Numerical Well Test Analysis of Condensate Dropout Effects in Dual-Permeability Model of Naturally Fractured Gas Condensate Reservoirs: Case Studies in the South of Iran

Naturally fractured reservoirs (NFR) represent an important percentage of worldwide hydrocarbon reserves and production. The performance naturally gas condensate would be more complicated regarding both rock fluid effects. In contrast to the dual-porosity model, dual-porosity/dual-permeability (dual-permeability) model is considered as a modified in which flow wellbore occurs through matrix fracture systems. Fluid usually demonstrates intricate behavior when flowing bottom-hole pressure falls below dew point. Accordingly, different regions with characteristics are formed within reservoir. These can recognized by transient analysis. Consequently, distinguishing between reservoir effects challenging these specific needs numerical simulation. main objective this paper examine effect banking on lean rich NFRs simulation approach. Subsequently, evaluation early-time data provided single well compositional model. Then, drawdown, buildup, multirate tests conducted establish condition drops point causing retrograde condensation. results confirmed test analysis Iranian fields. Interpretations revealed that richer prone When point, derivative curves system encounter shift right, trough becomes pronounced compared one.
