摘要: Systems and methods for creating a hydraulic barrier at an interface between high low permeability regions that may exist in permeability-contrast subterranean formations. These systems include providing injection and/or production wells are completed within the regions, supplying pore throat blocking agent to forming interface. The be sized substantially flow through region while being blocked, or occluded, from region. In some embodiments, greater than one acre (0.4 hectare) area. formation oil reservoir. formations swept concurrently independently remove
