Outcropping analogs and multiscale fracture patterns in the Jandaíra formation

Abstract

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 multiscale characterization of the fracture field affecting the shallow water carbonates.Geoscience & EngineeringCivil Engineering and Geoscience
