ABSTRACT:
In an inverted nine-spot pattern in an areally homogeneous reservoir, oil recovery is enhanced when the completion of the sidewells is restricted to the lower 20% of the reservoir. An inverted nine-spot pattern has a steam injection well at the center of the pattern and production wells at each of the four corners of the pattern and at the center of each side of the pattern. Steam is injected at the center well, and oil is produced from sidewells and corner wells.
