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
