ABSTRACT:
Disclosed is an invention for optimizing recovery of petroleum from a subterranean, petroleum containing formation by improving the efficiency of a steam drive through a linear heat reduction schedule and a partial shut-in of the producing well after steam breakthrough. The linear heat reduction schedule and the partial shut-in to compensate for steam override results in maximized discounted net oil recovery with optimal utilization of steam generation capacity.
