Construction of 3D geomechanical model has special importance in predicting reservoir performance and can be used as a useful tool in reservoir management. For example, construction of geomechanical model helps in the design of drilling operations, wellbore stability, fault stability, rock mechanical behavior and etc. In this study, the 3D geomechanical characteristics of the field located in the northeast of the Persian Gulf have been investigated in order to evaluate the mechanical properties of the reservoir rock. Young's modulus has been estimated in the mentioned reservoir. The variogram data and geostatistical methods have been used to construct a 3D model. In the mentioned model, Median averaging method and 3D petrophysical modeling interpolation methods such as SGS, Kriging, Co-Kriging, and Moving average have been investigated in five wells. In order to estimate the best result in 3D geomechanical modeling, the designed model has been compared with the data of a well. The results of this study show that the CoKriging method with R2=0.987309 is the most suitable method for 3D geomechanical modeling of this field.
