A 20 bbl gas influx has entered a well at bottom hole pressure of 3,500 psi. Determine the gas volume when the kick exits the well.
a) Assume atmospheric pressure of 14.4 psia and no change in gas temperature
b) Assume initial gas temperature of 150 degrees F and surface temperature of 65 degrees F
c) What is the density of the gas from the previous example if it contains 90% methane 10 % ethane under bottom hole condition (assume T=150 degrees F)
