ECLIPSE Compositional Simulation
The ECLIPSE Compositional simulator 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.
Compositional simulation is ideally suited for
- gas injection (due to gas stripping)
- miscible flooding (as the injection gas goes into solution with oil)
- carbon dioxide flooding, with the gas soluble in both oil and water
- thick reservoirs with a compositional gradient due to gravity
- reservoirs with fluid compositions near the bubblepoint
- high-pressure, high-temperature reservoirs
- natural-fracture reservoir modeling.
