ABSTRACT:
A process for controlling the migration of a gelling composition for enhanced oil recovery by blocking water or gas coning comprises injecting a gelling composition into a subterranean formation where the density of the gelling composition is adjusted depending on the density of the formation brine or oil so that the gelling composition gels in a desired location of the formation.
