Methods to analyze buildup responses in gas-condensate reservoirs producing below the dewpoint pressure are examined. Two analogs to compute formation flow capacity and average reservoir pressure are presented. These analogs are based on the steady-state theory (developed by O'Dell and Miller and later modified by Fussell) and the single-phase-flow theory (which ignores the existence of the two phases). The mechanical skin factor can be computed from the derivative response by computing the appropriate dimensionless pseudopressure.
