Abstract

Proppant particles coated with a resin system containing a reactive resin and an organopolysiloxane having at least three successive siloxy units and at least one pendent or terminal group which contains at least four atoms selected from C, N, P, O, and S, exhibit higher degrees of coating and decreased fracture and release of fines at high pressure, thus enhancing fracking performance.
