Sequence Stratigraphy - Basic Concepts and Applications. The sequence stratigraphic method was developed to support geoscientists with the geologic interpretation of subsurface data. This method is utilized to predict the presence of petroleum play elements and to assess their quality before drilling. Sequence stratigraphy is applied to core, outcrop, well logs as well as 2-D and 3-D seismic lines across all depositional environments. This course reviews basic definitions and terminology of surfaces and systems tracts and introduces the sequence stratigraphic hierarchy. Training exercises and datasets are thoroughly discussed, and participants later interpret subsurface data in non-marine, shallow marine, and deep-marine depositional settings within a sequence stratigraphic framework. Based on the sequence stratigraphic method, the recognition and mapping of play elements from exploration to production scales is emphasized in this course. Learning Outcomes: • Explain development of sequence stratigraphic concepts • Define basic sequence stratigraphic terms • Interpret facies and facies stacking patterns to map coeval depositional systems • Implement the concept of facies, facies stacking and shoreline trajectory to identify parasequences, systems tracts and stratigraphic surfaces • Differentiate the main controls on depositional sequences • Recall the sequence stratigraphy hierarchy • Interpret core, outcrop, well-logs, and seismic lines • Apply the sequence stratigraphic method in non-marine, shallow marine and deep marine environments • Recognize and map hydrocarbon play elements across different depositional settings
Course Content: • Lithostratigraphy vs. chronostratigraphy interpretations • Fundamentals of sequence stratigraphy • Well-log interpretation, correlation, and mapping • Seismic response of key stratigraphic surfaces • Seismic reflection termination mapping and seismic facies analyses • Accommodation succession method • Hydrocarbon play element recognition and mapping • Criteria and mapping strategies for play elements in non-marine, shallow-marine, and deep-marine depositional settings
