1. A method for collecting a heated fluid from a fractured subterranean formation, the method comprising:
removing, using a fluid removal system, 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, wherein the fluid removal system is shut down when a reservoir pressure is less than a saturation pressure of the fluid, and wherein a fluid injection system and a heated fluid collection system are shut down while the fluid removal system is removing the fluid comprising the liquid phase; and
collecting from the wellbore, using the heated fluid collection system after the fluid removal system is shut down, the 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 injection system and the fluid removal system are shut down while the heated fluid collection system is collecting the heated fluid comprising the vapor phase.
