SIMULATION OF COUPLED HYDRAULIC-MECHANICAL BEHAVIOR OF NATURALLY FRACTURED RESERVOIRS
A coupled geomechanics and fluid-flow double porosity model is developed to reproduce hydromechanical effects arising during the production of fractured reservoirs. The sensitivity to changes in stress may be more pronounced in fractured reservoirs because of their high hydraulic and mechanical heterogeneity degree. As the fractures constitute main flow pathways, the deformations they may suffer affect the overall field permeability and productivity. In the frame of the reservoir engineering, continuum approaches are used to simulate fluid flow in fractured rocks. However, geomechanics is required to account for more relevant parameters and to provide more realistic models. Our upscaled hydromechanical description of the reservoir blocks integrates fractures and matrix hydraulic and mechanical properties. Implemented in a reservoir simulator, the double porosity deformable model highlights overall anisotropic hydromechanical effects and their impact on reservoir productivity.
