Abstract
A process for enhanced recovery of petroleum from subterranean formations is disclosed, wherein steam is injected into a formation via an injection well, and a mixture of petroleum and steam condensate is produced via a production well, wherein the produced mixture is flashed for production of a steam-distilled hydrocarbon fraction, and wherein the steam distilled hydrocarbon fraction is injected, with additional steam, into a subterranean formation for increased recovery of petroleum. The process disclosed is particularly useful in recovery of heavy (low API gravity) petroleum.
