Well treating fluid

Patent ·
OSTI ID:5992010
This patent describes a heterogeneous well treating shear thickening composite comprising at least 10 weight percent of a water-swellable material capable of rapidly forming a high strength paste when mixed with water, an oil-surfactant phase and substantially polymer-free water. The water-swellable material is present in sufficient quantity so as to form a paste having a strength of at least 2000 lb/100 ft/sup 2/ and the water are kept separated by the intervening oil-surfactant phase until application of a shear force sufficient to cause mixing of the water-swellable material and the water.
