Slide 8 is particularly interesting for many reasons. The graphic shows the average EUR among ten (10) subdivisions in the Bakken, based on township boundaries. The average EURs (in 1,000's; 2010 to 2011):
- Sanish Parshall: 632
- Ft Berthold: 569
- Bear Den: 536
- South Nesson: 506
- Rough Rider: 466
- Bailey: 459
- Elm Coulee (Montana): 433 (2001 - 2003 data)
- North Nesson: 393
- Mondak: 283
- St Demetrius: 209
The data on number of frack stages vs those subdivisions seems to be inconclusive.
Data regarding type of proppant used:
- Sand: 614 wells
- Sand and ceramic: 78 wells
- Ceramic only: 74 wells
Based on a very limited data set, a mixture of 2/3rds sand and 1/3rd ceramic appears more effective than either along.
The maturity boundary of the Bakken/Three Forks:
The maturity boundary of the Bakken/Three Forks:
- northern boundary: eastern half of Divide County
- eastern boundary: splits Mountrail County in half; diagonally splits Dunn County in half
- southeastern boundary: includes the western third of Stark County
- western boundary: well into Montana; off of Williams, McKenzie, Billings, and Golden Valley counties inside the boundary limits
Slide 19 is one of the more interesting slides: graphic depicting oil / oil + water.
Slide 20 is also interesting: the sweet spots / uneconomic spots tend to correlate with oil / oil +water.
Slide 22 should satisfy mineral owners to the east of Williston and explain why Stockyard Creek has been such a good field. Epping field should also be a great field.
Slide 23: back to oil / oil +water. Elm Coulee ≠ Bear Den ≠ Rough Rider.
