PNGE 4612 Well Testing Homework #2 Due date 21/03/2022 An oil reservoir has three wells (X, Y, and Z), well X is at a distance of 40 ft from well Y and 50 ft from well Z. Well X is producing at 900 b/d, well Y at 70 b/d and well Z at 250 b/d. Calculate and plot the wellbore flowing pressure at well X (P vs. t) for the following times: 1, 7, 15, 80 and 120 hrs due to production at X, X&Y, X&Z, and X, Y, & Z knowing that skin at X is 2. Calculate and plot the wellbore flowing pressure (P vs. t) at well X due to production at X only for S= -2,0, and 2. The following reservoir properties are given: Initial reservoir pressure - 3000 psia Drainage radius = 3500 ft k 80 md B. - 1.2 rb/stb C1-10-05 psi" Well radius=0.5 ft h = 50 ft Ho - 0.5 cp -0.2 PNGE 4612 Well Testing Homework #2 Due date 21/03/2022 An oil reservoir has three wells (X, Y, and Z), well X is at a distance of 40 ft from well Y and 50 ft from well Z.
