Method of consolidating porous formations using vinyl polymer sealer with divinylbenzene crosslinker
A method and a composition are described for consolidating an unconsolidated subterranean formation into a high strength water resistant mass. The composition is a particular combination of vinyl monomers, catalyst system, and optional features such as solvent, particulate filler, chelates, and binders. Examples of preferred vinyl type monomers are styrene, acrylic acid, methacrylic acids, acrylonitrile, methacrylonitrile, divinylbenzene, and their mixtures. For low temperature applications, acrylic acid or acrylonitrile monomers should be present. When conventional preflushes and afterflush phases are used to control the location and coating characteristics of the polymerizable liquid mixture, a latent period provided by the catalyst system can be especially advantageous. The catalyst system is an organo metallic compound wherein the metallic portion or ion has a valence which varies with conditions. Organo metallic compounds of cobalt, nickel, iron, titanium, tin, antimony, zinc, and vanadium are examples. (17 claims)
