Discretization of domain into grid blocks. In the vertical direction, shown in a, there are a total of 106 grid blocks with dimensions ranging from 5.24 to 120.5 m (finest grid blocks are in the geothermal reservoir). In the horizontal directions, shown in b, there are 50 × 50 grid blocks. INJ refers to the injection point of the well and PROD refers to the production point of the well
