Evaluation of the mechanical properties of reservoir rocks is an essential criterion in determining suitable points for hydraulic fracturing operations. Meanwhile, Young's modulus and Poisson's ratio are two mechanical parameters controlling rock layers' brittleness. These two parameters can be calculated by performing tests on rock samples in different laboratory conditions (static method) or using sonic and density log data (dynamic method). The calculation of dynamic elastic moduli requires shear wave velocity data, which, despite its great importance, is only measured in a small number of wells in the field due to the limitation and high cost of measurement. In this study, due to the lack of shear wave velocity in the well in question, the bulk and shear moduli of the rock were estimated with the help of a carbonate rock physics model. Then, by calculating Poisson's ratio and Young's dynamic modulus and using the laboratory relationship to convert these moduli into the static state, the brittleness index was determined, and considering the effective reservoir parameters, the candidate layers for hydraulic fracturing operations were identified and prioritized.
