Coherence Cube
The Coherence Cube quantifies the measurement of local waveform similarity within
a "global" aperture defined in space and time, utilizing dip and azimuth calculations.
The process provides accurate maps of the spatial change in the seismic waveform that
can readily be related to geologic features and depositional environments. Faults and
fracture systems can now be spatially imaged and directly mapped from the Coherence
Cube without the tedious and extremely subjective method of interpreting faults on
selected vertical sections, then connecting the interpreted segments to give a complete
fault picture. Depositional systems can be more readily understood as the process
highlights such depositional features as channels, onlap, turbidite sequences, etc. The
quality of the Coherence Cube result depends upon selection of optimum processing
parameters specifying dip constraints, temporal and spatial aperture and processing
algorithms.
