Abstract: Previous HitSeismicNext Hit stratigraphy into the next millenium; a focus on 3D Previous HitseismicNext Hit data

Previous HitSeismicNext Hit stratigraphy may be defined as the study of stratigraphy using Previous HitseismicNext Hit data. Analysis of stratigraphic architecture based on reflection terminations, and identification and mapping of Previous HitseismicNext Hit facies patterns as imaged on 2D Previous HitseismicNext Hit profiles, have long constituted the Previous HitseismicNext Hit stratigraphic approach. However, since then, especially during the last decade, there has been a virtual explosion of 3D Previous HitseismicNext Hit volumes. These data sets offer the potential for quantum leaps forward in the understanding of how basins fill. 3D data offer the potential for directly imaging discrete elements of entire depositional systems. Although Previous HitseismicNext Hit resolution decreases with depth, a broad range of depositional elements can nonetheless be imaged from the sea floor down to basement through analysis of a combination of Previous HitseismicNext Hit reflection and Previous HitseismicNext Hit interval attributes. Integration of 3D-based analyses of the spatial and temporal distribution of depositional systems with classical sequence stratigraphic concepts will elevate these concepts to the next higher level. Stratigraphic and geomorphologic insights derived from 3D Previous HitseismicNext Hit volumes will in some instances revolutionize and in some instances modify or confirm our understanding of how basins fill. In order to maximize the potential stratigraphic insights afforded by 3D data, the interpreter's required skill set must evolve from an understanding of stratigraphic architecture to an understanding of paleo-geomorphology and depositional systems. Some of the most useful images derived from 3D Previous HitseismicNext Hit volumes are observed in plan view and illustrate discrete landforms. The emphasis of Previous HitseismicNext Hit stratigraphy consequently will shift from exclusively identifying stratigraphic discontinuities and discrete Previous HitseismicTop facies, toward direct identification of depositional elements that depend on plan view interpretations.
