The Grotheer 5-61 11A-2-4 [Doc #: 401949613] (Bison Oil & Gas II, LLC), is the nearest well in the same formation, the distance was measured using 2D manual calculations. The nearest wellbore belonging to another operator was measured to the HENDERSHOT ETAL #13-11 [API #: 123-11034], operated by FRITZLER RESOURCES INC. The distance was measured using 2D manual calculations. The well status is SI. 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. 401949612 401949612 FORM 2 SUBMITTED 401949612.pdf 401949612 401955415 WELL LOCATION PLAT 11A-2-3 WLP.pdf 797994 401949612 401955416 DEVIATED DRILLING PLAN PROPOSAL #1 - GROTHEER 5-61 11A-2-3.pdf 105811 401949612 401955418 DIRECTIONAL DATA PROPOSAL #1 - GROTHEER 5-61 11A-2-3.xlsx 25905 401949612 401956889 EXCEPTION LOC REQUEST Exception Location Request.pdf 241919 401949612 401957286 OffsetWellEvaluations Data Offset Well Evaluation Grotheer 5-61 11A-14.xlsx 42113 401949612 401961930 SURFACE AGRMT/SURETY Grotheer Executed SUA.pdf 3497806 401949612 401949715 02A Grotheer 5-61 11A OGLA 0e345508-cb57-48e4-b567-08f44723b9b9 401949612 3 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 c4156553-281a-46ac-a423-4790eb65e43e 401949612 4 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 365d53e4-4565-4826-b685-613908d932fd 401949612 2 Drilling/Completion Operations 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-whiledrilling 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 2aaef7b4-7b1e-4726-b7e6-ae52110a0c0b 401949612 1 Drilling/Completion Operations Bison Oil & Gas II will comply with the “COGCC Policy for Bradenhead Monitoring during Hydraulic Fracturing Treatments in the Greater Wattenberg Area”, dated May 29, 2012 false 401949612 1ST 8 1 2 5 1 2 20 16339 1860 16339 4000 0 PLANNED 401949612 CONDUCTOR 26 16 43 100 50 100 0 0 PLANNED 401949612 SURF 13 1 2 9 5 8 36 1850 650 1850 0 0 PLANNED 401949612 NIOBRARA NBRR 1280 S.11 & S.2: ALL Thread was being aborted.
