Resumo: | |||||||||||||
The study of coupled phenomena in porous media has become essentialin predicting the behavior of geological media considering the increasinglycomplex scenario of energy extraction. Several ways of hydromechanical coupling have been presented in recent decades, also aiming to reduce the execution time of numerical simulations without impacting on the representationof geomechanical behavior in the flow in the porous medium. This workdeduces the coupling parameters necessary for the exchange of informationbetween a flow simulator and a geomechanical simulator, considering thethermal effects, anisotropy of elastic properties and compressibility of grains.In addition, a new coupling methodology is proposed and it capable of dynamically switch between two existing methods: iterative and sequential. Itis called adaptive coupling and is based on the behavior of coupling parameters during the iterative process. This methodology was verified by varyingspatial discretization, boundary conditions and permeability-porosity ratiousing both a single-phase and multiphase fluid neglecting thermal effectsand anisotropy of rocks. It was also evaluated the impact of the consideration of the surroundings rocks to the reservoir, grain compressibility andthe use of this methodology for a real case: Pituba field. Adaptive couplingachieved an average reduction of 35 percent in execution time with results close toiterative coupling and relative differences less than 5 percent. On the other hand,the sequential coupling which was also used in all cases presented obtaineda reduction of 50 percent, but with a higher differences.
