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.
Claims19
A method for removing a liquid from a subterranean well, comprising:
- adding a composition to the liquid contained in the subterranean well, the composition comprising a quaternary organosilane foaming agent, the liquid comprising one or more hydrocarbons in an amount of at least 40% by weight of the liquid,
- combining the composition containing the quaternary organosilane foaming agent with the liquid in a manner that forms a foamed liquid within the subterranean well, wherein the foamed liquid contains the composition containing the quaternary organosilane foaming agent;
- and
- removing the foamed liquid containing the composition containing the quaternary organosilane foaming agent from the subterranean well.
