  • Foamed fluid compositions having high salinity using anionic surfactants and methods therefor
    Patent number: 9828815
    Abstract: An effective amount of at least one anionic surfactant may be present within a high salinity foamed fluid composition in an effective amount to generate an IFT as low as 10?3 mN/m. The anionic surfactant may be a sulfonate surfactant and/or a sulfate surfactant. The foamed fluid composition may be used to perform an operation, including but not limited to, a gas lift operation, a drilling operation, a completion operation, a stimulation operation, a fracturing operation, an injection operation, an enhanced oil recovery operation, and combinations thereof.
    Type: Grant
