A 0.7 specific gravity gas well is flowing under a bottom-hole flowing pressure of 1900 psi. The current reservoir pressure is 2100 psi and the reservoir temperature is 140 °F. The following additional data are available: h=40 ft, rw 0.33 ft, re=1000 ft, k = 60 md Calculate the gas flow rate by using • Real-gas pseudopressure approach. • Pressure-squared method. Compare your results and explain the cause of the difference if there is any (Hint. Z factor can be calculated using a correlation such as Sutton correlation presented in the book Applied Petroleum Reservoir Engineering or Petroleum Fluid Properties books for example)
