Foam-Lift Systems
Foam-lift systems alter the physical properties of the produced fluid by applying surfactant. Surface tension and apparent liquid density are altered to reduce the critical velocity needed to lift the water from the system. The surfactants react with water, so application is effectively limited to wells in which most of the liquid phase is water rather than hydrocarbon. Foam-lift systems excel in deliquification of low-reservoir-pressure wells that need to be continuously produced to high line pressures and when tubing restrictions or tapered strings hamper plunger-lift application.
