Reservoir fluids can be classified into five different categories: black oil, volatile oil, gas condensates, wet gas, and dry gas. The classification of the fluid can be determined by laboratory analysis and from field data. This is summarized in Table 1 below. Gas condensate reservoirs usually experience the condensate banking effect. Condensate occurs when either the reservoir pressure of a gas reservoir or the bottom-hole pressure falls below the dew point. Condensate is usually known for impeding productivity, however, different mobility zones occur due to the existence of two phases and the various forces acting upon the rock and fluid. The best approach to understand the performance of a gas condensate well is by analyzing the transient data during pressure build up, which can help to understand the condensate region in terms of its size, mobility reduction, and how it affects the well productivity.
