The following changes from the previously approved Form 2 are being made via this refile: The Qtr-Qtr was changed from NENW to Lot 2 as reflected in the Well Location Plat previously submitted (Doc#401825542). The Mineral Lease Description was updated to reflect the Fee lease description. The surface casing set depth was updated to 1450' MD. The previously submitted Deviated Drill Plan (Doc#401825545) reflects this depth. BMPs were updated to remove operator name, however no substantial changes were made. The Windows/Twinning exception location waiver (doc#401828007) was submitted with the original approved Form 2 (doc#401825374 ). The nearest well in the same formation has been updated based on GIS review, see details below. The 2015 SUA has been attached as a supplemental document to the originally submitted 2018 SUA Memorandum (doc#401828903). The STATE ANTELOPE 34-32-29XRLNC (123-50050), permitted by Bonanza Creek Energy Operating Co. LLC is the nearest well in the same formation, the distance was measured in 2D. Status XX. No wells owned by other operators are Producing, Temporarily Abandoned, or Shut-In within 150' of this wells productive lateral, therefore stimulation setback consent is not needed. 402492926 402492926 FORM 2 SUBMITTED 402492926.pdf 402492926 402498992 SURFACE AGRMT/SURETY 70 Ranch 1st Amended SUA 2015 RECORDED - FOR PERMITTING.pdf 935290 402492926 402506439 OffsetWellEvaluations Data Seventy Holes K-5 Pad_OffsetWellEvaluations_North Wells 10.1.20_ALN.xlsx 69773 35785e5a-451f-4b2f-b962-971b9fec30b8 402492926 3 Drilling/Completion Operations 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 a1fcb468-13e4-4b22-ab54-e59d7fa9db66 402492926 1 Drilling/Completion Operations Operator will comply with the “COGCC Policy for Bradenhead Monitoring during Hydraulic Fracturing Treatments in the Greater Wattenberg Area”, dated May 29, 2012. false 0eeb75df-8a54-4f60-a1e1-e7c0d25b04b3 402492926 2 Drilling/Completion Operations 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 402492926 1ST 8 1 2 5 1 2 17 11546 2036 11546 0 PLANNED false false false 402492926 SURF 13 1 2 9 5 8 36 1450 511 1450 0 0 PLANNED false false false 402492926 NIOBRARA NBRR 400 GWA Thread was being aborted.
