CORE ANALYSIS OF THE AMSDEN AND BROOM CREEK (PERMO-CARBONIFEROUS) FORMATIONS TO BETTER UNDERSTAND THE CARBON STORAGE POTENTIAL IN THE WILLISTON BASIN: GENERATING A STRATIGRAPHIC AND SEDIMENTOLOGICAL MODEL

The potential of the Broom Creek and Amsden Formations have yet to be fully understood. Previous analysis and models show high porosity and permeability in the aeolian and nearshore facies that commonly occur within the middle and upper parts of the formation (which currently function as a saline aquifer). The DOE, local and state agencies sponsored Project CarbonSAFE initiated by the EERC. Alongside the high porosity and permeability of the Broom Creek, the overlying siltstone and underlying anhydrite act as seals. Summit Carbon Solutions has obtained permits for pipelines in Minnesota and North Dakota, so the project will be more rapidly moving towards completion. Lacking data, since the formation hasn’t been exploited for hydrocarbons, the EERC oversaw the coring of Broom Creek. Analysis of four cores and a section of 3D Seismic modeling of the potential storage area will provide information to generate a stratigraphic and sedimentological model to better assess the carbon storage potential of Broom Creek.
