Abstract:
If we produce from gas condensate reservoir while its pressure is under dew point pressure, there will be a liquid accumulation area adja cent to the well. These formed condensates cause many problems, including a negative impact on production and productivity. In fact, this destructive effect of condensate is due to the tendency of the reservoir rock to be wet with liquids, which causes the porous media to be blocked by this phase. This negative effect is so destructive that, along with other damage to the reservoir, such as skin factor, its value should be taken into account in the calculations. The research done on this issue has shown that methods can be used to open the path for the passage of gas. The best method to achieve this goal is to reduce capillary pressure, which two methods are suggested for this purpose: reducing the tendency for wetting by liquid and gas miscible injecting to reduce the interfacial tension between gas and condensate, which both of these mechanisms lead to capillary pressure reduction. Such studies need to know and evaluate the behavior of gas and condensate and the petrophysical properties of the reservoir in order to be able to chose the best chemical composition of injected gas into the reservoir. In this paper, condensate blocking problem and its solution for a gas condensate reservoir will be discussed.
