Eddins, Jr, W N; Lissant, K J

The porosity or permeability of a subterranean formation can be reduced by injecting into the formation a fluid which is immiscible with the connate fluids. The injected fluid contains a surface-active material capable of emulsifying the connate fluid to form a viscous emulsion. This method can be used to shutoff water in air or mud drilling wells, producing wells, and injection wells. The following uses have been found for this sealant: improving injection profile, sealing off high GOR formations, sealing formations subject to in-situ combustion, plugging wells, and preventing water intrusion into mines or excavations.
