27. The following data was available after a well control operation: Well depth 14567 ft MD 7895 ft TVD Air gap 75 ft Water depth 1250 ft Choke line length 1356 ft Drilling fluid density 11.8 ppg Kill fluid density 12.8 ppg Sea water gradient 0.445 psi/ft Atmospheric pressure 14.7 psi Kill mud has been circulated back to surface, the well shut in and pressures monitored for 15 minutes, with no build up, the well was opened up through the remote choke and observed on the trip tank for a further 15 minutes with no flow. The riser has yet to be displaced to kill mud and it is estimated that 2 bbls of gas are trapped below the upper pipe rams. Calculate the expanded volume of gas at surface using the data above.
