CO2 Flood: Field Operation: Reservoir P & T

1.Since reservoir’s temperature, in general, exceeds the critical temperature of CO2 (31 deg C), whether, CO2’s density will keep on increasing with pressure (with CO2 behaving as a vapor)?

2.Why does a successful CO2 flooding require a minimum reservoir pressure of 1500 psi?

3.How does diagenesis critically control the dynamics of CO2 flood?

4.Why does infill drilling remain to be so crucial towards achieving sweep efficiency of CO2, despite having control over various exploitation processes towards determining well spacing?
