Exxon's concepts of Previous HitsequenceNext Hit Previous HitstratigraphyNext Hit developed from the stratigraphic interpretation of reflection seismic data, a technique known as seismic Previous HitstratigraphyNext Hit. Differentiation of chronostratigraphy from lithostratigraphy is critical in interpreting sequences on seismic data. Extensive experience indicates that reflections follow time lines in the rock record and that facies variations are recorded by lateral changes in reflection attributes. Integration of all available well, outcrop, and literature data in a seismic interpretation is essential to reducing the risks associated with predictions of play parameters using seismic Previous HitstratigraphyNext Hit.

Predictions based on seismic Previous HitstratigraphyNext Hit have been confirmed by drilling in frontier and developing areas. The level of stratigraphic detail needed from a seismic interpretation varies with technical and business objectives. The interpretation of Previous HitsequenceNext Hit sets may suffice to establish basin history, but seismic identification of individual sequences or system tracts may be required to establish plays and prospects. Even with little or no well control the presence, distribution, and continuity of individual reservoir and source units can be predicted using seismic Previous HitstratigraphyTop, as illustrated by applications in lacustrine and deep-marine settings.

Although limited by seismic resolution, detailed stratigraphic interpretations of thin intervals have significant impact on mature areas. The geometry and seismic attributes of even individual reflections provide critical data about reservoir distribution, reservoir continuity, and field segmentation, as illustrated by applications in reservoir modeling and reservoir management.
