Abstract:
Method of fracturing a subterranean formation by injecting an aqueous fracturing fluid comprising an aqueous base fluid, a polysaccharide and/or polysaccharide derivative, a crosslinker, which is a water-soluble, layered silicate and a proppant. Aqueous fracturing fluid comprising an aqueous base fluid, a polysaccharide and/or polysaccharide derivative, a crosslinker, which is a water-soluble, layered silicate and a proppant and to the use of water-soluble, layered silicates as crosslinker for aqueous fracturing fluids comprising polysaccharides and/or polysaccharide derivatives.
