Abstract
Fibers are added to a gelation solution and the mixture is pumped to a subterranean injection site where it gels in place. The gelation solution is preferably comprised of partially hydrolyzed polyacrylamide polymer and a crosslinking agent, while the fibers are those which do not interfere with the gelation process and can provide adequate reinforcement while not adversely affecting the ability of the solution to be pumped and injected. Glass fibers and cellulosic fibers are specifically disclosed as preferable reinforcing fibers.
