Abstract:
An all-oil reversible gelling system includes a polymer, a crosslinker, a gel accelerator, and an oxidant, wherein temperature activates the crosslinker so as to cause the system to form a gel, and the oxidant subsequently decomposes the gel. This gel is designed to seal temporarily portions of oil-producing or water or gas injecting subterranean formations.
