Calculate the cumulative water influx at the end of 1 year   

Calculate the cumulative water influx at the end of 3 years  

An oil reservoir is surrounded by an aquifer. The aquiferproperties are as follows Area of oil zone=400 acres Area of aquifer and the oil zone=14400 acres Permeability=50 md Thickness=83 ft Porosity=0.25 Water viscosity=0.7cp Water compressibility-3x10-6 psi-1 Formation compressibility=5x10-6 psi-1 The pressure history between the oil zone and the aquifer is as flows in Table 3 and Fig. 1 Table 3.
