Nearest well belonging to another operator is Merlin 29E-10-1C, 123-47464, operated by Extraction Oil and Gas. The distance was measured in 3D. The completed portions are more than 150' apart. 317.r notice will be sent. This is a refile Form 2; there are changes to the Surface Hole Location, safety setback distances, Total Depth, casing and cement program, and Drilling and Spacing Unit. Updated Offset Well Evaluation, well location plat, deviated drilling plan, and directional data template are attached. This well has a bottom-hole location beyond the unit boundary setback. The bottom of the completed interval will be within the unit boundary setback at 2549’ FNL and 2050’ FEL of Section 26. The wellbore beyond the unit boundary setback will be physically isolated and will not be completed. 402718016 402718016 FORM 2 SUBMITTED 402718016.pdf 402718016 402725817 MINERAL LEASE MAP RaindancePad_MineralLeaseMap.pdf 99701 402718016 402745678 WELL LOCATION PLAT RaindanceFC26-192HC_WellLocationPlat_07122021.pdf 904496 402718016 402745679 DEVIATED DRILLING PLAN Raindance FC 26-192HC_combinedsurveyanddirectionaldatatemplate_20210706.pdf 257321 402718016 402745681 DIRECTIONAL DATA Raindance FC 26-192HC - COGCC Survey - 20210706.xlsm 65757 402718016 402748457 OffsetWellEvaluations Data Copy of OffsetWellEvaluation Raindance 3 BoundaryWells 07132021.xlsx 30596 c8502d5c-a5a1-41d0-8906-3b27a33b78d9 402718016 2 Drilling/Completion Operations 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 the 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 5d6c7743-ca02-4458-8bae-3b93cfd27c8b 402718016 3 Drilling/Completion Operations 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 132c2587-8f78-42c0-8c32-3df8d9c5e2fe 402718016 5 Drilling/Completion Operations Multi Well Open-Hole Logging – Rule 408.r Alternative Logging Program: An existing well on the pad was 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 4e88c51f-869c-4a63-8cf9-adb489125df3 402718016 4 Drilling/Completion Operations Great Western will comply with Rule 419 and Order 1-232 for all Bradenhead compliance, as applicable. false 6accb5a4-fc0f-4364-b50a-ea4613728215 402718016 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 402718016 1ST 8 1 2 5 1 2 17 19614 2652 19614 2853 0 PLANNED HCP-11 false false false 402718016 SURF 13 1 2 9 5 8 36 2000 844 2000 0 0 PLANNED J-55 false false false 402718016 CODELL CODL 407-3217 776 T6N-R67W (Weld County): Sec 30: N/2S/2,S/2N/2; T6N-R68W (Larimer County): Sec 25: N/2S/2,S/2N/2; Sec 26:S/2NE/4,N/2SE/4 Thread was being aborted.
