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.
