Abstract
Fracturing fluid compositions and methods for their preparation and use are disclosed. The compositions are useful in the oil and gas drilling operations, as well as in gravel packing operations, water blocking, temporary plugging for purposes of wellbore isolation and/or fluid loss control, and other uses. The compositions comprise a liquid, a polymer soluble in the liquid, having a degree of substitution of ionic groups of about 0.01 to about 0.1; and a crosslinking agent capable of increasing the viscosity of the fracturing fluid by crosslinking the polymer in liquid.
Claims30
A fracturing fluid comprising:
- a liquid;
- a polymer soluble in the liquid, having a degree of substitution of ionic groups of about 0.01 to about 0.1;
- and
- a boron crosslinking agent or an antimony crosslinking agent, capable of increasing the viscosity of the fracturing fluid by crosslinking the polymer in liquid.
A method of treating a subterranean formation, the method comprising:
- obtaining a fracturing fluid comprising a liquid, a polymer soluble in the liquid, having a degree of substitution of ionic groups of about 0.01 to about 0.1, and a boron crosslinking agent or antimony crosslinking agent, capable of increasing the viscosity of the fracturing fluid by crosslinking the polymer in liquid;
- and
- injecting the fracturing fluid into a bore hole to contact at least a portion of the subterranean formation.
