    Description

    Magnetic-resonance imaging (MRI) provides a wealth of information on petroleum-flooding-displacement mechanisms and in-situ pore-level behavior. This study demonstrates MRI methods that have potential for studying the mechanisms of carbon dioxide (CO2) displacement processes in Berea core plugs during the recovery of decane and heavy oil. The correlation between fluid saturation and transverse relaxation time (T2) revealed the contrast in decane/pore-surface interaction between miscible and immiscible drainage of decane by CO2. T2 profiles demonstrated changes in the composition and viscosity of the heavy oil caused by the extraction of light components by CO2.
