A method of producing high water-cut gas via in situ water-disposal. Initially, a well is drilled and cased. The casing is perforated at an upper gas producing interval. Next, a tubing is run down through the casing and its lower end is perforated so as to fluidly communicate with a lower non-productive interval. The tubing is also perforated at a location below the producing interval and a production packer is placed between the casing's lower end and the tubing thereby forming an annulus. A slidable sleeve is positioned in the annulus to selectively open and close perforations on the tube side of the annulus. As gas is produced, water separated from the gas collects in the annulus and falls through perforations in the tubing where it is disposed of in the non-productive interval.
