Abstract: Geopolymeric compositions are presented that are useful for cementing subterranean wells. The compositions may contain an aluminosilicate source, a metal silicate, an alkali activator and a slurry density modifier that may contain uintaite, vitrified shale, petroleum coke or coal or combinations thereof. Methods for placing the geopolymeric compositions in subterranean wells are also presented.

Abstract: Geopolymer precursor compositions are presented that are useful for cementing a subterranean well, among other uses. The precursor compositions are dry mixtures that have an aluminosilicate source and an activator. The activator is an alkalinity source that is safe to store, transport, and blend with an aluminosilicate source. The activator may be a hydroxide-free activator. A geopolymer slurry is formed by adding water to the dry geopolymer precursor compositions. Such slurries have suitable characteristics for use in cementing applications that use pumpable mixtures.

Abstract: Cementing compositions contain water, a cement and an additive for adjusting thermal conductivity. The additive for adjusting thermal conductivity may be graphite, graphene, aluminum oxide, hematite, copper metal, copper oxide, aluminum, amorphous carbon, gallium metal, iron metal, magnesium oxide, nickel metal, nickel oxide, tin metal, tin oxide, zinc metal or zinc oxide, or combinations thereof. Such compositions may have thermal conductivities exceeding 2 W/mK. Such compositions may be useful in closed loop geothermal completions or for encasing electrical cables.
