An oil well is developed on the center of a 40 acre square-drilling pattern. The well is producing at a constant flow rate of 100 STB/day under a semisteady-state condition. The reservoir has the following properties: = 15%, h = 30 ft, k = 20 md N = 1.5 cp, B. = 1.2 bbl/STB, C = 25 x 10-6 psi! Di = 4500 psi, rw = 0.25 ft, A= 40 acres = = Calculate and plot the bottom-hole flowing pressure as a function of time murau Behind
