At least one wellhead 18 upstream of a thermoelectric generator (TEG) 26 conveys a flow of warm fluid from a subterranean source 16 to the generator. The wellhead can be connected to at least one other wellhead (40 Fig. 1) downstream of the generator, and fluid flows from the subterranean source via the first wellhead and the TEG to the at least one other wellhead and back to the source (16 Fig. 1).

Closed loop wellbore configurations with unrestricted geometry for accommodating irregular or challenging thermal gradients within a thermally productive formation are disclosed. A working fluid is utilized in the loop for extraction of thermal energy there from. The loop and the unrestricted geometry are achieved using magnetic ranging of independent drilling operations which intersect from an inlet well and outlet well to form an interconnecting segment. In conjunction with the directional drilling, conditioning operations are incorporated to condition the rock face, cool the entire system, activate the wellbore for treatment to optimize thermal transfer inter alia. The significant degree of freedom in wellbore configuration is further optimized by the absence of mechanical impediments such as casing or liners in the heat transfer areas.
