Abstract
A method for treating a gas well to prevent any fresh water, which may have condensed out of the gas stream, from damaging the gas producing formation during the shut-in period. The well is shut-in and then an additive, e.g. a salt, alcohol, etc., is injected into the well to convert any accumulated fresh water into an aqueous solution which will not damage the formation. The additive can be injected in solid form or as a solution.
