The study of depletion performance of gas condensate reservoirs has gained wide interest in petroleum industry during the last few decades and poses a challenge for the reservoir modeler. Upon depletion, reservoir pressure may fall below the dew–point of hydrocarbon mixture which results in liquid condensation at reservoir conditions. The condensation presence will hinder the flow of hydrocarbons and severely obstruct their recovery. This becomes highly noticeable for the case of tight reservoirs (less than 10 md). Hence, it is critical to answer this question whether this trapped gas has been irreversibly lost or not. It is believed that the interplay of Darcian–type flow and Fickian type flow (multimechanistic flow) is the key to answering this question. In this work, we show the dominant flow processes and recovery mechanisms taking place in gas–condensate reservoirs and describe the depletion performance of these systems, which provides guidance for the development and analysis of this class of reservoirs.<\div>

Material Balance calculations for determining oil or gas in–place are based on obtaining static reservoir pressures as a function of cumulative production. This requires the wells to be shut–in, in order to determine the average reservoir pressure.The Dynamic Material Balance is applicable to either constant flow rate or variable flow rate, and can be used for both gas and oil. The Dynamic Material Balance is a procedure that converts the flowing pressure at any point in time to the average reservoir pressure that exists in the reservoir at that time. Once that is done, the classical material balance calculations become applicable, and a conventional material balance plot can be generated.The procedure is graphical and very straightforward: a) knowing the flow rate and flowing sandface pressure at any given point in time, convert the measured flowing pressure to the average pressure that exists in the reservoir at that time; b) use this calculated average reservoir pressure and the corresponding cumulative production, to calculate the original oil or gas in place by traditional methods. The method is illustrated using data sets<\div>
