We address numerically the effect of thickness variations of low-permeable deformation bands in sandstones reservoirs. Such thickness variations have previously been considered as significant for controlling how deformation bands affect fluid flow. Here, we show that (i) on the scale of flow across individual bands, thickness variations may have minor effects; (ii) on an aquifer/reservoir scale, the effects of deformation band thickness variations are negligible; (iii) deformation band connectivity and permeability, not thickness variations, are important.
