Zusammenfassung:	TREATING WELLS WITH NON-BUOYANT BALL SEALERS In the treatment of the producing zones of a well to enhance the flow of produced liquids, ball sealers having a specific gravity greater than the produced fluids are suspended in a viscous fluid having substantially the same specific gravity as the ball sealers. The viscous fluid, with the ball sealers suspended therein, are supplied to at least one of the zones of the well to seat the ball sealers in the perforations in the casing and cement sheath thereby diverting fluid flow from that zone while another zone of the well is being treated.
