Abstract

This work investigated multiple mechanisms that can potentially lead to H₂S in the oil production stream of Bakken wells, including TSR, BSR, source rock generation, migration from deeper or shallower formations that contain H₂S, and geomechanical mechanisms related to reservoir stimulation work.
