Formulations of alkaline surfactant polymer without to recover crude oil reactive

摘要

Formulations of alkaline surfactant polymer without to recover crude oil reagent. Compositions and methods for oil recovery using a system of alkaline surfactant polymer without in heavy water or brine heavy are described in this invention. The formulation also includes a chelating agent, an alkylating agent (which may be the same as the chelating agent), and U. M co solvent.The formulations as disclosed here are capable of forming a surfactant in situ resulting in microemulsions Winsor type III of interfacial tension is low.
