The most accurate way to simulate gas expansion is conventional 3D full-field dynamic modelling where gas motion is treated as one of the fluid phases and accounts of geological gas fluid properties, relperm properties, heat exchange .
The analytical models usually assume:
| Isothermal expansion | |
|---|---|
T = \rm const |
which leads to the following equation:
| p V = Z \frac{m}{M} T |
