GEL AND PROCESS FOR RETARDING FLUID FLOW ABSTRACT A gel-forming composition is provided comprising a first substance selected from the group consisting of a polyvinyl alcohol, a polyvinyl alcohol copolymer, and mixtures thereof, glutaraldehyde, and water, and which does not require a separately provided acidic catalyst to crosslink and form a gel. The gel-forming composition is useful for retarding the flow of fluids in subterranean formations. For example, a method is provided for retarding the flow of water in high permeability channels in an oil reservoir. Such method is particularly useful in waterflood operations to increase the sweep efficiency of the oil recovery process. Since these gels have very good stability at elevated temperature they can be used in reservoirs having an average in situ temperature of 80°C or higher.
