or before February 1, 2017. The proposed use remains a Use by Right with no Weld Oil and Gas Location Assessment (WOGLA) required. A building permit is required for the production facilities (tank battery, separators, pump jacks, compressors, generators, etc.) and the operator has a Flood Hazard Development Permit (FHDP15-0067) from the Department of Planning Services.

Distance from the proposed wellbore to nearest existing or proposed wellbore belonging to another operator, including plugged and abandoned wells, was measured to the POUDRE 15-28, API No 05-123-26630, SI Status, owned by Kerr McGee Oil & Gas Onshore LP, and is measured using in-house 3D anti-collision reports. The API is being reused from a previously submitted Kodak South APD. Some aspect of the wellbore are changing including the TPZ and BHL, Spacing Order, TD, drilling and casing program, offset well evaluation, Operator BMPs, well name, and attachments. Great Western has requested an open hole logging exception to Rule 408.r for the proposed well. The 408.r exception request is attached. 402518587 402518587 FORM 2 SUBMITTED 402518587.pdf 402518587 402524668 WELL LOCATION PLAT Well Location Plat_Kodak South FD 28-339HC_2020.pdf 778834 402518587 402533432 MINERAL LEASE MAP Kodak South Lease Map.pdf 95659 402518587 402535100 DIRECTIONAL DATA Kodak South FD 28-339HC - COGCC Survey - 20201111.xlsm 46678 402518587 402645155 DEVIATED DRILLING PLAN Kodak South FD 28-339HC_Updated Deviated Drilling Plan_PDF.pdf 221533 402518587 402652043 OPEN HOLE LOGGING EXCEPTION Kodak South Pad Logging Exception Letter.pdf 167635 402518587 402652047 OffsetWellEvaluations Data OffsetWellEvaluations Kodak South (West) 04-07-2021.xlsx 38856 e821e08f-fe65-4cbc-891c-287567999adc 402518587 4 Drilling/Completion Operations Bradenhead Monitoring Great Western will comply with Rule 419 and Order 1-232 for all Bradenhead compliance, as applicable. false eb72c8c2-470c-4cda-8848-46916043d9b5 402518587 5 Drilling/Completion Operations Multi Well Open-Hole Logging – Rule 408.r Alternative Logging Program: One of the first wells already drilled on this pad (Kodak South FD 25-241HC, API 05-123-44116) has a triple combination open hole resistivity log with gamma ray in the well file. All additional proposed wells will have a cement bond log with gamma ray run from the intermediate casing shoe, or as close as possible, to above surface casing shoe to verify the setting depth of surface casing and aquifer coverage. The horizontal portion of all subject wells will be logged while drilling with a gamma ray tool. The Form 5 for each well shall clearly state, “No open hole logs were run” and shall reference the Rule 408.r Exception granted for the well. The Form 5 for each well on the pad will identify the well that was logged with alternative logs by API number, well name and well number. false fdd69ee3-1068-4b3c-af59-53d7cf702bfe 402518587 2 Drilling/Completion Operations Wellbore Collision Prevention – Rule 408.t Prior to drilling operations, Great Western will perform an anti-collision scan of existing offset wells that have the potential of being within close proximity of the proposed well. This anti-collision scan will include definitive MWD or gyro surveys of the offset wells with included error of uncertainty per survey instrument and compared against the proposed well path with its respective error of uncertainty. If current surveys do not exist for the offset wells, Operator may have gyro surveys conducted to verify bottom hole location. The proposed well will only be drilled if the anti-collision scan results indicate that there is not a risk for collision, or harm to people or the environment. false 3fbc7b42-6ca8-498a-842b-8754e2bd9580 402518587 3 Drilling/Completion Operations Stimulation Setback – Rule 408.u Great Western shall obtain signed written consent for any portion of the proposed wellbore’s treated interval within 150’ of an existing (producing, Shut-in, or temporarily abandoned) or permitted oil and gas well’s treated interval belonging to another operator prior to completion of the well. false 1b20cc1f-2b68-4d9a-a3bb-b553378b9d08 402518587 1 Drilling/Completion Operations Drill Stem Tests – Rule 603.g Conventional drill stem tests will not be conducted on DJ Basin horizontal wells currently being executed or planned by Great Western. If plans change in the future a well specific drill stem testing plan will be prepared for that particular well. Note that Great Western may elect to use one of several available wireline deployed tools for the purpose of measuring down hole formation pressures and/or collecting down hole fluid samples from the target formation(s) of a particular well. false 402518587 1ST 8 1 2 5 1 2 20 18492 2520 18492 3300 0 PLANNED HCP-110 false false false 402518587 SURF 13 1 2 9 5 8 36 2000 844 2000 0 0 PLANNED J-55 false false false 402518587 CODELL CODL 407-3195 712 T6N-R67W; Sec 26: W1/2 SW1/4; Sec 27: S1/2; Sec 28: S1/2 Thread was being aborted.
