THE PROJECT IS DESIGNED TO SET UP AN EXPLORATORY WELL AND AN INNOVATIVE GEOIT SYSTEM FOR THE USE OF MEDIUM ENTHALPY GEOTHERMAL RESOURCES WITH THE ENVIRONMENTAL IMPACT PRESSSCH© O. ON THE BASIS OF THE TECHNICAL AND SCIENTIFIC KNOW-HOW OF THE GROUP WHICH IS PROPOSING, IT IS INTENDED TO PRODUCE A WELL IN A CARBONATE ROCKS AND TO INCLUDE A HEAT EXCHANGER IN ITS INTERIOR IN ORDER TO STUDY THE CONVECTIVE HEAT EXCHANGE BETWEEN THE CIRCULATING AND GEOTHERMAL HEAT EXCHANGE FLUID, WHICH WILL THEN BE RE-IMESED UNDERGROUND. THE HEAT EXCHANGE SYSTEM IN A WELL WAY WOULD MAKE IT POSSIBLE TO CONSTRUCT GEOTHERMAL PLANTS WITH VIRTUALLY NO IMPACT OR, FINALLY, TO REACH OUT DEFINITIVELY TO ALL POSSIBLE LOTS OF THE GROUND FOR THE GEOTHERMAL RESOURCE. THE EFFECTIVE USE OF HEAT EXCHANGERS IN THE POWER GENERATION WELL DEPENDS PRIMARILY ON THE SPEED OF THE SPREAD OF ROCK HEAT, AROUND THE WELL, WITH RESPECT TO THE SPEED OF HEAT REMOVAL.
