Fracture systems observed in naturally fractured reservoirs (NFRs) tend to be hierarchical (Figure 1): (1) regional faults going through the reservoir or forming the reservoir boundaries and in-field seismically mappable faults; (2) fracture corridors sometimes associated with faults and (3) background fractures. Vertically, background fractures tend to be impacted by mechanical stratigraphy while fracture corridors and faults usually cross-cut through the reservoir units (Figure 2). For fractured carbonate reservoirs, background fractures are usually more abundant but with much lower effective permeability than fracture corridors, and must be treated differently in a reservoir model.
