A Compositional Wellbore/Reservoir Simulator to Model Multiphase Flow and Temperature Distribution

Production of hydrocarbon often involves gas and liquid (oil/water) concurrent flow in the wellbore. As a multi-phase/multicomponent<br>gas-oil mixture flows from the reservoir to the surface, pressure, temperature, composition and liquid holdup<br>distributions are interrelated. However, nearly all two-phase wellbore simulations are currently performed using “black oil”<br>simulators.
