Description

The POROPHASE system is designed to investigate the thermodynamic behavior of petroleum fluids within porous media under representative reservoir pressure and temperature conditions. The apparatus enables precise determination of the saturation point (bubble point or dew point) of a fluid confined within a porous sample. The tested fluid may consist of live oil or gas condensate, allowing the study of multiphase behavior in reservoir rock. Real-time visualization of phase transitions is achieved using a high-resolution video camera positioned at the front face of the core sample. The porous sample is installed in a high-pressure core holder and subjected to controlled confining pressure and absolute temperature representative of reservoir conditions, enabling faithful reproduction of in-situ environments. The core holder features a transparent sapphire end cap, providing complete visual access to the sample throughout the experiment, while the integrated video system continuously monitors the transition from single-phase to two-phase flow.
