Gas injection affects Marun field PVT properties

Mohammad Jamshidnezhad, National Iranian South Oil Co. Ahwaz, IranA study determined the changes in pressure-volume-temperature (PVT) properties caused by gas injection in the Marun field Asmari carbonate reservoir in Iran.The study calibrated the equation-of-state models for compositional simulation and established a means for predicting fluid properties in all areas of the field.The study was part of a broader effort to characterize reservoir fluids for compositional simulation. Laboratory PVT reports on 19 appraisal wells (15 wells before gas injection and 4 wells after gas injection) were the basis for the compositional simulation.The study applied a Peng-Robinson equation of state (E...
