Abstract
The problem of heat extraction by circulating water in a fracture em- bedded in hot dry rock is formulated as an integral equation solution. The mathematical model involves solving a heat transport equation in fracture and a heat diffusion equation in the infinite domain geothermal reservoir. The need to model the infinite domain is eliminated by the use of Green's function. Both two- and three-dimensional problems are formulated in this paper. Numerical implementation is given in two-dimension problems only. Introduction The hot dry rock (HDR) inside the earth can be an economical source of energy, owing to its large heat capacity. One of the methods for heat extraction in HDR is to
