  • Calcium ion tolerant self-suspending proppants
    Patent number: 9932521
    Abstract: A self-suspending proppant comprises a proppant particle substrate carrying a coating of an anionic hydrogel-forming polymer. The detrimental effect of calcium and other divalent ions on the ability of the proppant to swell when contacted with water is reduced by including a calcium binding agent in the proppant.
