The well:
  • 34746, conf, Oasis, Nordeng 5298 13-25 8B, Banks oil field;
From the file report:
  • 12 miles northeast of Watford City, in McKenzie County
  • fifth of six wells to be drilled on the Mildred Nelson / Nordeng 5298 13-25 pad
  • will drill into sections 24/13-152-98;
  • spud July 30, 2018; cemented to 2,142 feet
  • re-entered on October 26, 2018 (same rig: Nabors B21)
  • curve successfully landed at 11,527' measured depth; 11,112' total vertical depth, 21' below the upper Bakken shale;
  • the lateral reached a total depth of 21,525' on November 3, 2018
  • October 26 - November 3: about eight days
  • upper Bakken shale: several gas sows exceeding 4,000 units
  • middle Bakken member (Mississippian-Devonian): entered at 11,345' MD, 11,091' TVD
    • background gases ranged from 500 to 3,500 units while several shows exceeded 5,000 units
    • wellbore remained with the target interval for "much" of the length of the lateral; to be exact, the wellbore was completed 98% withing the target interval;
    • chromatography of the middle Bakken revealed typical concentrations of methane, ethane, and propane characteristic of the middle Bakken
  • summary
    • drilled from surface casing to total depth in eight days
    • wellbore within desired target interval for 98% of the lateral; opening 10,015' for potentially productive reservoir rock
