The production of a petroleum reservoir is a coupled process between geomechanical and flow phenomena, which affect the reservoir and its surrounding rocks. Laboratory tests have shown that samples of a carbonate reservoir from Field B, an oil field located in the Campos Basin, are very sensitive to deformations caused by depletion. Thus, this study aims to assess production and geomechanical aspects of Field B development by different hydromechanical coupling schemes. Therefore, partially coupled hydromechanical simulations between the flow simulator IMEX and the geomechanical analysis software CHRONOS (a finite element code running on GPU) were performed using a methodology which allows either one-way or two-way coupling. A 3D Mechanical Earth Model of Field B was built in GOCAD, a geological modelling software, through a specific workflow for this task. Then, flow and geomechanical results were compared between one-way and two-way coupling simulations. Initially, permeability was not considered as a coupling parameter. In this case, there were no significant differences between the results. Afterwards, more two-way coupling simulations were performed, but at this time, considering variations of permeabilities due to depletion. The results of these new simulations diverged from the two-way coupling case in which permeabilities were kept constant throughout the simulation. Therefore, in this case, neglecting permeability coupling can lead to significant errors. Computational performance of the hydromechanical simulations performed along this Dissertation were also evaluated.
