Abstract
A composition containing a quaternary organosilane foaming agent capable of foaming various liquids in order to remove the liquids from subterranean wells is described. For instance, the composition can be used to remove hydrocarbon condensate liquids from a gas well or an oil well. Of particular advantage, the composition can foam liquids containing substantial amounts of hydrocarbons.
