چکیده

Reservoir heterogeneities and liquid phase forming the well bore in fracture gas condensate reservoirs make the well test interpretation in these fields more complex, which require specific approaches. In this work we studied a condensate reservoir in South of Iran. Well and reservoir parameters, permeability, skin factor and initial reservoir pressure which are the basic components of well and reservoir interpretation have been calculated based on field measured data, pressure, production rate, temperature, GOR, API gathered from static reservoir testing and three phaseseparator surface testing. There are no significant difference in calculated parameters by different reservoir models in this analysis, which are evidence of satisfactory well completion operation and no needs for further modification in developing wells. The studied well has been completed in three layers of a well. Data analysis and well test interpretation in these cases(assuming gas and gas condensate cases) show that stimulation will enhanced productivity in all layers except first layer of well .The Pan system has been used in this study.
