Spectral decomposition was applied to generate spectral sections at low-frequencies (10 to 35 Hz), and to create a spectral map at 10 Hz along the T ilje Fm top. A coherency attribute has been determined from the seismic data to enable fault interpretation in the study area. T his study addresses the question of whether the presence of low-frequency anomalies can indicate a hydrocarbon-bearing reservoir in an area with a high density of faults.
