flow limit fluid composition, drilling fluid for use in underground formation drilling, hydraulic fracturing fluid for use in underground formation fracture, and use of a flow limit fluid composition

摘要

A stable, aqueous composition containing a crosslinked, nonionic, amphiphilic polymer capable of forming a yield stress fluid in the presence of a surfactant is disclosed. The yield stress fluid is capable of suspending insoluble materials in the form of particulates and/or droplets requiring suspension or stabilization.
