NER’s upstream CO2/brine pore pressure module serves as either an add-on to an NER AutoLab system or as a stand-alone fluid mixing and delivery system for general use with other equipment. The module is configured as a stand-alone mobile cart that can be easily moved to various testing apparatuses and docked for use during active flooding of CO2 saturated brines or supercritical CO2. Typical pressure and temperature limitations are 70 MPa and 120°C.
