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 2455' FNL and 2340' FEL of Section 24. The wellbore beyond the unit boundary setback will be physically isolated and will not be completed. Nearest wellbore permitted or completed in the same formation is the Castor Fed 8-59 19-24-5 (Bison Oil & Gas II, LLC), as measured using 2D manual calculations. Nearest existing or permitted wellbore belonging to another operator is the Peterson PC LG 19-06 API 05-123-33378 (Noble Energy Inc), measured using 2D manual calculations. 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. 402016952 402016952 FORM 2 SUBMITTED 402016952.pdf 402016952 402016961 DIRECTIONAL DATA PROPOSAL #3 - CASTOR FED 8-59 19-24-6.xlsx 26132 402016952 402016964 WELL LOCATION PLAT Castor Fed 8-59 19-24-6 WLP.pdf 833292 402016952 402016966 DEVIATED DRILLING PLAN PROPOSAL #3 - CASTOR FED 8-59 19-24-6.pdf 80770 402016952 402016991 OffsetWellEvaluations Data Offset Well Evaluation Castor 8-59 19 Pad_Updated 4.22.19.xlsx 41276 3e480581-9b83-4eaf-bfb5-1cc52ea5dabf 402016952 1 Drilling/Completion Operations An existing well on the pad was logged with open-hole resistivity log with 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 “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 c4e0f882-60dc-42ba-bd2e-69254b7c7e58 402016952 3 Drilling/Completion Operations Anti-collision: Operator will perform an anti-collision evaluation of all active (producing, shut in, or temporarily abandoned) offset wellbores that have the potential of being within 150 feet of a proposed well prior to drilling operations for the proposed well. Notice shall be given to all offset operators prior to drilling. false 326a1211-433c-4671-9585-a8076ab9075d 402016952 2 Drilling/Completion Operations When a skid is performed, if a previous well on that pad has completed a full BOPE test within the past 21 days, then the only required BOPE tests are for the BOPE connections that were broken during the skid. The purpose of this is to prevent the wear and tear on the choke line and kill line valves. The annular and double rams will be tested as per usual and all broken connections will also be tested (annular to 70% of rated pressure, all other valves and connections will be tested to full rated pressure). Under no circumstances will 21 days be exceeded without completing a full BOPE test to all connections including all choke and kill line valves. Daily function test / activation of pipe rams are still required in addition to a preventer operator test on each trip. false 402016952 1ST 8 1 2 5 1 2 20 14345 1860 14345 4000 0 PLANNED 402016952 CONDUCTOR 26 16 43 100 50 100 0 0 PLANNED 402016952 SURF 13 1 2 9 5 8 36 1850 650 1850 0 0 PLANNED 402016952 NIOBRARA NBRR 960 S.19: ALL S.24: E2 Thread was being aborted.
