Abstract
Disclosed is an improvement in a method for treating wells penetrating subsurface formations and in fluid communication with at least a portion of the subsurface formation for the purpose of sand consolidation, water exclusion, or well plugging, employing a treating fluid comprising acid catalyzed polymerizable resin, a hydrolyzable ester and an acid catalyst, which improvement provides greater control of set time and greater safety, which comprises replacing from a small percent up to the entire amount of hydrolyzable ester with an acetate derivative of the polymerizable resin, and optionally replacing a small percent up to the entire amount of the polymerizable resin with the acetate derivative. In the preferred embodiment furfuryl acetate replaces part to all of the hydrolyzable ester and, optionally, a percentage of the furfuryl alcohol.
