INVERT EMULSIONS FOR WELL DRILLING COMPRISING POLYDIORGANOSILOXANES ABSTRACT This disclosure deals with a novel combination which is a composition of matter which is useful for well drilling operations and maintenance. The combination comprises an emulsifier composition comprising a solid, benzene-soluble organopolysiloxane resin copolymer; a hydrolytically stable compound having at least two organo- polysiloxane-polyoxyalkylene molecules crosslinked by a hydrolytically stable cross-linking radical; a polydiorgano- siloxane-polyoxyalkylene copolymer having at least one long chain alkyl group and at least one polyoxyalkylene group on the same molecule; and, a polysiloxane-polyoxyalkylene copolymer surfactant. Also disclosed are invert emulsions made with brine, hydrocarbon and the emulsifier combination and methods of making them.
