FOAMED SCALE REMOVAL AND INHIBITION METHOD FOR SUBTERRANEAN FORMATION
Abstract:
A composition includes a nonionic fluorinated polymeric surfactant, a nonfluorinated surfactant, and a scale treatment. Additionally, a method for scale treatment is provided. The method includes injecting gas into the aforementioned composition to produce a foam and injecting the foam into a formation. In the formation, the foam may be exposed to a first temperature at which it has a first viscosity. The foam may be maintained inside the formation for a period of time, and then recovered from the formation, at which point it is exposed to a second temperature and has a second viscosity.
