Abstract

Instantaneous-phase is the optimum attribute to use in horizontal seismic time slices for rapid, accurate 3-D structural mapping, because of its enhancement of event continuity. Instantaneous-phase slices also provide the interpreter with the most precise display for directly interpreting spatial relationships between seismic sequences, by reasoning analagous to that used to interpret geological maps. In contrast, amplitude time slices lack precision because weak events are lost by scaling, and wavelet phase points can only be crudely estimated.
