  • ADDITIVES FOR ELIMINATING FRACTURING FLUIDS USED FOR OIL EXTRACTION
    Publication number: 20200208043
    Abstract: The invention relates to a method for extracting a crude oil contained in a geological formation, which comprises a step of fracturing said geological formation, by injection of a specific aqueous extraction fluid under pressure, which contains at least one surfactant that reduces the interfacial tension between the extraction fluid and the crude oil to be extracted to below 0.1 mN/m; followed by a discharge step (“flowback”). The invention likewise relates to the original fracturing fluids used in this method, and the additives used in these fracturing fluids.
