1. A method of fracturing a portion of a subterranean formation using proppant prepared on-the-fly comprising:
placing a treatment fluid into a well bore penetrating a subterranean formation at a pressure sufficient to create or enhance a fracture in a portion of the subterranean formation;
providing discrete amounts of a resin mixture that comprises a resinous material and a filler material, wherein the resin mixture comprises from about 5% to about 90% filler material by weight, and wherein the discrete amounts of the resin mixture comprise a plurality of filler material particles;
placing the discrete amounts of the resin mixture into the well bore containing the treatment fluid; and,
allowing the discrete amounts of the resin mixture to substantially cure and form proppant particles while inside the treatment fluid.
