January, 2021: the lower Three Forks formation (third bench), Bakken-Three Forks petroleum system, overview of development history and future potential; Timothy O. Nehsheim, GeoNews, DMR, North Dakota, link to source article.
It appears there is some movement toward 1st bench / 2nd bench morphing into upper Three Forks, and 3rd bench morphing into lower Three Forks.
- sub-60% water-cut areas:
- 710,000 acres
- 550 "standard" 1280-acre drilling units
- three horizontal wells per spacing unit = over 1,600 horizontal lower Three Forks wells (~ 3rd bench wells)
- sub-70% water-cut area
- 1,600,000 acres
- more than double that of just the sub-60% water-cut areas
- potential: several thousand wells
