Abstract

In CO2 capture and storage (CCS) projects, measuring permeability of supercritical CO2 in porous rock is a key important factor in predicting the migration and evaluating the long-term stability of injected CO2. In this paper, a new device for measuring CO2 permeability coefficient in porous rock at reservoir conditions is described, in which the pressure and temperature of injected CO2 are usually at supercritical state. In the measurement, the supercritical CO2 flowing through rock samples is depressurized to gaseous phase whose flow rate could be easily measured with normal gas meters. An average flow rate over a period of time is used to calculate the permeability of CO2 in rock sample under supercritical state. An application example using a siltstone for testing proves that the device can measure the permeability of supercritical CO2 in porous rock effectively.
