Composition and method for fluid loss control in acid fracturing of earthen formations
Novel compositions and method of controlling fluid loss during acid fracturing employing a gelled acid which is crosslinked by Fe(III) upon spending of the acid. The crosslinking is later reversed by means of a reducing agent which is activated as the pH of the spent acid rises.
