What is a seismic terrain? A spectacular aerial view of surface outcrop terrain (Figure 1) shows the plunge of an anticline rimmed with flatirons. The field geologist can ascertain, at a glance, the dip and frequency of bedding and can gain an immediate sense of underlying structure. This experience is very similar to that gained by viewing a 3-D seismic terrain generated from time-slice instantaneous phase (Figure 2). Creating a seismic terrain map or 3-D visualization is a simple technique done with little or no interpretation other than extracting phase data and transforming them into two-way...
