titleOfInvention | High vertical conformance steam drive oil recovery method |
abstract | HIGH VERTICAL CONFORMANCE STEAM DRIVE OIL RECOVERY METHOD (D#77,093-F) ABSTRACT OF THE DISCLOSURE The vertical or both vertical and horizontal conformance of a steam drive process is improved by employ-ing one or more infill wells between the injection well and production well, the infill well being in fluid com-munication with the bottom half or less of the formation. In the first step, petroleum is recovered from the infill well after oil production at the production well has pro-ceeded to a predetermined point. After water cut of fluids being produced from the infill well reaches a predetermined value, the production well is converted from a production well to an injection well and steam is injected into the converted well while continuing recovering fluids from the infill well. When one infill well is employed in a more or less aligned arrangment between injection and production wells, the vertical conformance is improved. When one or more infill wells are utilized in a pattern comprising one or more injectors and one or more producers, both horizontal and vertical conformance is improved. I |
