No WOGLA amendments are required at this time. false WOGLA 2018-09-05T00:00:00-06:00 402237653 This refiled APD is being submitted to update the following: SHL, TPZ, BHL, and minor depth related changes to the casing and cement program. 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 300’ FSL and 300' FWL of Section 9. 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 Stampede Fed 8-60 4-9-2 (Bison Oil & Gas II, LLC), measured using 2D manual calculations. Nearest existing or permitted wellbore belonging to another operator is the State 8-60 #16-2H [API 05-123-34824], operated by Noble Energy Inc., measured using 2D 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. 402237653 402237653 FORM 2 SUBMITTED 402237653.pdf 402237653 402237662 WELL LOCATION PLAT Stampede Fed 8-60 4-9-1 WLC_11-08-19.pdf 866460 402237653 402237663 DEVIATED DRILLING PLAN PROPOSAL #3 - STAMPEDE FED 8-60 4-9-1.pdf 106606 402237653 402238799 DIRECTIONAL DATA PROPOSAL #3 - STAMPEDE FED 8-60 4-9-1.xlsx 26361 402237653 402260763 OffsetWellEvaluations Data Offset Well Evaluation Stampede Fed 8-60 4_2019 (EW Edit).xlsx 45918 a7f5db4f-ad22-46ef-9158-676fede737cc 402237653 2 Drilling/Completion Operations Alternative Logging Program -An existing well on the pad was logged with Open Hole Resistivity Log and Gamma Ray Log from the kick-off point to 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 measuredwhile-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 openhole logs shall clearly state "Alternative Logging Program - No open-hole logs were run" and shall clearly identify (by API#, well name & number) the well in which openhole logs were run. false 5ab23bd8-376a-4e57-a4ec-b1fd7ae23a0a 402237653 1 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 b7c0eb80-0e44-4024-999f-019636439b0e 402237653 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 402237653 1ST 8 1 2 5 1 2 20 17235 1860 17235 4000 0 PLANNED 402237653 CONDUCTOR 26 16 43 100 50 100 0 0 PLANNED 402237653 SURF 13 1 2 9 5 8 36 1850 650 1850 0 0 PLANNED 402237653 NIOBRARA NBRR 535-1106 1280 S.4 & S.9: ALL Thread was being aborted.
