Paper presented at the Carbon Management Technology Conference, July 15–18, 2019
Paper Number: CMTC-552268-MS
... Abstract The matrix permeability of the tight sandstone reservoir is very low, which causes difficulty to inject water, the CO 2 flooding is applied widely to these reservoirs for the better oil displacement and low injection pressure, but natural fractures develop as well as artificial...

... 2 front is controlled by the relative permeability of two phases and capillary pressure. Water saturation profile from CO 2 injecting point to the displacement front shows that water saturation behind the CO 2 front increases outwardly, and the change in saturation is non-linear. The injection...
