Treatment Fluid fracturing crosslinked and Methods of underground formations based on return Water, Production Water, sea Water, Freshwater, and mixtures thereof

摘要

The present Invention provides cross-linked fracturing Fluids to allow the reuse of return water without any treatment, Minimizing the Environmental Impact of the very low levels and reducing the use of fresh water to stimulate New Wells or Wells which re stimulate Sides in the past.Methods are provided for Preparation and use of these Fluids in underground formations penetrated by fracturing Wells based on return Water, Production Water, sea Water, Freshwater, and mixtures thereof.The Fluids are basically composed of: Return Water, Production Water, sea Water, fresh water or mixtures thereof in an amount sufficient to hydrate and a Gelling Agent to form a gelled aqueous Fluid; Gelling agent; a control Agent of Iron; Alkaline buffer; a cross-linking Agent delayedAnd a system Breakdown to "Break" The fluid and improve the cleanliness of the Fracture
