| titleOfInvention | Crosslinked fluid treatment and methods for fracturing underground formations based on flowback, production water, seawater, fresh water, and mixtures of same |
| abstract | The present invention provides cross-linked fracture fluids that allow for reusing return water with no treatment, minimizing the environmental impact thereof and reducing the use of fresh water to very low levels to stimulate wells or re-stimulate wells stimulated in the past. Preparation and use methods of said fluids in fractured subterranean formations drilled by wells, based on return water, production water, sea water, fresh water and mixtures thereof, are provided. Fluids are basically composed of: return water, production water, sea water, fresh water and mixtures thereof present in a sufficient amount to moisten the gelling agent and to form a gellified aqueous agent; a gelling agent; an iron control agent; an alkaline buffer; a delayed cross-linking agent, and a rupture system to "break" the fluid and improve fracture cleaning. |
