Abstract:
A method of treating a subterranean formation penetrated by a wellbore includes introducing a treatment fluid comprised at least a crosslinkable component, and a metal crosslinker to the subterranean formation, forming a crosslinked treatment fluid, and de-crosslinking bonds of the crosslinked treatment fluid by manipulating a pH of the treatment fluid with a pH triggering agent, wherein the pH triggering agent is an amine-precursor compound or a derivative thereof.
