ABSTRACT:
A method for reducing the amount of liquids produced from a selected geologic formation of a gas producing well is disclosed. A solution comprising controlled quantities of a scaling cation brine and scaling anion brine such that a scale will precipitate, and a controlled quantity of a scale inhibitor such that the scale precipitation will be delayed, is injected into the formation. The well is then shut-in long enough to allow the injected mixture to precipitate scale and to reduce the permeability of the formation such that a substantial portion of liquids that had been produced before, no longer are produced upon a resumption of gas production.
