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

A high-thermal conductivity slurry composition is contemplated that includes a slurry mixture comprising a high-thermal k material, water, and an optional dispersant. Preferably, the high thermal k material is in the form of a plurality of particles having a wide size distribution that spans across at least 2 log units and is present in an amount effective such that the slurry composition has, upon compaction or settling of the slurry mixture at a target location, a thermal conductivity of at least 3 W/m° K.

High thermal coefficient slurry compositions and methods therefor

Thermal energy is extracted from geological formations using a heat harvester. In some embodiments, the heat harvester is a once-through, closed loop, underground heat harvester created by directionally drilling through hot rock. The extracted thermal energy can be converted or transformed to other forms of energy.

Geothermal heat harvesters

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.

Systems and methods for thermal reach enhancement

An apparatus and method for the hot water treatment of debarked logs to eliminate infestation and fungi in the logs is presented. The present invention utilizes a water tank and a heat generation source to raise the temperature of the center of the logs above a predetermined level for a sufficient time to accomplish this purpose.
