  • Oil recovery method utilizing a surfactant slug driven by water of a controlled salinity
    Patent number: 4250961
    Abstract: The efficiency of a low tension surfactant flooding program is improved by first determining the upper and lower boundaries for the range of injected water salinities, that, when intermingled with the injected aqueous surfactant slug will enable the surfactant to resist partitioning into an oil and/or emulsion phase and thereby continue to operate with maximum effectiveness. The water in the driving slug is formulated to fall within the specified salinity boundaries and is then injected at the appropriate time in the sequence of steps in the oil recovery operation.
