A heat transfer model of an open geothermal system is considered. This system consists of two wells: a production well 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 well. Some different boundary conditions for the model are compared in view to estimate effective thermal life of the system.
