Resource Abstract

The Energy & Environmental Research Center (EERC) conducted a 3-month effort for the North Dakota Industrial Commission (NDIC) to investigate options to reduce flaring that could help to unlock curtailed oil production. The prime focus of this effort was to evaluate the feasibility of produced gas injection and storage into the Broom Creek Formation or other subsurface targets to help alleviate flaring where pipeline capacity is limited, including in both hydrocarbon-bearing and saline formations. Technical, economic, and regulatory aspects associated with injection of produced gas into the subsurface were assessed. A case study using the Broom Creek Formation, a saline saturated sandstone formation, was constructed to illustrate the concept and evaluate the formation’s potential as a produced gas storage target. Recognizing that the geologic extent of the Broom Creek does not include the northern portions of the core Bakken production area, alternative subsurface storage targets were also considered.
