Abstract

A method for fluid control or plugging of a well by injecting a mixture of an acid polymerizable resin, a polar organic diluent, and an acid catalyst, and later injecting an acidic fluid to quick-set a portion of the resin and hold it in place while the pre-mixed catalyst sets the resin. In an alternate sand consolidation embodiment, a fluid slug is injected between the resin and acidic fluid injections to create permeability in the resin saturated area of the formation prior to final set of the resin.
