The CLR Colter wells in Bear Creek are beginning to report. Scroll through the list at this post as well as the data below on this post to see some incredible Colter wells. It appears:
  • three targets: middle Bakken; Three Forks, first bench; Three Forks, second bench
  • in addition, one well may have targeted the third bench (based on legal name of the well); geologic record not on file; NDIC has asked for geologic record for that well (see below)

From the file reports.
  • 32896:
    • spud date: February 6, 2018
    • TD date: March 3, 2018
    • TD: 21,684 feet
    • target: Three Forks, first bench
    • drilled out of the shoe: February 27, 2018
    • two trips were necessary; both near the end of the lateral
    • background gas: very low
    • Mississippian Lodgepole: 10,260 feet
    • Mississippian Upper Bakken: 11,122 feet
    • Lower Mississippian-Upper Devonian Middle Bakken: 11,139 feet
    • middle Bakken: 34 feet thick
    • Upper Devonian Lower Bakken: 11,173 feet  
    • Upper Devonian Three Forks: 11,190 feet
    • target: approx 18' thick, beginning 15' below the Three Forks top, and extending 33' below the same reference point
    • "... drilling parameters did not show any indication or warning of a shale strike (or we may have proceeded to a point of gamma confirmation), nor did the last sample, cleaned with Herculean efforts, produce any shale cuttings save those mudstone pieces typical of the Three Forks."
    • "The hypothetical conclusion drawn is that we hit something hard, and that this is likely a locally enhanced signature of the designated marker 1, and that said hard streak (sic) is what deflected us. This occurred 34' from the desired TD; as a result of this event, TD was called early."
  • 32894:
    • spud date: January 25, 2018
    • TD date: March 14, 2018
    • TD: 21,684 feet
    • target: Three Forks, second bench
    • vertical operations: two trips for MWD and two trips for motor & bit 
    • curve kicked off: January 29, 2019
    • final landing: 11,253' just inside the target top
    • Bakken shale collapse issues have been encountered in this region, and angles of intercept and shale exposure footage have become important data
    • description of drilling angle parameters provided
    • no shale collapse issues were encountered
    • drilled out of the shoe: March 11, 2018
    • only one trip was necessary; MWD tool failure
    • background gas: high -- trip gas hit 3,452 units; increase in gas as drilling continued suggested possibility of intercepting a natural fracture or possibly drilling into a localized stratigraphic trap
    • gas: common peaks exceeding 3,000 units; after the buster was deactivated, background gas averaged around 1,500 to 2,000 units
    • oil cuts were poor to fair, with the latter indicative of greater oil in the 2nd bench than previously experienced by these geologists
    • Mississippian Lodgepole: 10,255 feet
    • Mississippian Upper Bakken: 11,122 feet
    • Lower Mississippian-Upper Devonian Middle Bakken: 11,139 feet
    • middle Bakken: 33 feet thick
    • Upper Devonian Lower Bakken: 11,172 feet  
    • Upper Devonian Three Forks: 11,190 feet
    • the internal 1 shale top of the Three Forsk: 11,233 feet
    • Three Forks second bench: 11,244 feet
    • target: approx 13.5' thick, beginning 7.5' below the internal 1 shale base, and extending 21' below the same reference point
    • landing target angle was projected to be 14' below the internal 1 shale base, near the center of target

From the file report for #34094:
  • spud date: June 28, 2018
  • TD date: July 18, 2018
  • target: middle Bakken
  • to the KOP, with a planned trip in the Kibbey
  • curve build began, July 1, meaning the vertical took three days
  • drilled out of the shoe on July 15th; thus, three days to drill the lateral
  • low gas (generally 400 - 600 units)
  • slight flares, 1' to 3'
  • target would be approx 13' thick, beginning 13' below the middle Bakken top, and extending ot 26' below the same reference point
  • "almost entirely" within the target
