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

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.
