Influence of water saturation and water memory on CO2 hydrate formation/dissociation in porous media under flowing condition

Evaluation of CO2 Hydrate Saturation in Porous Core Experiments Using Medical CT Images

“…The apparatus (see Figure 1), material, and experimental procedure were described in detail in our previous study. 15 In brief, the system was pressurized to 3 MPa under N 2 flow using a back pressure regulator at the core outlet (BP in Figure 1). Subsequently, N 2 and degassed brine solution containing 1 wt % NaCl were simultaneously coinjected into the core using a specific gas/water fractional flow (f g /f w ) 16 to establish the desired brine saturation (S w ∼ 35%).…”
