ECLIPSE Compositional Simulation

4.5 Average client rating (based on 163 attendee reviews)

When oil consists of two or more hydrocarbons and those hydrocarbons exhibit distinctly different phase and composition changes relative to temperature and pressure, more complex definitions of fluid behavior are required for reservoir simulation and predictions of recovery. Compositional simulation is useful when an equation of state is required to describe reservoir fluid phase behavior or the compositional changes associated with depth. A compositional model is the right choice for studying condensates or volatile crude oils, gas injection programs, and secondary recovery studies. Knowledge of compositional behavior is also required for accurate planning and design of surface production facilities.
