Abstract
A composition and method for consolidating proppant or gravel for propping fractures about, or for gravel packs for sand control in, wells in subterranean formations characterized by an improvement in which there is used a combination of reactants, including a capped diisocyanate that will produce polyurethane and coat the catalyst in situ. Also disclosed are specific examples of satisfactory frac fluids, diluents and catalysts for both a specially designed one-pass system and, preferably, a two-pass system of putting and consolidating the proppant in a fracture.
