Abstract:
Nowadays, we know that many hydrocarbon reservoirs are fractured regarding this, the investigation of the properties of these reservoirs is necessary to predict the storage, production and the drilling methods. To identify fractured reservoirs, the fracture properties and their geometries under different conditions should be investigated. Besides, the evaluation of the behavior of induced fractures in distinct under ground conditions is very important. The Mechanical properties of the drilling bed like crack propagation, layer and mass rock is impactful in planning of drilling process and hydraulic fracturing operation. In this research, at first we introduce natural and induced fractures then we analyze the rock behavior under principal stresses and finally we assess the rock toughness in SCB method for cracks with different angle. We also employ GMTS index to predict the fracture toughness and the angle of crack propagation and to evaluate the result accuracy in comparison with experimental data
