Determining mechanical properties of reservoir rocks through mechanical testing is a well-established procedure. Static properties obtained from these tests (Young's modulus, Poisson's ratio, UCS, etc.) are fundamental to calibrate both ID geomechanical models (well-scale) and complex 3D models (reservoir-scale). These mechanical lab tests have the disadvantage of being destructive, making it impossible to obtain large amounts of data and limiting the generation of geomechanical reservoir models. In this context, numerical simulations of laboratory tests can be a good alternative to obtain mechanical properties of rock without the expensive destructive testing. In this paper, we present a methodology based on numerical simulations and image analysis (thin sections and/or micrographs of cores) to model the mechanical properties from Brazilian tests simulations. The developed methodology reproduces in the simulator the mineralogy, the texture and the structure of the rock to improve the understanding of the distribution of the mechanical properties of the formations. The results are in good agreement with mechanical lab tests. Copyright 2015 ARMA, American Rock Mechanics Association.
