The invention provides for modified proppants, comprising a proppant particle and a hydrogel coating, wherein the hydrogel coating localizes on the surface of the proppant particle to produce the modified proppant, methods of manufacturing such proppants and methods of use.

Self-suspending proppants for hydraulic fracturing

The present invention provides modified proppants, and methods for their manufacture. In embodiments, the modified proppant comprises a proppant particle and a hydrogel coating, wherein the hydrogel coating is applied to a surface of the proppant particle and localizes on the surface to produce the modified proppant. In embodiments, formulations are disclosed comprising the modified particles, and methods are disclosed for using the formulations.

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.
