Abstract

A seismic section is a complex mosaic of overlapping and often conflicting signals only a few of which are visible on conventional seismic displays. High angle signals such as migration artifacts and fault plane reflections are especially difficult to identify yet they are, for opposite reasons, often crucial to an interpretation. In the first part of this talk I will introduce several unconventional ways of looking at seismic data and show how even the cleanest seismic section contains far more information than we are used to seeing. In the second part, I will provide a real world example of how ignoring this information can not so subtly reverse many of the benefits of migration.

Biography

Dr. Steven Lynch received his B.Sc. with distinction in Biophysics from the University of Guelph in 1975 and his M.Sc. in Geophysics from the University of British Columbia in 1977. He returned to university and in 2008 received his PhD from the University of Calgary in the field of seismic visualization. Steve has spent most of his career developing software for such diverse fields as refraction statics, structural modeling and interpretation. In 1999, however, he switched his focus to seismic visualization after accidentally stumbling into SeisScape(tm) displays. Steve now manages the R&D department for Divestco's Software division and is reveling in the freedom of being an "empty nester".
