A geothermal aquifer is a natural underground layer of water-bearing rock that contains heated water, which can be used for geothermal energy production. These aquifers play a crucial role in the extraction of geothermal energy as they hold the thermal energy necessary for various applications, including heating and electricity generation. The efficiency and potential of geothermal aquifers are closely linked to their permeability and porosity, as well as the pressure and temperature conditions they maintain.
