  • DISPERSION OF WATER-SOLUBLE POLYMER FOR HYDRAULIC FRACTURING
    Publication number: 20240384159
    Abstract: An injection fluid for hydraulic fracturing including at least one synthetic water-soluble polymer with a weight average molecular weight greater than or equal to 1 million daltons, the fluid being prepared according to a method including preparing, by radical polymerization an invert emulsion including between 15% and 40% by weight of the polymer, between 20% and 60% by weight of water and at least one hydrocarbon-based solvent, distilling the invert emulsion to obtain a dispersion including between 40% and 60% by weight of particles of the polymer, less than 10% by weight of water and at least one hydrocarbon-based solvent, and diluting the dispersion with 1% to 15% by weight of an aqueous solution including between 20% and 60% by weight of salts.

  • Process for preparing an aqueous polymer dispersion under vacuum, and uses thereof
    Patent number: 9701831
    Abstract: Process for preparing an aqueous dispersion of hydrophilic polymers, according to which, in a reactor: a reaction medium is prepared in the form of an aqueous solution comprising water-soluble monomers, one or more salts and/or one or more dispersant organic polymers; the monomers are polymerized; the polymer obtained is discharged from the reactor; wherein the pressure of the reaction medium is lowered to a value below 200 mbar.
