Completion Strategy For Hess In The Tioga Oil Field -- November 15, 2020


November 16, 2020: a reader who follows this much more closely than I do and who understands this much better than I do had this to say about this well:

It is very good to see you tracking the particulars of this drilling and completion stuff as these ongoing improvements will continue to play big roles in lowering the cost of producing US hydrocarbons.

Combining the reduced  cost/time to D&C wells with the ever increasing recovery rate is actually greatly expanding the footprint for economically  viable development.

For some  comparison, Range Resources - I believe - drilled about a 10,500 foot lateral in under 24 hours and Antero did a now-record 11,300+ foot in a 24 hour time span. 
Truly remarkable performances ... especially when one realizes that they are staying in zone about 100% of the time.

This well is coming off the confidential list this next week:

  • 7211, conf, Hess, TI-Nelson-157-94-3031H-1, Tioga,
DateOil RunsMCF Sold

Completion strategies tracked here.
  • fracked 4/6/20 - 4/17/20: 10.8 million gallons of water, a large frack for the Bakken these days; 89.3% water by mass;
NDIC file report:
  • spud: January 20, 2020
  • cease drilling: January 29, 2020; 2:57 p.m. CT
  • TD: 20,478' MD
  • middle Bakken target
  • vertical: drilled in two runs with a planned bit trip occurring at 7,642' MD
  • KOP reached at 9,480' MD, 1:45 p.m. CT, January 24th, 2020
  • curve: drilling commenced at 10:51 p.m. CT January 24, 2020; completed curve at 10,302' MD at 10:11 a.m. January 25, 2020 (again, the standard for drilling the curve in the middle Bakken is about twelve hours; I've seen it done in as few as three hours;
  • upper Bakken: gas ranged as high as 2,234 units
  • middle Bakken: gas ranged as high as only 808 units
  • lateral:
    • 20' target window was centered 26" below the top of the middle Bakken, so a seam about 52' thick?
    • began: January 26, 2020; 11:02 p.m. CT -- just before midnight
    • completed: January 29, 2020: 2:57 p.m -- just after noon
    • so, is that about 2.5 days to drill the lateral?
