Geert de Bruin,* Kirstin McBeath, and Nanne Hemstra show how recently introduced software could be the key to greater use of seismic sequence stratigraphy. In essence, sequence stratigraphy is used to provide a chronostratigraphic framework for correlation and mapping and for stratigraphic prediction (Emery and Myers, 1996). Although, sequence stratigraphy has proven to be a powerful instrument, and despite major advances in concepts since its introduction in the 1970s, sequence stratigraphy has not lived up to its potential because of the lack of supporting software tools. Recently a new software system, OpendTect SSIS, came to the market with the aim of filling this gap. The basic concept of OpendTect SSIS is that all stratigraphic events (horizons) are auto detected by the system and placed into stratigraphic order (Ligtenberg et al., 2006; de Bruin et al., 2006; and de Groot et al., 2006a, 2006b). These chronostratigraphic surfaces are generated at sub-seismic resolution and tracked throughout the seismic volume within the limits of conventionally mapped bounding surfaces. They are assigned relative geological time indices, or ‘geotimes’.
