Fig. 2

Schematic figure of the tilted geopressured geothermal reservoir with one hot water producer well and one cold water injector well. The geologic systems dip at the angle θ. Three layers correspond to the upper colder layers of shale, the middle porous unconsolidated sandstone with high permeability, and the lower hot layers of shale. The natural convection takes cold fluid downdip and sends hot fluid updip. The injector helps create displacement of hot fluid updip
