<p>Structural and statigraphic discontinuities are identified in a 3-D volume of seismic data samples (101) in the presence of reflection dip, by first selecting a primary (102) and at least one secondary direction (103) in the volume of seismic data samples. Next, skeleton patches are identified in the volume of seismic data samples, where the skeleton patches comprise groups of connected seismic samples representing seismic horizons in the volume of seismic data samples. Apparent dip is calculated in the primary and secondary directions at each data sample within the identified skeleton patches, creating a primary (104) and secondary (105) direction dip volumes, respectively, at corresponding data sample locations. A filter (106) is applied to the primary direction dip and secondary direction dip volumes to fill in values at the data sample locations not within the identified skeleton patches.</p> |
