Breaking compositions are disclosed for controlled breaking of borate cross-linked fracturing fluids, and to method for making and using same, where the composition includes an oxidative component and an ester component.

Compositions and method for breaking hydraulic fracturing fluids

Gelled organic compositions and methods for using same. The gelled compositions may be liquid organic fluids, such as gelled liquid hydrocarbons, formed from a mixture of an organic-base fluid, a carboxylic acid, and one or more metal source compounds, such as a metal salt of carboxylic acid. The gelled compositions may be used in variety of applications including, but not limited to, oil field, pipeline and processing facility applications.

Gelled hydrocarbon compositions and methods for use thereof

Compositions comprising a base fluid and a monoester copolymer of styrene and maleic anhydride are disclosed. The compositions can further comprise an alkyl orthophosphate ester. The base fluid can be an aqueous or organic base fluid. The monoester copolymer is at least partially soluble or dispersible in the base fluid. Preferably, the composition may further include a cross-linking agent capable of increasing the viscosity of the composition, such as aluminum isopropoxide or other metal source compounds. The composition can form a gel which is stable at a temperature of about 250&deg; F. (121&deg; C.) or higher. Some gels of the present invention exhibit stability up to about 300&deg; F. (149&deg; C.) to 350&deg; F. (177&deg; C.) or higher. The compositions have many applications, such as pipeline treatment, conformance, hydraulic fracturing, well completion, gravel packing, drilling fluids, process facility treatment fluids, and other well treatment applications.
