From the file report:
  • spud date: December 15, 2018; drilling operations begat at midnight of December 15, 2018 (sic -- no typo -- from the file report); H&P rig 535; normally takes about three days for the vertical section; 12 hours for the curve; no explanation for delay from December 18, 2018 to January 14, 2018; perhaps Christmas break; weather;
  • TD date: January 18, 2019
  • KOP: target of 11,438'; data (Upper Bakken Shale) suggested lowering it to 11,440' TVD; the change was communicated to the directional hands; the final ideal target at the Three Forks ended up being 11,439' TVD
  • collapse issues have been encountered in this region (previously posted, by the way)
    • discussion about best way to enter the shale
    • no shale collapse issues occurred
  • drilled out of the shoe early on January 14, 2019
  • discussion regarding drilling rates; geologist thought they were in ideal seam
  • gases extremely high; shoutout to the roughnecks preventing a blowout
    • background gases initially averaged 500 - 1,500 units; a couple of peaks exceeding 4,000 units, which brought in the gasbuster;
    • at 16,120' MD, gas increased to 1,500 - 2,000 units;
    • at 17,700' MD, gas levels rose to exceed 3,000 units and slowly built to 8,000 to 8,500 units from 20,000 - 21,000' MD
    • after this point, gas faded to a range of 4,500 - 6,000 units of background gas through to TD
  • further discussion regarding the seam and drilling rates
  • Markers:
    • base of last salt: 9,766'
    • Mission Canyon: 9,950'
    • Lodgepole: 10,474'
    • upper Bakken shale: 11,340'
    • middle Baken shale: 11,356' (so about 37' thick)
    • lower Bakken shale: 11,393'
    • Three Forks: 11,417'
    • KOP: 11,439' (so the curve about 341' in length)
    • horizontal segment, began at 11,780' MD
    • horizontal segment, TVD: 11,434.11 feet to 11,446.57 feet
  • assuming the wellbore was about mid-seam, the First Bench must have been about 12 feet thick;
