Fluid inclusions provide valuable evidence of the formation temperature of minerals, the pressure on their formation environment, the fluids densities that make up the minerals, and the chemical composition of the mineralizing fluids. This data can be used to interpret temperature history, maturity, determination of diagenetic environment, cementation timing, and hydrocarbon migration related to burial history. In this study, in order to determine the physicochemical properties and the API of Asmari reservoir of Ahvaz oil field we have used core samples of 7 wells from this reservoir. These samples were subjected to microscopic, microthermometery, API determination, and Raman spectroscopy studies. The results of this study showed that based on petrographic studies, the variety of inclusions (primary, secondary, and pseudo-secondary), as well as different compounds obtained determined by Raman spectroscopy indicates the activity of different phases of charge of the Asmari reservoir. Based on microscopic studies as wel as, we also calculated the physicochemical properties (last ice melting temperature, homogenization temperature, and salinity) of the reservoir, . Based on this data, two temperature ranges show that it can be concluded that this reservoir had two different charging periods during two charging stages. Also, based on the combination of phases in the inclusions (two-phase, three-phase with oil, etc.) the charging path of the tank can be predicted.
