Seismic window

Abstract

Last week I watched a late night webinar (why are they always late at night?) which described using a “thalweg tracker” to map geological bodies in a 3D seismic data volume. Originally designed to follow the thalweg of a channel – here the thalweg is defined as the deepest / lowest part of a channel the tracker searches for the lowest point in neighbouring cells given a single seed point on an elevation map. The thalweg tracker will also work with seismic amplitude or several other seismic attributes as an input, and because the interpreter can select how many points are picked some control can be exercised to limit any picked bodies to a particular facies.
