This enables the practitioner to eliminate nomenclatural or methodological confusions, and apply sequence stratigraphy effectively for facies predictions in exploration and production. The points of agreement and difference between the various sequence stratigraphic approaches (models) are discussed, and guidelines are provided for a standard process-based workflow of sequence stratigraphic analysis. o Topic 3: Transgressive-regressive sequences.o Topic 2: Genetic stratigraphic sequences.Exercise: Identification of systems tracts on 2D seismic data and well-log cross-sections.

In some of the literature “sequence” has been used as a synonym for “succession”, and it has been employed for cyclic or unconformity-bounded units of varying dimensions and for time spans ranging from thousands of years to hundreds of millions of years. Sloss (1963) defined stratigraphic sequences as “rock-stratigraphic units of higher rank than group, megagroup, or supergroup, traceable over major areas of a continent and bounded by unconformities of interregional scope.” This useage has not received universal acceptance. However, the term sequence has had a checkered history. bounded at its top and base by unconformities or their correlative conformities”. It is a “stratigraphic unit composed of a relatively conformable succession of genetically related strata. The currently accepted definition of “sequence” is that proposed by Vail et al.
