Abstract:
The present invention relates to methods for recovering hydrocarbons from subterranean formations. One such example embodiment injects a polymer solution into an upper layer of a subterranean formation and, likewise, injects an aqueous solution into a lower layer of the subterranean formation. Hydrocarbons displaced by at least one of the injected polymer and the injected aqueous solution are collected.
