Essential part of PVT analysis 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) to multi-component and multi-phase (like saturated oil) and assumed to be in chemical, 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 |
