Abstract

The instant invention is directed to shear thickening fluids which comprise a water swellable clay capable of rapidly forming a paste having a strength of at least 2000 lbs/100 ft.sup.2 upon interaction with the aqueous phase employed and present in sufficient concentration to form such a paste, a nonaqueous phase comprising a hydrocarbon material and surfactant, and an aqueous phase comprising water and a water-soluble polymer, wherein the clay and the aqueous phase are kept separated by the intervening hydrocarbon-surfactant phase. The intervening oil phase prevents the interaction between the water-polymer phase and the clay and results in a stable, non-reacting, pumpable composite, until such time as the oil barrier is ruptured by deliberate application of a sufficiently high shear force. Upon such rupture, the materials interact resulting in a semi-rigid high strength paste.
