Abstract
An aqueous composition comprises an aminopolycarboxylic acid and a water-soluble organosilicon compound. The composition is useful for removing scale from well equipment and/or openings in a subterreanean formation, and for stabilizing fine particles within the formation to prevent their subsequent movement. Fluid flow through formations and wells treated with the composition tends to be increased and more stable.
