Clusters of deformation bands associated with fault damage zones modify the petrophysical properties of rocks and influence fluid migration. Many works discuss the influence of deformation bands regarding changes in porosity and permeability, but only a few address connectivity as a control of the fluid flow in porous media. We used digital outcrop models to perform a quantitative assessment of connectivity using a UAV-based system at the Melancias outcrop, Rio do Peixe Basin, Brazil. Topology determined the frequency, intensity and dimensionless intensity of deformation bands in three circular windows visually analyzed and interpreted. The geometry of the bands defines the proportion of node types, influences the distribution of I-, Y- and X-nodes, and controls the connectivity of fractures along the outcrop. Results provided by geometric and topological analyses corroborate connection per line as the more reliable connectivity indicator. Furthermore, they were crucial to defining the northeast sector as a corridor to fluid flow, whereas the other two sectors tend to be permeability barriers. We also analyzed the influence of trace lengths on the band network's overall orientation and geometric arrangement. For modeling and simulations purposes, the spatial relationships of nodes and branches help in the understand of potential hurdles to fluid migration and the variability of reservoirs and aquifers.
