Nearest well belonging to another operator is Merlin 29E-10-3C, 123-47465, operated by Extraction Oil and Gas. The distance was measured in 3D. The completed portions are more than 150' apart. 408.t notice will be sent. Also within 150' is Merlin 29E-10-4N, 123-47467, operated by Extraction Oil and Gas. The distance was measured in 3D. The completed portions are more than 150' apart. 408.t notice will be sent. Also within 150' are MacLougan 25-1, 123-06196, operated by UniOil and Thayer 2-30, 123-12031, operated by Walter Propereties. The distance was measured in 2D. Closest point is in the completed portions. Well status of MacLougan 25-1 is PA. No consent required. Well status of Thayer 2-30 is DA. No consent required. The API is being reused from a previously submitted Raindance APD. Every aspect of the wellbore is changing including the well name, drilling and casing program, offset well evaluation and attachments. 402080773 402080773 FORM 2 RESUBMITTED 402080773.pdf 402080773 402497973 FORM 2 REJECTED 402497973.pdf 402080773 402505699 MINERAL LEASE MAP Raindance Mineral Lease Map.pdf 99701 402080773 402507984 WELL LOCATION PLAT Raindance 26-272HN_Well Plat 2018.pdf 716082 402080773 402507985 DIRECTIONAL DATA 26-272HN COGCC Survey.xlsm 31133 402080773 402598366 OffsetWellEvaluations Data OffsetWellEvaluation Raindance 23-36Refiles 02082021.xlsx 45887 402080773 402608098 DEVIATED DRILLING PLAN Raindance FC 26-272HN - Plot - 20181212.pdf 391355 e637ac29-e4f0-403d-b4ac-29af681cefb7 402080773 5 Drilling/Completion Operations Bradenhead Monitoring – Rule 419 Great Western will comply with Rule 419 and Order 1-232 for all Bradenhead compliance, as applicable. false 9dc35b0c-9c22-44d8-9abf-36976d7bb439 402080773 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. Operator will perform anti-collision evaluation of all active (Producing, Shut In, or Temporarily Abandoned) offset wellbores that have the potential of being within 150’ of a proposed well prior to drilling operations for the proposed well. Notice shall be given to all offset operators prior to drilling. false 119890c6-ba30-49c5-9317-73e9509faf45 402080773 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 5df249e2-cbdd-451f-8010-8ea9f19816da 402080773 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 9be90a8d-a963-4de0-b990-e9ce4b82e23b 402080773 4 Drilling/Completion Operations Multi Well Open-Hole Logging – Rule 408.r Alternative Logging Program: One of the first wells drilled on the pad will be logged with open-hole resistivity log and gamma-ray log from the kick-off point into the surface casing. All wells on the pad will have a cement bond log with gamma-ray run on production casing (or on intermediate casing if production liner is run) into the surface casing. The horizontal portion of every well will be logged with a measured-while-drilling gamma-ray log. The Form 5, Completion Report, for each well on the pad will list all logs run and have those logs attached. The Form 5 for a well without open-hole logs shall state “Alternative Logging Program - No open-hole logs were run” and shall clearly identify the type of log and the well (by API#) in which open-hole logs were run. false 402080773 1ST 8 1 2 5 1 2 20 19817 2720 19817 3420 0 PLANNED HCP-110 false false false 402080773 SURF 13 1 2 9 5 8 36 2000 844 2000 0 0 PLANNED J-55 false false false 402080773 NIOBRARA NBRR 407-1900 771 T6N R67W: Sec 30:S2; T6N R68W: Sec 25:S2; Sec 26:SE4 Thread was being aborted.
