Summary:
Outcropping analogs can provide key information on the 3D organization of fracture networks affecting carbonate reservoirs. Such information, however, needs to be integrated in a consistent work flow which includes i) 3D geometric model of the reservoir architecture, ii) mechanic modeling to determine areas of fracturing, iii) characterization of fracture networks, iv) determination of fracture-related permeability in small representative volumes and v) fluid flow simulations. Fracture networks have been recently analysed from km-scale pavements of the Jandaira Formation in NE Brazil. Combining images from a drone with outcrop analysis and thin section we present the first multi-scale characterization of the fracture field affecting the shallow water carbonates.
