US Classification:

507203, 507239, 507240, 507252, 507266, 507269, 507267, 507277, 507921, 507922, 1663082, 1663083

Abstract:

Methods and compositions are disclosed for controlled addition of components that decrease the viscosity of the viscoelastic surfactant fluids or for controlled changes in the electrolyte concentration or composition of the viscoelastic surfactant fluids. One aspect of the invention relates to the use of internal breakers with a delayed activation. Another aspect of the invention relates to the use of precursors that release a breaking system such as alcohol by a process such as melting, slow dissolution, reaction with a compound present in the fluid or added to the fluid during or after the step of injecting, rupture of an encapsulating coating and de-adsorption of a breaking agent absorbed into solid particles. In another aspect of the invention, alcohols are included in a pad to reduce the low-shear viscosity and reduce the resistance to flow of the treatment fluids during a desired phase of the treatment.

US Classification:

1663051, 16625001, 1662501, 703 10, 703 12

Abstract:

Subterranean formation treatment methods incorporating a rheology model which enables prediction of fluid rheology properties during a treatment operation, where the foundation of the model is a description of the reaction chemistry which describes how the number of crosslinks and broken polymer linkages develops in time under the influence of crosslinkers, breakers, and/or thermally induced effects and pressure effects. In one aspect, when used as a tool for simulating the fluid viscosity, the model can help optimizing the fluid design and optional breaker schedule for a hydraulic fracturing treatment.

International Classification:

C09K 8/86

US Classification:

507237, 507244

Abstract:

Disclosed are compositions and methods for treating subterranean formations, in particular, oilfield stimulation compositions and methods using polymer viscosified fluid crosslinked with metal complexes with amino and/or phosphonic acids to provide an increased crosslinking temperature and a low pH sensitivity. The metal complexes can be used with borate crosslinkers to provide continuous viscosification as the temperature is increased.

International Classification:

C09K 8/68

US Classification:

507209, 507219

Abstract:

A method of treating a subterranean formation penetrated by a wellbore is carried out by providing a treatment fluid comprising a hydratable polymer, a divalent metal salt in an amount of at least about 0.25 mol/L and an aluminum crosslinking agent. The fluid is provided with a pH of from about 5 or higher. The treatment fluid may be caused to contact the formation by introducing the fluid into the wellbore. The fluid may optionally contain a polyol.
