About the course: This workshop presents the concepts and practical applications of sequence stratigraphy for petroleum exploration and production. All concepts are illustrated with examples of seismic, well-log, core, and outcrop data. The exercises emphasize the recognition of sequence stratigraphic surfaces and systems tracts on well-log cross-sections, seismic lines, and outcrop profiles. This enables the practitioner to eliminate nomenclatural or methodological confusions, and apply sequence stratigraphy effectively for facies predictions in exploration and production.

Learning objective:

• To develop a thorough understanding of relative sea-level changes and their effect on the distribution of source and reservoirs rocks.
• To create an awareness amongst participants about the limitations of litho-correlation and the benefits of chrono correlation.
• To prepare participants for realistic facies modelling in the creation of geo- models.

Duration: 15+ hours
