The well status is currently PR. No wells owned by other operators are Producing, Temporarily Abandoned, or Shut-In with treated intervals within 150' of this well's productive lateral, therefore stimulation setback consent is not needed. 402010153 402010153 FORM 2 RESUBMITTED 402010153.pdf 402010153 402484292 OffsetWellEvaluations Data LF@5241852|402484292 402010153 402486365 FORM 2 REJECTED 402486365.pdf 402010153 402486982 DIRECTIONAL DATA Pronghorn Federal A-E-31HNB (REV-D.0) Directional Data.xlsx 30738 402010153 402486983 DEVIATED DRILLING PLAN PRONGHORN FEDERAL A-E-31HNB (REV-D.0) WELL PLAN.PDF 205084 402010153 402486985 WELL LOCATION PLAT WLC_07_PRONGHORN FEDERAL A-E-31HNB (2020-02-27).pdf 1423082 402010153 402487065 OffsetWellEvaluations Data Pronghorn 13-30_South OffsetWellEvaluations_REV.9.8.20.xlsx 62128 402010153 402487401 EXCEPTION LOC REQUEST PRONGHORN 13-30_Exception Location Request Letter Windows_9.11.2020.pdf 180760 402010153 402487574 PROPOSED SPACING UNIT A-E-31HNB PSU Letter w Exhibits_9-11-2020..pdf 241035 402010153 402488835 SURFACE AGRMT/SURETY Riverside_SUA.pdf 106403 402010153 402488873 EXCEPTION LOC WAIVERS Exp Location Waiver_Rev-Reg_09-14-2020.pdf 602093 b8cca9db-3c65-4d20-b580-4f98eb7481ca 402010153 3 Drilling/Completion Operations Alternative Logging Program: One of the first wells drilled on the pad will be logged with an open-hole resistivity log and gamma-ray, from the kick-off point into the surface casing. All wells on the pad will have a cement bond log (CBL) 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 clearly 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 e882e574-9a00-44c6-96b0-ab3cd4fc8754 402010153 1 Drilling/Completion Operations Bradenhead Monitoring Operator will comply with the “COGCC Policy for Bradenhead Monitoring during Hydraulic Fracturing Treatments in the Greater Wattenberg Area”, dated May 29, 2012. false 4a00f730-0e19-4185-b4b3-ff25f4284cf9 402010153 2 Drilling/Completion Operations Wellbore Collision Prevention – Rule 317.r Prior to drilling operations, Operator 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 402010153 1ST 8 1 2 5 1 2 17 11669 1832 11669 0 0 PLANNED false false false 402010153 SURF 13 1 2 9 5 8 36 1600 743 1600 0 0 PLANNED false false false 402010153 NIOBRARA NBRR 445 GWA Thread was being aborted.
