As oil and gas E&P is moving towards more mature phases, innovative new approaches are needed in petroleum geology. To find additional reserves in mature exploration areas and to improve production in existing fields, a better understanding of the spatial distribution and time-stratigraphic framework of the potential reservoirs and seals is needed. To meet these challenges, existing conventional stratigraphic methods have been improved and new stratigraphic concepts have been developed during the last decade. Amongst one of the most important concepts which have been proposed by the Exxon school a decade ago was sequence stratigraphy. Nowadays, sequence stratigraphy is widely applied in subsurface correlations and is becoming a routine practice. Sequence stratigraphy can best be seen as the delineation and correlation of changes in depositional trends that are generated during a base level cycle (see Embry, 2002). Despite the constant modification and improvement of the sequence stratigraphic concept, it did not reach an important objective – the construction of a near- synchronous stratigraphic correlation framework. One of the main reasons is the strongly model-driven approach of sequence stratigraphy which is preventing to construct an objective and reproducible correlation framework.
