... and validated by a two-phase envelope generated by an Equation of State (EOS). FATS results are validated by the EOS based reservoir simulator GEM. A compositional simulation model is coupled with reservoir geomechanics in this study to investigate the interaction of stress changes and its effects...

... Abstract Reliable predictions in compositional reservoir simulators require a proper equation of state to describe accurately the phase behavior of fluids both in sub/super-critical regions. In miscible processes such as CO2 and lean gas injections, the injected fluid is usually at it's super...

... ]. In simple terms, the z -factor is a correction factor that allows us to use the ideal gas equation-of-state to model the behavior of real gas mixtures at pressures and temperatures much greater than ideal conditions. The most accurate way to quantify natural gas z -factors — especially for gas...

... of incomplete surface and/or downhole separation. Given this reality, the PVT analysis of any fluid sample with an equation-of-state (EOS) model demands that the results are verified with independent measurements. Our analyses of many samples show that a good correspondence exists between the PVT-derived...
