Abstract:
The Integrated Reservoir Modeling of Shaldanadi Gas Field using Petrel software is a study aimed at 
improving the understanding of the reservoir characteristics and behavior of the Shaldanadi Gas Field. The 
modeling was carried out using Petrel, a powerful and widely used software in the oil and gas industry. The 
study utilized various techniques such as geophysical analysis, stratigraphic modeling, structural modeling, 
poperty modeling, well engineering of the reservoir. The working strategy includes geological works, 
engineering knowledge (well engineering, petrophysical analysis), fluid properties etc. By this integrated 
reservoir simulation static model, velocity model, porosity modeling, permeability modeling etc. The 
reservoir is devided into numbers of grid cell and each cell shows the gradual changing in porosity, 
permeability and other petrophysical properties. The gas-water contacts of each zone are also shown. After 
all, the findings of the study provide important insights into the reservoir behavior and could be used to 
support future decision making and operational activities in the Shaldanadi Gas Field.
