  • ULTRASONIC SOLUBILISATION OF SURFACTANTS FOR ENHANCED OIL RECOVERY
    Publication number: 20200063019
    Abstract: The invention concerns the solubilisation of surfactants suitable for enhanced oil recovery within an aqueous medium, by mixing said surfactants and the aqueous medium, carried out under ultrasound, advantageously to provide an over-concentrated solution that can be re-diluted with water available at the extraction site without impacting on the salinity of same. The invention also concerns the extraction fluids obtained according to this solubilisation technique and the use of same in EOR.
