Assessment of CO2 geological storage capacity in the oilfields of the Songliao Basin, northeastern China

Enhanced oil recovery through carbon dioxide injection (CO2-EOR) data has made it possible to estimate the CO2 geological storage in the oilfields of the Songliao Basin, northeastern China. The storage capacity of CO2 in oilfields was determined and the results show that the theoretical storage capacity of CO2 in the oilfields of the Songliao Basin is 2.36 × 109 t, and the effective storage capacity is 0.59 × 109 t with an effective coefficient...
