The growing exploration of challenging oil fields is followed by an increasing concern by members of the public and oil companies about environmental and safety issues. Studies of recent major accidents indicate that geomechanics analyses can be the key to prevent future incidents. Geomechanical effects can be very relevant during reservoirs analyses. Actually, there are many possibilities available to consider such effects, but iterative-coupled analysis has shown to be one of the best solutions because it presents accurate results in a feasible computational timeframe. The GTEP/PUC-Rio research group has developed a coupling program that manages both the flow simulator (IMEX or Eclipse) and the finite element solver (Abaqus or a faster in-house GPU solution called Chronos) in an interactive way. The mentioned program provides a wide-ranging solution for reservoir geomechanics. However, mesh generation, data preparation and results evaluations are bottlenecks for its application in the industry s work routine. This dissertation presents the development of a workflow included in a geological modeler to apply the coupled flow-stress for real hydrocarbon reservoir simulation. This workflow allows in a simple and direct manner the generation of a finite element mesh, the definition of mechanical parameters, the supervision of coupled solution execution and the evaluation of results (flow and stress) in a single viewing environment.
