Abstract
A non-aqueous, non-flammable Group IVB metal alkoxide crosslinker composition includes a non-aqueous, non-flammable Group IVB metal alkoxide, wherein the metal is chemically bonded to a glycol containing 4 or more carbons, to an alkoxy group containing 6 or more carbons, or a mixture of both. A fracturing fluid employed in the hydraulic fracturing of subterranean formations is formulated through mixture of the non-aqueous, non-flammable Group IVB metal alkoxide crosslinker composition with a polymer solution.

A non-aqueous, non-flammable Group IVB metal alkoxide crosslinker composition comprising a non-aqueous, non-flammable Group IVB metal alkoxide, wherein the metal is chemically bonded to a glycol containing 4 or more carbons, to an alkoxy group containing 6 or more carbons, or a mixture of both.
A fracturing fluid, comprising:
- a non-aqueous, non-flammable Group IVB metal alkoxide crosslinker composition;
- and
- a crosslinkable polymer solution.
A method of hydraulically fracturing a subterranean formation, comprising:
- formulating a fracturing fluid, comprising:
- water,
- a polysaccharide, and
- a non-aqueous, non-flammable crosslinker composition comprising a non-aqueous Group IVB metal alkoxide;
- and
- pumping the fracturing fluid into the subterranean formation via tubing or casing to provide hydraulic force sufficient to initiate and propagate a fracture in the subterranean formation.
A method of hydraulically fracturing a subterranean formation, comprising:
- formulating a fracturing fluid, comprising:
- water,
- a polyacrylamide, and
- a non-aqueous, non-flammable crosslinker composition comprising a non-aqueous Group IVB metal alkoxide;
- and
- pumping the fracturing fluid into the subterranean formation via tubing or casing to provide hydraulic force sufficient to initiate and propagate a fracture in the subterranean formation.
