Abstract
A dual core flooding apparatus and process are disclosed that provide for testing of two core plugs using different orientations and multiple fluids. The dual core flooding apparatus includes at least two core holders each configured to contain a core plug. The dual core flooding apparatus includes a fluids delivery system configured to inject one or more fluids into the core holders and core plugs. The dual core flooding apparatus includes an image capture system, a density and viscosity measurement system, and at least two oil/water separators. The dual core flooding apparatus also includes at least two back pressure regulators and an automated confining pressure system. A dual core flooding process may include introducing at least one fluid into the core holders, maintaining confining pressure and back pressure, and measuring density and viscosity of existing fluids.
