Abstract
A grout composition includes a grout binder comprising calcium sulfate, the grout binder constituting from about 25.0 weight percent to about 99.0 weight percent of the grout composition, and at least one thermal conductivity additive comprising graphite. A grout formed from the grout composition has a thermal conductivity greater than about 1.0 W/m·K. Related grout slurries formed from the grout composition, grouts, and methods of grouting a wellbore are also disclosed.
