Table Q4 shows the PVT data for Reservoir B which operated under Constant Terminal Pressure (CTP) condition, determine the cumulative water influx in bbl unit using suitable aquifer model when the reservoir pressure drop from 1250psig to 1220psig for 15 days and further drop from 1250 psig to 1200 psig for another 20 days. Note: Refer to Appendix IV for two-phase oil volume factor. [20 marks ] Table O4 Additional Data for Reservoir B
