Paper presented at the ISRM International Symposium – EUROCK 2021, September 21–24, 2021
Paper Number: ISRM-EUROCK-2021-112
... Abstract This work presents a numerical framework, for the analysis of coupled fluid and geomechanical processes related to subsurface operations, built upon ABAQUS of SIMULIA, an industrial-standard software for mechanical analysis, and Echelon, a GPU-based reservoir simulator. By using...

... properties is presented describing how the properties can be estimated. In the end, we offer suggestions on how to couple the hydromechanical processes in order to evaluate the possibility of fault reactivation. 1 INTRODUCTION 1.1 Generalities The presence of faults is expected to affect the flow of fluids...

... of reactivation and possible loss of tightness of the reservoir. Thus, the aim of this study was assess reservoir models with a fault zone using partially coupled hydro-mechanical simulations. The methodology considers a fault zone whose behavior is given by the Mohr-Coulomb yield criterion. The plasticity model...

...-controlled testing machines. It was also found that the effect of coupling between elasticity and plasticity exists in some of the specimens, although for other specimens no such result was obtained. These results show that the coupling effect is the feature that connected both testing conditions and failure...

... ABSTRACT: For a fractured rock, the coupling between thermal, hydraulical and mechanical behaviour requires alternative means of evaluation in discontinuous rocks than the ones used for porous media. In this paper, the case of a gallery containing high level nuclear waste and connected...
