Combining geochemistry results with microseismic data helped identify...

... 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 is the Bakken play, the workflow presented here generalizes to other basins and other...
