Natural Gas Reservoir with initial formation temperature $\begin{array}{l}T_i > T_{c, \rm max}\end{array}$ above Cricondentherm $\begin{array}{l}T_{c, \rm max}\end{array}$ and stays gaseuous at separator (outside Vapour Liquid Envelope, see Fig. 1).

Fig. 1. Production path of the Dry Gas Reservoir on the Phase Equilibrium Diagram.

The downward solid black arrow shows a reservoir pressure depletion path.

The downward grey dash arrow shows a wellbore lift pressure drop path.
