Grout fluids for use in a geothermal well loop
A method comprising (a) first, preparing a grout additive fluid comprising a fresh water base fluid and a grout additive control package comprising a primary additive selected from the group consisting of an inhibitor, a dispersant, a thermally conductive material, and any combination thereof, wherein at least about 90% of the dispersant and the inhibitor are dissolved in the fresh water base fluid; (b) second, introducing an aqueous swellable clay into the grout additive fluid, thereby forming a final grout fluid; and (c) third, introducing the final grout fluid into an annulus in a subterranean formation, the annulus formed between an exterior of a geothermal well loop tubular and the subterranean formation.
