Abstract: A method of enhancing heat transfer and energy efficiency in a geothermal reservoir includes injecting a carbonated fluid to the reservoir, injecting a first salt solution and a second salt solution into the reservoir, and increasing the temperature of the reservoir by reacting the first salt solution with the second salt solution to provide heat. The carbonated fluid injection decreases a temperature of the reservoir. The second salt solution is reactive with the first salt solution under the conditions in the reservoir after the injecting. A system of enhancing heat transfer and energy efficiency in a geothermal reservoir includes an injection system in fluid communication with an injection well. The injection system is configured to alternate the injection of the carbonated fluid and the first salt solution and second salt solution.
