Question
A natural gas well contains methane, which is practically an ideal gas. The pressure at the
surface is 1000 psi.
a) What is the pressure at a depth of 20,000 ft if temperature is assumed constant at 70°F?
b) How much error would be made by assuming that methane was a constant-density fluid
at 70°F?
c) If temperature decreases at an approximate constant value of 0.070°R per ft of elevation,
what is the temperature and pressure at a depth of 20,000 ft?
