In addition to many of the features available in the Eclipse core simulator, the Eclipse compositional simulator includes functionality dedicated to modeling multicomponent fluid reservoirs:

  • Cubic equation of state (EOS), with the ability to define EOS regions.
  • Gas injection, to increase or maintain reservoir pressure.
  • Miscible flooding as the injection gas goes into solution with oil.
  • Carbon dioxide flooding, with the gas soluble in both oil and water.
  • Modeling of thick reservoirs with a compositional gradient due to gravity.
  • Modeling of reservoirs with fluid compositions near the bubble point.
  • Assessment of asphaltene precipitation impacts on reservoir performance.
  • Chemical reactions, combustion, biodegradation, decay of radioactive tracers, and non-equilibrium reactions.
