Abstract
A method for consolidating a subterranean formation to control the production of particulates therefrom. A specific consolidating solution comprised of an allyl monomer and an initiator is injected into the formation where it is allowed to set at an elevated temperature to harden and form a permeable, consolidated mass. The allyl monomer is an allyl ester selected from the group of diallyl orthophthalate, diallyl isophthalate, diallyl terephthalate, diallyl benzenephosphonate, diethylene glycol bis (allyl carbonate) and other known allyl monomers and the initiator is preferably a peroxy compound (e.g. benzoyl peroxide, diisopropyl peroxydicarbonate, etc.) or an azo compound (e.g. 4,4'-azobis(4-cyanovaleric acid). A diluent such as an alcohol (e.g. isopropyl alcohol or isobutyl alcohol) or a mutual solvent (e.g. ethylene glycol monobutyl ether, diacetin, triacetin, acetone, etc.) and a coupling agent (e.g. an organofunctional silane) may be added if needed.
