Sequence stratigraphy provides a deterministic framework for understanding facies and ultimately reservoir architecture. It provides a framework for building reservoir models based upon logical, testable geological principles. This framework allows prediction of connectivity of flow units, distribution of major permeability barriers and systematic changes in sand body architecture. Zonation of reservoir models into genetically related packages of strata (such as parasequences or systems tracts) allows zones to be populated with predictable facies trends. These facies then form the basis for the distribution of petrophysical parameters within the reservoir. Sequence stratigraphy also provides a reality check for stochastic models.
