A gel-forming composition is provided comprising a PVA based substance selected from the group consisting of a polyvinyl alcohol, a polyvinyl alcohol copolymer, and mixtures thereof, an aldehyde operable for crosslinking with the PVA based substance, and water. The gel-forming composition is useful for reducing steam channeling in subterranean formations. For example, a method is provided for diverting the flow of injected steam in nonproductive steam channels in an oil reservoir during waterflood and steam cycling operations.
