Calculate the flowing bottomhole pressure profile along the tubing length using the Cullender-Smith method. Plot the results. Suppose 2MMscf/d of 0.65 specific gravity gas is produced through a 27/8-in. (2.259-in. inside diameter) tubing string set to the top of a gas reservoir at a depth of 5,000 ft. Tubing head pressure is 300 psia and the temperature is 100F; the bottom-hole temperature is 150F. The relative roughness of tubing is about 0.0006
