    摘要: Grout fluids, methods of preparing the grout fluids, and methods of using the grout fluids are provided. The methods of preparing the grout fluids include providing a thermally conductive material in a plurality of particle sizes, formulating a grout fluid including each particle size of the plurality of particle sizes of the thermally conductive material, determining permeability for each formulated grout fluid, identifying a particle size range of the thermally conductive material that provides a permeability of less than 1×10−7 cm/s as measured by ASTM procedure D5084, and preparing a grout fluid including the thermally conductive material having the identified particle size range.

    摘要: A subterranean grouting method comprising (a) placing a sample of a grout mixture within a test container, (b) separating a sand component from the sample, (c) determining if the grout mixture exhibits a thermal conductivity within a predetermined thermal conductivity threshold based upon a proportion of the sand component within the sample, and (d) upon determining that the grout mixture exhibits a thermal conductivity with the predetermined thermal conductivity range, securing a conduit within a subterranean bore with the grout mixture, wherein (a), (b), (c), and (d) are carried out proximate each other at a job site.
