Reservoir depletion calculations for gas condensates using extended analyses in the peng‐robinson equation of state

Abstract

AbstractThe Peng‐Robinson‐AGA computer program was applied to the predicting of liquid yields in flash and stepwise depletion calculations. Prior tests of the validity of the program were based on agreement between bubble and dew point pressures and equilibrium constants. Here, the liquid yields under ietrograde conditions were compared with only a moderate degree of agreement. The need for accurate extended analyses of condensate systems as well as the documentation of an accurate characterization of the cuts is emphasized.
