  • Controlling steam distribution
    Patent number: 4641709
    Abstract: An enhanced oil recovery technique includes the predetermination of a desired steam distribution within a steam flood pattern, which preferably is proportional to the volumes of oil in place within various sectors of an area of a subsurface formation. These sectors are associated with the various producing wells of the steam flood pattern. Initial steam distribution is then determined. Subsequently, one or more of the producing wells has its production rate modified so that the final steam distribution within the formation will more closely approximate the predetermined preferred steam distribution.
