Isolation devices and flow control device to control fluid flow in wellbore for geothermal energy transfer

A method comprising:

• injecting fluid into a tubular of a wellbore formed in a geothermal formation for allowing the fluid to absorb geothermal energy, the wellbore including:
• a plurality of isolation devices positioned between a wall of the wellbore and the tubular to define one or more zones in the wellbore;
• and
• a flow control device positioned in the wellbore and between the plurality of isolation devices for controlling flow of the fluid between the one or more zones of the wellbore and for controlling flow of the fluid between the wellbore and the geothermal formation;
• a temperature sensor coupled with the flow control device, the temperature sensor positionable in the wellbore to provide temperature measurements for the flow control device, each zone of the one or more zones having a different potential for generating geothermal energy, wherein the temperature measurements are usable by the flow control device to identify a particular zone of the one or more zones having the highest potential for generating geothermal energy, the flow control device usable to selectively transport the fluid to a particular zone of the one or more zones with the highest potential for generating geothermal energy;
• directing, based on the temperature measurements and using the flow control device, the fluid between zones of the wellbore;
• extracting the fluid from a zone of the wellbore via the tubular of the wellbore;
• and
• generating usable energy with the fluid using an energy transfer device positioned at a surface of the wellbore.
