Regulating distribution of injection and production fluids to enhance heat recovery in geothermal applications

A method of improving heat recovery from a geothermal well, comprising:

• receiving temperature distribution data from a distributed temperature sensing (DTS) system comprising a fiber optic cable disposed in a wellbore, which extends through a formation;
• determining a location of a local maximum of flow rate in the wellbore based on the temperature distribution data;
• and
• injecting a sealing agent into the formation at the location, wherein the sealing agent cures to seal fractures within a fracture system in the formation at the location, and wherein the cured sealing agent prevents or mitigates fluid flow through the formation at the location.

A method of improving heat recovery from a geothermal well, comprising:

• receiving first temperature distribution data from a first distributed temperature sensing (DTS) system comprising a first fiber optic cable disposed in an injection wellbore, which extends through a formation;
• receiving second temperature distribution data from a second DTS system comprising a second fiber optic cable disposed in a production wellbore, which extends through the formation and is in fluid communication with the injection wellbore via the formation;
• determining a thermal efficiency profile between the injection wellbore and the production wellbore based on the first temperature distribution data and the second temperature distribution data;
• determining a location of a local minimum of the thermal efficiency profile;
• and
• injecting a sealing agent into the formation at the location, wherein the sealing agent cures to seal fractures within a fracture system in the formation at the location, and wherein the cured sealing agent prevents or mitigates fluid flow through the formation at the location.
