This paper is focused on evaluating the potential of shear stimulation in enhancing productivity of low-permeability rocks using a computational modeling approach. In the adopted approach, fully coupled hydro-mechanical response of reservoirs with pre-existing fracture networks is simulated in a two-dimensional framework. A series of sensitivity studies have been performed in an initial attempt towards understanding how reservoir response to fluid injection is affected by some of the DFN characteristics and operational parameters such as injection rate.
