... these processes were recorded and in-situ saturation and pore-fluid occupancy maps were obtained at each cycle. During the first cycle, the proppant pack was first flooded with brine to establish 100% water saturation. This step represents the hydraulic fracturing stage before depletion takes place.

... differing production drivers for the Bakken and Three-Forks sweet spots. For the Three Forks, the key driver for the outperformance in the Nesson area is water saturation, with the critical threshold at 50%. For the Bakken, we see a more diverse set of production drivers. While the focus of this study...
