AUTOFLOOD 700 HC-Unsteady state CO2-brine relative permeameter


The AUTOFLOOD 700 HC system employs the unsteady-state method to precisely ascertain both absolute permeability and relative permeabilities for liquid/liquid and liquid/gas systems under reservoir-level pressure and temperature conditions. It is particularly well-suited for determining CO2-brine relative permeability in unsteady-state mode, offering the flexibility to inject CO2 in gas, liquid, or supercritical phases to replicate reservoir conditions accurately. In Carbon storage programs, this AUTOFLOOD 700 HC holds significant value for determining CO2-brine relative permeability properties. This data addresses multiple trapping mechanisms related to capillary trapping, residual trapping, immiscible displacement, hysteresis effects, mobility control, storage efficiency, and the prediction of potential CO2 leakage. This data is crucial for designing and operating CCUS projects in saline aquifers with a focus on efficient, safe, and long-term carbon storage.
