Abstract of the Disclosure A gelable composition is provided which can be injected into a well prior to steam treatment of the well. The composition comprises water, a water-dispersible polymer, a water-dispersible first crosslinker and a water-dispersible second crosslinker, wherein the first and second crosslinkers have differing temperature responsive crosslinking characteristics over the temperature range of about 70°F to about 400°F so as to enable crosslinking of the polymer and gelation of the composition over substantially the entire temperature range. Injection of the composition into a "cold" well followed by steam treatment of the well causes the polymer to undergo a two stage crosslinking reaction which produces a particularly effective and stable gel in diverting steam from "thief zones" in the formation surrounding the well.
