Abstract:
1. A method of treating a subterranean hydrocarbon-bearing formation comprising unconsolidated or poorly consolidated particulates to produce a consolidated formation, the method comprising contacting the formation with a solution or a dispersion of an organosilane, wherein the organosilane is a silylated polymer of formula (I): wherein each R is independently a substituted or unsubstituted, alkyl group having from 1 to 6 carbon atoms, or a —C(O)R group where R is as hereinbefore defined; n is 0, 1 or 2; each A is a divalent organic radical; and B is a poly(oxyalkylene) linking group, a polyurethane linking group, or a poly(meth)acrylate linking group wherein the poly(oxyalkylene) linking group or the polyurethane linking group has a number average molar mass in the range of 600 to 20,000 g mol the residual matrix strength of the particulates is increased and their migration from the formation is reduced or prevented, the consolidation formation is flexible, and the consolidation formation maintains its permeability.
