Geomechanical analysis is essential to assess the productivity forecast of Cyclic Steam Stimulation (CSS) operations in heavy oil reservoirs. The high-temperature and high-pressure fluid injection, as well as depletion in unconsolidated and poorly cemented porous media during CSS, may generate a relevant stress-strain response at levels that can lead to irreversible changes in reservoir permeability. Therefore, considering permeability dependent on rock strain is fundamental to properly analyze the impact of geomechanics, pressure, and temperature on reservoir performance. In this paper, a proposed directional strain-dependent permeability model is implemented to assess productivity and compare it with a conventional volumetric permeability model through numerical simulation, considering the effects of wellbore creation on the stress-strain initial state. An explicit coupling between CMG-STARS and the geomechanics in-house simulator GSIM is carried out to perform the simulations...
