Abstract
The probable extent of the two phase region in the Baca reservoir is very sensitive to the CO2 content of the fluid. As the reservoir fluid is produced, CO2 is preferentially transferred to the gaseous phase. Pressure/temperature measurements in flowing wells are not useful for determination of the CO2 content. Values for the CO2 content determined by direct chemical analysis of the discharge fluid may in general be either higher or lower than that in the reservoir. Values from discharge fluids at Baca should be regarded as a lower bound on the CO2 mass fraction characterizing the system as a whole.
