Map of the general area:



From the file report for #26833:
  • the Three Forks Formation (Devonian) was reached at 10,982 feet
  • the Three Forks first claystone unit was reached at 11,038 feet
  • the Three Forks second bench (Devonian) was reached at 11,080 feet
  • the target zone of the Three Forks was to be drilled in a predominately dolomite thirteen foot zone beginning 13 feet into the Three Forks second bench
  • low gas pressures in the target zone, with background ranging from 100 to 150 units; connection peaks of 170 to 330 units
From the file report for #26130:
  • the Upper Bakken Shale member (Mississippian-Bakken Formation) was drilled at 10,952 feet; hydrocarbon in this interval reached a maximum of 572 units with a down time gas of 5,931 units
  • the Bakken Middle Member (Mississippian-Devonian) was reached at 11,006 feet; 
  • the target zone of the middle Bakken was to be drilled in a predominately silty sandstone eleven foot zone beginning 14 feet into the middle Bakken
  • gas shows were very high, with trip gases of 5,268; 6,046; 4,666; and 4,621 units respectively
  • opened 10,131' of potentially productive reservoir rock
From the file report of #19844:
  • the third well in a series of wells by Oasis targeting the Three Forks in this area
  • the Bakken Formation was penetrated at 10,827 feet
  • the Middle Bakken at 10,855 feet; 
  • the Lower Bakken Shale was penetrated at 10,922 feet, geology similar to Upper Bakken Shale
  • true thicknesses for the Bakken members are as follows: Upper Bakken, 19 feet; middle Bakken, 40 feet; and, the Lower Bakken Shale, 12 feet
  • the Three Forks Formation was drilled at 10,945 feet
  • background gas generally low, peaking at 739 units; trip gas as high as 774 units
  • well bore maintained with the 25-foot thick target interval for 79% of the total exposed well bore
