Abstract: A heat extraction system for extracting heat from a reservoir, the system including a co-axial tool configured to be placed underground, the co-axial tool having an outer pipe and an inner pipe located within the outer pipe, each of the outer pipe and the inner pipe being connected to a shoe so that a fluid flows through an annulus defined by the inner and outer pipes, reaches the shoe, and flows through a bore of the inner pipe; and a power generator fluidly connected to a chemical processing unit to receive a fluid, and also fluidly connected with a first port to the inner pipe and with a second port to the outer pipe of the co-axial tool. A temperature difference of the fluid at the power generator and at the co-axial tool drives the power generator to generate energy.
