In prior work, we compared power generation estimates between sedimentary basin power plants using CO 2 as a subsurface heat extraction fluid versus water for a few different scenarios of subsurface conditions. In this study, we use genGEO to expand the parameter space across which we make this comparison by finding the generation for 5,000 unique combinations of reservoir depth (between 1 km and 7 km) and transmissivity (between 100 and 10,000,000 mD-m). Transmissivity is the product of reservoir thickness and permeability (1 mD-m = 10 -15 m 3 ). All scenarios assume a 35 °C/km geologic temperature gradient and one inverted 5-spot well pattern power plant.
