  • Method for imaging discontinuities in seismic data using dip-steering
    Patent number: 6516274
    Abstract: Structural and stratigraphic discontinuities are identified in a 3-D volume of seismic data samples in the presence of reflection dip, by first selecting a primary and at least one secondary direction 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 and secondary direction dip volumes, respectively, at corresponding data sample locations. A filter 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.
