Review of Mechanical Rock Properties Measurement and Estimation Techniques

Abstract

At the wellbore, the majority of mechanical rock characteristics are not immediately measured. Therefore, it is crucial to establish these characteristics employing measurable data from well logs and core samples. With this decision, numerous drilling and production difficulties over the well's life might possibly be reduced. These properties are classified into the strength parameters (rock cohesiveness, friction angle, and unconfined compressive strength of the rock) and the elastic parameters (bulk and shear moduli, Poisson's ratio, and Young's modulus). This article includes a complete review of the mechanical rock properties and their impacts on the rocks. Also, the measurement techniques (static and dynamic) of these properties were explained, and the worldwide empirical correlations for different lithologies were inserted in order to determine the static profiles of the mechanical rock properties. Lastly, this study can be used as a reference or guideline for any application related to geomechanics.
