1. A heat extraction system for extracting heat from a reservoir, the system comprising:
a chemical processing unit configured to generate a working fluid;
a co-axial tool configured to be placed underground, the co-axial tool including an outer pipe and an inner pipe arranged within the outer pipe so as to define an annulus, the outer pipe and the inner pipe each being connected to a shoe to enable the working fluid to flow through the annulus, exchange heat with the shoe, and flow through a bore of the inner pipe; and
a power generator fluidly connected to the chemical processing unit so as to receive the working fluid, the power generator including a first port which fluidly connects to the inner pipe, and a second port which fluidly connects to the outer pipe,
wherein a temperature differential between the working fluid at the power generator and the working fluid at the co-axial tool drives the power generator to generate energy.
