Surfactants for EOR

˜Application

As oil displacement agent in oil recovery, Surfactants may be used alone, or combined with Alkali, Polymer for SP or ASP flooding for EOR.

˜Characteristic

Surfactants can reduce the oil/water interfacial tension to be 10-3-10-5mN/m , Anti high salt and temperature , promote the crude oil off from rocks and disperse effectively, displace residual oil and wash oil efficiency, enhance final oil recovery, convenient and safe usage.
