Abstract Shale gas and shale oil are the typical ones of unconventional reservoirs in the past decade. Some research studies focused on the effect of porous media on the dew point of gas condensate and bubble point of crude oil systems in terms of experimental and theoretical work. They reached to the contradictory conclusions. Therefore, it is of great importance to develop an effective method to predict the phase behavior of shale gas and shale oil in porous media and investigate the effect of some factors on the saturation pressures of shale gas and shale oil in unconventional reservoirs. In this work, by taking into account the effect of capillarity on saturation pressures of gas condensate and crude oil systems, the theoretical model has been developed to predict the phase behavior of shale gas and shale oil in unconventional reservoirs. The Parachor model is applied to determine the interfacial tension of crude oil and gas condensate. Some case studies were completed to address the effect of porous media on the phase behavior of reservoir fluids. The effect tendency of some properties of porous media on the dew or bubble point of reservoir fluid is discussed in this paper. |
