Seismic Attributes
Seismic interpretation often relies on “attribute” sections and 3D images.
Attributes are secondary properties derived from pre-stack reflection data or (more often) from the images themselves:
nInstantaneous (local) amplitudes,
phases, frequencies, bandwidths, etc.
nLocal dips and velocities
nStatistical coherency attributes
(especially useful in 3-D for tracing faults)
nAmplitude versus Offset attributes
