Abstract:
In the second talk of the CCS Knowledge Transfer Series, we will discuss the physics and thermodynamics of CO2 flow in relation to CCS. We will highlight key differences, in terms of phase behaviour, between CO2 and other fluids more typically encountered in oil and gas operations, and the implications these have on multiphase flow in the reservoir. The main flow mechanisms, as well as physical scaling laws incorporating capillarity, buoyancy and viscosity will be discussed and used to analyse the flow regimes typically encountered in the field. The talk will end with discussion on dissolution, residual, and mineral trapping mechanisms.
