The ultimate part of PVT study responsible for predicting dynamic fluid properties at various temperature and pressure based on the laboratory tests of available fluid samples.
The fluids may vary from simple (like water or methane) to multi-component and multi-phase (like live oil) and assumed to be in thermodynamic equilibrium.
Below is the list of the most popular categories of fluid models:
| Abbreviation | Description | Components |
|---|---|---|
| GAS | Dry Gas | Natural gas |
| DO | Dead Oil (degaisfied oil) | Dead oil |
| BO | Black Oil | Water, dead oil wth solution gas, natural gas |
| MBO / VO | Modified Black Oil ( also called Volatile Oil ) | Water, dead oil with solution gas, natural gas with volatile oil |
| EOS | Equation of State ( also called Compositional ) | Water, alkanes components, minor organic and inorganic chemical substances |
| Water | Water | Water |
