Abstract
Fractured rocks usually provide high permeability pathways for hydrocarbons. Unfortunately, fractures are difficult to image using seismic waves because they are below the typical seismic resolution. The majority of the prestack fracture detection methods, based on P-wave reflection data, use either amplitude variation with angle and azimuth or travel-time changes.
