Question

a) Calculate the water influx after 50, 150, 350, and 650 days into a reservoir, the boundary pressure of which is suddenly lowered and held at 2764 psia from the initial pressure of 2784 psia. Given data: φ = 0.2, k = 83 md, Cw = 8 * 10^-6 psi^-1, Swi = 0.3, M = 0.62 cp, φc = 360°, h = 40 ft, L = 30,000 ft. b) In the above numerical, at the end of 120 days, if the boundary pressure is suddenly lowered to 2724 psia, what will be the water influx at the end of 550 days total time?
