Exxon's concepts of sequence Previous HitstratigraphyNext Hit developed from the stratigraphic interpretation of reflection Previous HitseismicNext Hit data, a technique known as Previous HitseismicNext Hit Previous HitstratigraphyNext Hit. Differentiation of chronostratigraphy from lithostratigraphy is critical in interpreting sequences on Previous HitseismicNext Hit 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 Previous HitseismicNext Hit interpretation is essential to reducing the risks associated with predictions of play parameters using Previous HitseismicNext Hit Previous HitstratigraphyNext Hit.

Predictions based on Previous HitseismicNext Hit Previous HitstratigraphyNext Hit have been confirmed by drilling in frontier and developing areas. The level of stratigraphic detail needed from a Previous HitseismicNext Hit interpretation varies with technical and business objectives. The interpretation of sequence sets may suffice to establish basin history, but Previous HitseismicNext Hit 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 Previous HitseismicNext Hit Previous HitstratigraphyNext Hit, as illustrated by applications in lacustrine and deep-marine settings.

Although limited by Previous HitseismicNext Hit resolution, detailed stratigraphic interpretations of thin intervals have significant impact in mature areas. The geometry and Previous HitseismicTop 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.
