Compositions and methods for breaking hydraulic fracturing fluids

A method for maintaining a reduction in viscosity of an aqueous treatment fluid, said method comprising:

• combining an aqueous non-emulsified breaker composition with the aqueous treatment fluid,
• wherein the aqueous treatment fluid comprises at least one gelling agent and at least one crosslinking agent,
• wherein the aqueous non-emulsified breaking composition comprises water;
• at least one water soluble organic peroxide which is tert-butyl hydroperoxide, and at least one alcohol selected from the group consisting of propylene glycol, a butyl alcohol, a monosaccharide, a disaccharide and a combination thereof,
• wherein the aqueous non-emulsified breaker composition reduces the viscosity of the aqueous treatment fluid at a temperature of 90-300° F., and
• wherein the aqueous non-emulsified breaker composition maintains a reduced viscosity of the aqueous treatment fluid for a period of time after the temperature is reduced from 90-300° F.

A method for fracturing a subterranean formation comprising:

• injecting into the subterranean formation under fracturing conditions an aqueous treatment fluid and an aqueous non-emulsified breaking composition,
• wherein the aqueous treatment fluid comprises a gelling agent and a crosslinking agent,
• wherein the aqueous non-emulsified breaking composition comprises water;
• at least one water soluble organic peroxide which is tert-butyl hydroperoxide, and at least one alcohol selected from the group consisting of propylene glycol, a butyl alcohol, a monosaccharide, a disaccharide and a combination thereof,
• wherein the aqueous non-emulsified breaker composition causes the aqueous treatment fluid to have a reduced viscosity at a temperature of 90-300° F., and
• wherein the aqueous non-emulsified breaker composition causes the aqueous treatment fluid to maintain a reduced viscosity for a period of time after the temperature is reduced from 90-300° F.
