A method and system of controlling the temperature of fluids produced from a reservoir to prevent overheating of an adjacent geological formation. A cooling fluid is supplied through an annulus formed between a production tubing and a production casing, which are in fluid communication with the reservoir. The cooling fluid is mixed with the reservoir fluid, and the fluids are produced through the production tubing. The temperature of the produced fluids is controlled or reduced by heat exchange with the cooling fluid supplied through the annulus to prevent excessive heat dissipation to the geological formation.
