Geologic framework for the national assessment of carbon dioxide storage resources: Williston Basin, Central Montana Basins, and Montana Thrust Belt study areas

Using CO2-Plume Geothermal (CPG) Energy Technologies to Support Wind and Solar Power in Renewable-Heavy Electricity Systems

“…To characterize the CPG power plant model, we assumed that all CPG power plants were constructed so they use the Winnepegosis sedimentary basin geothermal resource, which underlies the area near Rugby. The Winnepegosis basin is large (i.e., 11-million acre formation with the potential to sequester 60 GtCO 2 ) and we assumed homogeneous subsurface reservoir properties of 3.05 km depth, 275 m thickness, 10 mD permeability, and a temperature of 117 ∘ C, based on a geologic temperature gradient of 35 ∘ C/km and a 10 ∘ C mean annual surface temperature [37].…”
