The Role of Sequence Stratigraphy in Previous Hit3-DNext Hit Characterization of Carbonate Reservoirs

Scott W. Tinker, Michael D. Brondos, and Lise Brinton

The product of Previous Hit3-DNext Hit reservoir characterization is a Previous Hit3-DNext Hit reservoir model. The integrity of the Previous Hit3-DNext Hit reservoir model is largely a function of the stratigraphic framework. Interpreting the correct stratigraphic framework for a subsurface reservoir is the most difficult and creative part of the Previous Hit3-DNext Hit modeling process. Sequence- and seismic-stratigraphic interpretation provide the best stratigraphic framework for Previous Hit3-DNext Hit reservoir modeling.

Depositional sequences are comprised of many petrophysically-distinct lithofacies regions. If each lithofacies region was uniform and homogeneous, it would be reasonable to use a lithofacies ("layer-cake") framework interpretation to distribute data in a Previous Hit3-DNext Hit model. However, lithofacies are typically time-transgressive, and often internally heterogeneous because geologic processes such as siliciclastic sediment deposition, sediment bypass, hardground formation, variable diagenesis, and facies shifts occur along depositional time surfaces on carbonate platforms. Therefore, a sequence stratigraphic framework interpretation, in which stratal geometries are honored, is better for controlling the distribution of petrophysical data in Previous Hit3-DNext Hit.

The role that sequence stratigraphy plays in the Previous Hit3-DTop characterization of carbonate reservoirs will be presented using two outcrop and four subsurface studies from the Paleozoic. The outcrop examples illustrate the important distinction between lithostratigraphic and sequence stratigraphic correlation, and the subsurface examples illustrate the process of quantification, integration, reduction, and analysis of geological, petrophysical, seismic, and engineering data. The concepts and techniques can be applied to carbonate reservoirs of any age.
