Abstract: Surfactants constructed from three synthetic building blocks that contain multiple hydrocarbon chains, ethyleneamine, and alkyl sulfonate salt groups, were shown to possess good thermal stability, and foamability, and high foam profiles. The materials are targeted for high temperature foaming applications, such as foam flooding enhanced oil recovery to improve conformance control and other oil and gas downhole foaming applications.
