Coherency filtered seismic sections provide excellent models for estimating residual statics, especially for deep crustal data with low signal to noise. A second coherency filter pass following residual statics collections provides even better structural clarity than is seen on sections with only a single coherency filter pass. Benefits of the technique include: increased lateral extent of individual reflections resulting in fewer isolated events, uniform wavelet shape throughout the section, and an increase in the number of detected events over line drawings. This processing flow results in appealing visual displays and may provide new information on structural complexities not recognized in line drawings based on the input data alone.
