Abstract:
Self-suspending proppants including proppant particles coated with a CO 2 -philic coating are provided. The CO 2 -philic coating may be lightly crosslinked and may have a physical structure that constrains CO 2  molecules. Methods of making self-suspending proppants may include coating a proppant particle with a polymerizable precursor material of a CO 2 -philic material and polymerizing the polymerizable precursor material to form a self-suspending proppant are also provided. Additionally, hydraulic fracturing fluids that may include a CO 2 -based fluid and the self-suspending proppants and methods of treating subterranean formations by contacting a subterranean formation with hydraulic fracturing fluid and propagating at least one subterranean fracture are provided.

Claim (Index 1):
A method for producing self-suspending proppant particles, the method comprising:\n coating proppant particles with a polymerizable precursor material of a CO 2 -philic material to form coated proppant particles; and polymerizing the polymerizable precursor material to convert the coated proppant particles to self-suspending proppant particles coated with the CO 2 -philic material in which the CO 2 -philic coating is lightly crosslinked and has a physical structure that constrains CO 2  molecules.
