The Stark Reality Surface Segments plugin expands on the Surface Slice process described by Stark (1991, 1996). It is typically applied prior to interpreting seismic horizons. It implements a trace-by-trace process that exposes the inherent spatial continuity (or lack thereof) of seismic horizons by producing map segments of events that intersect each Z-slice. Depending upon the user selected parameters, horizontal slices through the Surface Segments volume indicate the spatial variations of local dip magnitude and direction, local strike, discontinuity locations, and/or horizon amplitude variations along horizon segments. The stratigraphic relationships of vertically adjacent horizons can also be obtained from Surface Segments displays. All of this is obtained without requiring any pre-processing or interpreted horizons.
