摘要

A method for increasing the water loss property of an aqueous suspension for use in wells containing an inorganic filler material, characterized by adding to said suspension an amount of a quaternary ammonium compound sufficient to make said material hydrophobic, said quaternary ammonium compound having the structural formula (NR4) χ TO wherein at least one of the R groups is an aliphatic radical having approximately 8 to 24 carbon atoms, the remaining R groups of lower aliphatic radicals and benzyl radicals being selected, A is an anion and χ is the valence of A.
