Definition - What does Geothermal Reservoir mean?
Geothermal Reservoir is the volume of rocks in the subsurface region. It is one of the best ways to generate electricity using wells. High temperature, working fluid and permeable flow channels are some important elements of Geothermal Reservoirs. The reservoir is dynamic in nature and possesses heat from underground to exploitable depths. It provides a deep understanding of fluid mass and heat which take place in natural conditions due to production operations.
Petropedia explains Geothermal Reservoir
It is important to note that production of heat is necessary for transporting fluids and for drilling purposes, thus Geothermal Reservoirs play an essential role in the oil and gas industry. A reservoir model provides a conceptual picture of the Geothermal Reservoir. It is incorporated with locations, discharge and recharge areas, diverse rock properties, porosity and the extent of permeability. 360 degree Celsius is the maximum temperature encountered in geothermal wells. The two types of Geothermal Reservoirs are unconventional and conventional reservoirs. Most of the Geothermal Reservoirs are found in fractured volcanic rocks and discrete fractures.
