Methods of treating subterranean formations using derivatized gelling agents

Abstract

One embodiment of the present invention provides methods of treating a subterranean formation with a viscosified treatment fluid comprising combining water, a carbonyl-containing first compound, and an amine-containing second compound; wherein the carbonyl-containing first compound comprises at least one carbonyl moiety and is either a gelling agent or a derivatizing agent, and wherein the amine-containing second compound comprises at least one amine moiety and is a gelling agent when the carbonyl-containing first compound is a derivatizing agent and is a derivatizing agent when the carbonyl-containing first compound is a gelling agent; allowing at least one carbonyl moiety from the first compound and at least one amine moiety from the second compound to form a derivatizing linkage and create a derivatized gelling agent; and, placing the viscosified treatment fluid into a portion of a subterranean formation
