Production of low permeability geothermal resources

A system for recovering thermal energy from a fractured subterranean formation, the system comprising:

• a fluid removal system configured to remove a fluid comprising a liquid phase from the fractured subterranean formation through a wellbore that is in fluidic communication with the fractured subterranean formation, wherein fractures within the fractured subterranean formation are in fluidic communication with a low permeability rock matrix, and wherein the fluid removal system is configured to be shut down when a reservoir pressure is less than a saturation pressure of the fluid;
• and
• a heated fluid collection system configured to recover, through the wellbore, a heated fluid comprising a vapor phase that is expelled from the low permeability rock matrix of the fractured subterranean formation as a result of a reservoir pressure of the fractured subterranean formation falling below a saturation pressure of the fluid, wherein the fluid removal system is configured to be shut down while the heated fluid collection system is collecting the heated fluid comprising the vapor phase, and wherein the heated fluid collection system is configured to be shut down while the fluid removal system is removing the fluid comprising the liquid phase.
