Suppose that a vertical well produces 0.71 specific gravity gas through a 2 7/8-in tubing set to the top of a gas reservoir at a depth of 10,000 ft. At tubing head, the pressure is

800 psia and the temperature is 150 F, the bottom hole temperature is 200 F. The relative roughness of tubing is about 0.0006. Calculate the expected gas production rate

of the well using the following data for IPR:

Reservoir pressure: 2,000 psia

IPR model parameter C: 0.01 Mscf/d-psi2n

IPR model parameter n: 0.8
