Hydrocarbon and Non-hydrocarbon Gas Injection in theSouth Pars Gas Condensate Reservoir Simulation Softwareby CMG

One way to increase the efficiency of gas condensate reservoirs is injecting gas to those reservoirs. Pressure gas injection causes to maintain reservoir pressure at the top of dew point and condensation, preventing the fluid in the reservoir. In this study, the effect of injection of methane, ethane, nitrogen and carbon dioxide in the iran's south pars gas condensate reservoir has been done. In addition, thesecombination gases have also been investigated. The study of reservoir simulation software was used to simulate CMG (computer modeling group). Reservoir fluid section has been prepared using the software winprop. In between nitrogen and carbon dioxide, nitrogen has created higher efficiency in condensate production. Injecting combinatorial gases have a better effect than the two. It should be noted that thecombination of four gas injection, gas reservoir also mixed the two and requires specific post-production processes for separating is. As a result, we can say that the most effective methane gas for injection into the reservoir and reproduce it in the end beneficiaries of the condensate there.
