Sequence Stratigraphy
This course introduces depositional systems and sequence-stratigraphic concepts, principles and methods of study for application to oil and gas exploration and development projects. An important emphasis in the course is the integration of seismic, well, and available engineering data to establish a sequence stratigraphic framework and map depositional facies. In so doing the sequence stratigraphy interpretation approach provides a powerful tool for predicting reservoir, source and sealing lithologies in the context of shelf to basin depositional environments. The sequence stratigraphy approach applies to regional, prospect, and field levels of scale and can play a key role in reservoir characterization and predicting reservoir size, geometry, and heterogeneity. The course presents techniques for the definition, age dating and correlation of rock units and the recognition of depositional system responses to changes in relative sea level as reflected in the stratigraphic record. Lithostratigraphy, chronostratigraphy, and sequence stratigraphy are practiced through exercises and the advantages and disadvantages of their application are discussed. Data analysis techniques will demonstrate seismic sequence correlation, seismic facies analysis, and mapping calibrated to well log responses and biostratigraphic indicators to identify depositional patterns and sedimentary facies relationships. Both siliclastic and carbonate environments are considered. Participants will understand depositional system classifications and sedimentary facies environments, gain insights on temporal and spatial scales of resolution from data integration for age calibration and correlation, develop a sequence stratigraphic framework based on lithostratigraphic and chronostratigraphic principles, relate relative sea level changes and eustasy to sequence cyclicity and facies patterns, define key stratigraphic surfaces from seismic, well log, and biostratigraphic data, and interpret seismic reflection geometries and construct seismic facies maps. Students will also learn how to identify depositional system tracts in a sequence stratigraphic framework, relate sequence stratigraphic correlations and mapping to basin architecture and depositional environments, predict reservoir, source, and seal lithologies from stacking patterns and depositional facies mapping, recognize lateral facies relationships and reservoir heterogeneity.
