Geopressured Geothermal Systems

Sedimentary Geothermal Systems:
Sedimentary Geothermal Systems produce electricity from medium temperature, high flow rate geothermal reservoirs in large-basin, sedimentary deposits.

Geopressured Resources are found when there is an impermeable layer of sedimentary cap rock that traps a geothermal reservoir. In these instances the weight of the sediment layer and the lack of permeability increases the pressure inside of the reservoir. Geopressured resources typically range from 90°C to 200+°C, and the increase in pressure reduces the energy required to pump the resource making geopressured resources desirable. In the United States geopressured resources can be found along the Pacific coast, in Appalachia, beneath the Gulf of Mexico, and in other deep sedimentary basins.[1]
