In case of the compressible gas flow the mathematical model of the PI is studied for the first time. In contrast to slightly compressible fluid the PI stays ``almost'' constant for a long period of time, but then it blows up as time approaches the certain critical value.

The capillary pressures are assumed to be negligible [21, 13]. Accordingly, all the present phases in the reservoir have the same pressure.

An oil and gas reservoir is a formation of rock in which oil and natural gas has accumulated within. The oil and gas collect in the small, connected pore spaces of rock and are sealed below ground surface by an impermeable layer of rock. [1]

At very high pressures, the gas becomes less compressible (Z increases with P), as the gas molecules begin to occupy an increasingly significant fraction of the total gas volume. Strictly speaking, the ideal gas equation functions well when intermolecular attractions between gas molecules are negligible and the gas molecules themselves do not ...

Conventional Wells In a conventional gas well, the reservoir pressure must overcome the wellbore pressure for gas to be produced. As the well matures and the reservoir pressure depletes, it becomes more difficult for the gas to naturally flow into the wellbore.
