An oil reservoir is located between two intersecting faults as shown below. The oil reservoir is bounded by an aquifer estimated by geologists to have an external radius of 75000ft. Use Hurst and van Everdingen method to calculate the water influx that occurred after 200 days (assume edge type water drive). Other aquifer data are as follows: k=100mD,w=1cp,h=100ft,=21.1%,ct=1106psi1,ro=10000ft. The aquifer-oil boundary pressure history is as follows. fault
