  • Accurate modeling of production performance and recovery processes in petroleum and gas reservoirs is heavily influenced by the heterogeneity of natural geomaterials. Reliability of these studies regarding accurate estimation of the hydraulic properties of the reservoir rock stratum constitutes a challenging condition to be handled by the implementation of additive manufacturing (AM) technology. This fabrication technique is intended to provide a valuable tool not only for assuring heterogeneity and repeatability within the built specimens, but also to recreate specific properties of the reservoir rock and provide, in a foreseeable future, a suitable means to validate numerical models related to geomechanical in-situ processes. Therefore, for the purposes of emulating petrophysical and flux properties of a specific reservoir rock, it is imperative to recognize features arising from the AM process and their impact on printed specimens. By means of this project, a complete comprehensive analysis of the influence of printing configuration was accomplished to determine whether these variables influence the resulting hydraulic properties of the sandstone analogues. A complete range of petrophysical testing analyses were performed to evaluate the potential of 3D printed sandstone analogues to be a state-of-the art material at simulating the behavior of materials found in nature. Testing results demonstrate that additive manufacturing technology can be successfully used to generate sandstone replicas with properties and structure of the printed specimens interrelated with the properties of natural materials. However, some discrepancies on the range of values encountered for 3D printed materials compared with the properties of natural reservoir rocks remain. For instance, a direct comparison between common hydraulic values of Berea sandstone and manufactured materials has shown an increase of 41.6% on permeability values and of 44.3% on porosity for the 3D printed analogues.
