Methodological study demonstrates 3-D seismic discontinuity mapping via coherence cubes in subsurface imaging, highlighting direct detection of fault surfaces without recorded fault reflections.

Key Points

To introduce a seismic processing method that generates 3-D volumes of coherence coefficients to directly map structural discontinuities such as faults and stratigraphic features.
Processed 3-D seismic reflection data using an algorithm that calculates localized coherence coefficients across spatial dimensions.
Constructed a 3-D volume (coherence cube) to isolate seismic discontinuities and numerically delineate fault boundaries.
Compared coherence cube time slices with conventional 3-D seismic reflection amplitude time slices.
The coherence cube successfully imaged fault surfaces as numerically separated boundaries within a 3-D volume.
Discontinuities and stratigraphic features were delineated clearly even when no direct fault plane reflections were recorded in conventional amplitude data.
