摘要
This disclosure provides compositions comprising a suspension package, wherein the suspension packaging consists of solids for suspending in one or more liquids, wherein the solids comprise at least one of: (1) diamond dust, nano-diamonds, or combinations thereof; (2) tungsten; (3) graphite, graphene, or combinations thereof; and (4) silicon carbide. Further, 0.25% through 6% by volume of the composition, with the one or more liquids being present, in a 14.0 ppg aqueous CaBr2 solution, provides a coefficient of friction of less than 0.06 at a temperature between 250° F. and 400° F. at any time up through 10 minutes after combination of the 0.25% through 6% by volume of the composition to the 14.0 ppg aqueous CaBr2.
