Abstract
A gelation system for reducing the permeability of a subterranean region is provided by sequentially injecting slugs of a polymer solution and a crosslinking agent solution capable of crosslinking the polymer. The viscosity of the crosslinking agent solution is adjusted to facilitate mixing of the slugs in the desired treatment region to a form gel therein and minimize premature gelation outside of the treatment region.
