Orientation and Distribution of Reservoir Fractures

Scattered wavefield analysis of 3-D seismic data volume in a fractured carbonate reservoir (Emilio Field). The left panel shows the interpreted fault locations (black lines) and the well positions (colored circles). The center panel shows the map migrated scattering index quivers.

The distribution of the quivers is an estimate of the fracture density in the field, while the orientation of the quivers gives an estimate of fracture orientation. The right panel shows the fracture spacing estimates obtained from spectral analysis of the scattered wave energy. For more information on the Scattering Index Method see Willis et al. (2006).
