The WOGLA application will be submitted in tandem with this APD & corresponding Form 2A. The Big Mountain Viper Fed 8-59 16-17-18-4 (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 DOROTHY STATE #LG16-785 [API #: 123- 47611], operated by NOBLE ENERGY INC. The distance was measured using 3D manual calculations. The well status is PR. 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. 402052255 402052255 FORM 2 SUBMITTED 402052255.pdf 402052255 402052258 DIRECTIONAL DATA PROPOSAL #1 - BIG MOUNTAIN VIPER FED 8-59 16-17-18-5.xlsx 25973 402052255 402052261 SURFACE AGRMT/SURETY SLB SUA_Permits_Redacted.pdf 7283993 402052255 402052262 DEVIATED DRILLING PLAN PROPOSAL #1 - BIG MOUNTAIN VIPER FED 8-59 16-17-18-5.pdf 77975 402052255 402052263 WELL LOCATION PLAT BMV 16-17-18-5 WLP.pdf 849171 402052255 402052264 OffsetWellEvaluations Data Offset Well Evaluation Big Mountain Viper Fed 8-59 16.xlsx 41579 402052255 402026015 02A Big Mountain Viper 8-59 16 99114b51-634f-4187-883a-647390516086 402052255 1 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 ab116895-9868-46f0-8bf4-8b5948d91239 402052255 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 150edb8e-6081-4023-a36d-f3ca9754453f 402052255 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 402052255 1ST 8 1 2 5 1 2 20 14210 1860 14210 4000 0 PLANNED 402052255 CONDUCTOR 26 16 43 100 50 100 0 0 PLANNED 402052255 SURF 13 1 2 9 5 8 36 1850 650 1850 0 0 PLANNED 402052255 NIOBRARA NBRR 1920 S.13, 17, 18: ALL Thread was being aborted.
