  • Patent number: 10000683
    Abstract: Crosslinked sulfonate-containing polymers may be stable in high density, monovalent brines, which may render such polymers particularly useful in drilling fluids in general and, especially, in the subclass of drilling fluids known as drill-in fluids. For example, a drilling fluid may include a crosslinked sulfonate-containing polymer dispersed in a monovalent brine having a density of about 8 lb/gal to about 20 lb/gal, wherein the crosslinked sulfonate-containing polymer comprises: reactants of a first repeating unit and a crosslinker that react to form the crosslinked sulfonate-containing polymer, wherein the first repeating unit is a sulfonic acid-containing monomer present from 50% to 99.99% by weight of the reactants, and wherein the crosslinker comprises at least two olefinic bonds.
