Consideration of retrograde loss in determining the optimum economic operation of a gas condensate reservoir
It is not possible to distinguish a wet-gas reservoir from a retrograde condensate reservoir from surface producing characteristics, such as gas-oil ratio, tank liquid gravity, etc. From a practical standpoint, however, it may be considered that any reservoir which produces condensate in excess of 10 bbl per million cu ft of separator gas will behave as a retrograde condensate reservoir. On the other extreme, retrograde condensate reservoirs may produce as much as 350 bbl or more of stock tank condensate per million cu ft of separator gas. In all but the very rich condensate reservoir, the liquid condensed in the reservoir cannot be produced under normal depletion conditions. A description is given of a laboratory study and associated calculations to determine the effect of retrograde condensation upon the yield from a gas-condensate reservoir under pressure depletion conditions. The laboratory study may be tailored to fit the separation conditions in use in the field or to conditions anticipated for the future. A variety of conditions may be considered for comparative purposes. Figures are presented to calculate gasoline plant recovery either in conjunction with lease separation or for the case where the entire well stream is processed.
