Question

A water well with a 12 inch well bore is drilled on 40 acre spacing. The permeability of the pay is 100 md and is 10 ft thick. The flowing pressure at the well bore is 200 psia and the shut in pressure is 500 psia. Calculate the rate of flow of the water into the well bore if μ=1 cp and Sw= 100%. (1 acre = 43,560 ft2).
