Integrated analysis of seismic attributes (curvature and coherence), log imaging and core descriptions was the keypoint to the identification of a fracture family not recognized before in a naturally fractured reservoir in northeastern Colombia. The importance of this family lies in its high transmisivity of water that invades wells close to these corridors that need to be avoided in new wells to get maximum performance in hydrocarbon recovery. Quality of 3D data made possible to calibrate zones with 2D seismic and core data. Vertical zonation of fractures indicates facies and thickness control in this reservoir.
