Abstract
A water-free slurry may include a non-aqueous carrier fluid; a suspension agent including a mineral clay mixture; a crosslinking agent; and a hydratable polymer. A method of treating a subterranean formation may include injecting a water-free slurry into a wellbore penetrating the subterranean formation, the water-free slurry including: a non-aqueous carrier fluid; a suspension agent comprising a mineral clay mixture; a crosslinking agent; and a hydratable polymer.
