Located right in the sweet spot of the Bakken.

Huge well for a Three Forks.

I was somewhat surprised to see the amount of ceramic used: 2.7 million lbs ceramic; 1.7 million lbs sand. My understanding is that in the short term, not much difference between sand and ceramic in effectiveness; long term ceramic much better. 

Geologist's comment:

• the lateral target zone of a ten (10) foot section of the Three Forks Formation situated 34 to 44 feet below the bottom of the Lower Shale of the Bakken Formation. The curve was landed .... approximately 34 feet below the Lower Shale of the Bakken Formation
• total background gas levels averaged ~975 units with common peaks ranging from ~1,400 to 1,800 units with rare peaks ranging from ~2,050 to ~2,160 units for approximately first 4,750 feet of the lateral section. Total background gas levels elevated ~1,650 units with common peaks ranging from ~2,200 to ~2,500 units during the remainder of lateral section.
