Abstract:
A method of consolidating particulate solids in a subterranean zone penetrated by a wellbore when there is a lack of closure pressure exerted on the particulate solids in the zone or when the particulate solids are seperated by films of unbroken viscous carrier fluid in the zone, or both, comprising the steps of:(a) preparing a hardenable resin composition comprised of a hardenable organic resin, an aminosilane resin-to-particulate solid coupling agent, a viscous carrier fluid breaker for breaking said carrier fluid films and a surface active agent for causing said resin composition to flow to contact points between said particulate solids;(b) injecting said composition prepared in step (a) into said subterranean zone and coating said particulate solids present therein with said hardenable resin composition prepared in step (a); and(c) allowing said resin composition to harden and consolidate said particulate solids in said zone into a permeable pack of high compressive strength.
