Abstract
A method for reducing the water influx into a wellbore which penetrates a natural gas hydrocarbon-containing formation having a communication channel that extends from the wellbore into the formation and that is filled with proppant particles. In one embodiment, an aqueous particulate dispersion is introduced into the formation until a volume of the dispersion particles introduced is equal to or greater than one-half a water zone volume of the communication channel.
