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)1.85. 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, p=0.0185 cp, C = 3.5 × 10-5 psi-¹ (8 marks)
