Gas-water flow in carbonates

0.5 PV, 1.25 PV and 2 PV of gas was injected at the flow rate of 0.005 mL/min, corresponding to gas flooding 1, gas flooding 2 and gas flooding 3 respectively. Then, the gas flow rate was increased to 0.01 mL/min, and the sample was scanned after 2 PV gas flloding (gas flooding 4). The brine was injected at the flow rate of 0.01 mL/min, and the first water flooding image was obtained at 0.01 MPa of pore pressure. Then the pore pressure was gradually increased to 1 MPa, 2 MPa, 3MPa and 4 MPa, respectively corresponding to water flooding 2, water flooding 3, water flooding 4 and water flooding 5.
