The present invention relates to methods for making proppants on-the-fly
during subterranean treatment operations. Some embodiments of the present
invention provide methods of preparing proppant on-the-fly comprising
providing discrete amounts of a resin mixture that comprises a resinous
material and a filler material; placing the discrete amounts of resin
mixture into a well bore comprising a treatment fluid; and, allowing the
discrete amounts of the resin mixture to substantially cure and form
proppant particles while inside the treatment fluid. Other embodiments of
the present invention provide methods of fracturing a portion of a
subterranean formation using proppant prepared on-the-fly.
