  • Method of improving cleanout of a wellbore
    Patent number: 9506317
    Abstract: A barrier onto the surface of a subterranean formation may be formed by pumping into a wellbore within a well hydrophobically modified polysaccharides. A pressure differential is created between the reservoir pressure and formation pressure within the well. The micellular hydrophobically modified polysaccharides self-align onto the face of the formation to form the barrier. Flow of fluids into the subterranean formation is thereby prohibited.
    Type: Grant
