Abstract
Methods of continuously forming and suspending hardenable resin-fibrous material composite coated proppant in a carrier liquid are provided. The methods basically comprise dissolving a hardenable resin composition and a fibrous material in a solvent which is insoluble in the carrier liquid, pumping the carrier liquid, combining uncoated proppant with the carrier liquid as the carrier liquid is pumped and combining the hardenable resin composition-fibrous material solution with the carrier liquid as the carrier liquid is pumped whereby the proppant is coated with a hardenable resin composition-fibrous material composite.
