Essential part of PVT analysis responsible for predicting the dynamic fluid properties at various temperature and pressure based on the laboratory tests of available fluid samples.
The fluids are assumed to be multi-component and multi-phase and stay in thermal and hydrodynamic equilibrium.
Below is the list of the most popular PVT models:
| Abbreviation | Description | Components |
|---|---|---|
| GAS | Dry Gas | Gas |
| DO | Dead Oil (degaisfied oil) | Oil |
| BO | Black Oil | Water, oil wth saturated gas, gas |
| MBO | Modified Black Oil ( also called Volatile Oil ) | Water, oil with saturated gas, gas with oil vapour |
| EOS | Equation of State ( also called Compositional ) | Water, alkanes components, minor inclusions |
| Water | Water | Water |
