A high-thermal conductivity grout composition is provided. The composition includes a grout mixture including a cementitious material, a retarder, and a high-thermal k material that advantageously can form a pumpable slurry upon admixture with water. The retarder is present in an amount effective that delays setting of the grout mixture at a target location having a geostatic target temperature of at least 300° F. for at least two hours. The high-thermal k material is present in an amount effective such that the grout mixture has, upon setting at the target location, a thermal conductivity of at least 1 W/m° K.

High thermal coefficient grout compositions and methods therefor

Systems and methods for improved geoheat harvesting enhancements are presented in which a wellbore contains a closed loop geoheat harvesting system that is thermally coupled to a hot and dry rock formation via thermal reach enhancement structures that extend from the wellbore into the formation and that are filled with a thermally conductive filler. Preferred configurations and/or operational parameters are determined by a model that calculates heat flow in a three-dimensional system considering time changes and the influence of the thermal reach enhanced intrinsic thermal conductivity of the rock.

Geoheat harvesting enhancement

GeoHeat harvesting enhancement

A thermal reach enhanced geothermal wellbore has a plurality of fissures at a target location that distally extend into the formation and that are at least partially filled with a compacted high-thermal k material. The compacted high-thermal k material terminates on a proximal end of the fissure at the target location of the wellbore and is thermally coupled to a high-thermal conductivity grout or slurry through which heat is conducted to a working fluid that is contained in a closed loop working fluid conduit embedded in the grout or slurry.
