BIOPOLYMER BASED CATIONIC SURFACTANT FOR CLAY STABILIZATION AND PREVENTION OF SLUDGING

摘要

Methods of stabilizing swellable clays in a subterranean formation and methods of reducing the formation of sludge in a subterranean formation using a biopolymer based cationic surfactant are described. The biopolymer based cationic surfactant includes a quaternary ammonium compound having an alkyl polyglucoside backbone and amino alcohol side chains.
