A heat distribution model of an open geothermal system with multiple wells is considered. This system consists of two types of well: several production wells with hot water, which is used and became cooler, and an injection well, which returns the cold water into the productive layer (aquifer). This cold water is filtered in the productive layer (porous soil) towards the inflow of hot water of the production wells. A productive well network is considered for delivering hot water. In the paper the productive wells interaction is considered from the point of view the temperature in the wells optimization.
