ASTM D2892 Data for Better C7+ Characterization in EOS Modelling

Author: Bilal Younus An EOS model requires five properties for each component in a mixture: critical pressure (pc), critical temperature (Tc), acentric factor (ω), molecular weight (M) and volume shift (s). The three first properties define the vapor pressure curve of the component, and the last two properties (parameter) ensures accurate prediction of liquid density […]

Practical Aspects of EOS Treatment in Compositional Simulators

Author: Stian Mydland When running compositional reservoir simulations, it is always good practice to quality check that the equation of state (EOS) model developed in a standalone PVT package is exported correctly to the simulator. This is achieved by taking the fluid related output from e.g. CMG GEM, Eclipse 300, or Sensor, and compare it […]
