Petroleum Reservoir that reside in reservoirs with the original temperatures lying between the pseudo-critical temperature and the Cricondentherm .
Natural Gas Reservoir with initial formation temperature lying between the pseudo-critical temperature and the Cricondentherm , which initially stays gaseuous (outside Vapour Liquid Envelope) and builds condensate at separator (inside Vapour Liquid Envelope, see Fig. 1).
