Q5/ A gas well is centered in a radial cylindrical reservoir with fixed pressure at the outer reservoir boundary. The production rate is 200 Mscfd and remains constant. The effect of reservoir boundary is felt when to = (rp)185. Calculate the cumulative gas production just 4 days before the effect of outer boundary is felt. Additional data: re = 2000 ft, rw=0.4 ft, k = 9 md, Ø 0.11, -0.0185 cp, C=3.5 × 105 psi-¹
