ABSTRACT:
Crosslinkable-polymer compositions are provided that may be useful for, among other things, reducing, stopping, or diverting the flow of fluids in subterranean formations. The crosslinkable-polymer compositions may comprise an aqueous fluid, a chitosan-reacting polymer, chitosan, and a gelation-retarding additive comprising an acid derivative. Various methods of use are also provided.
