Abstract: This article explores the possibility of harnessing geothermal energy from a single well in various geothermal settings by circulating water in a closed-loop system. The fundamental idea is to investigate, with an analytical approach, multiple independent variables that influence the fluid surface temperature, supporting the geothermal energy generation for various usages. This study proposes an analytical model involving the reverse circulation of water down the annulus and up the tubing to the surface.
