Alternate dual-engergy gamma-ray attenuation technique: A new tool for three-fluid saturation measurements in lOR flood experiments

Many oil recovery processes, such as gas injection or gas-cap expansion in an already water-flooded zone, or water-alternate-gas flooding, involve three-phase flow. A new dual-energy gamma-ray attenuation technique is described, which allows for gas, oil, water saturation profile measurements during the physical simulation of improved oil recovery processes at reservoir conditions.
