Sequence Stratigraphy Applied to Exploration and Production
Participants will learn to the use sequence stratigraphy to describe, correlate, and map strata, enhancing geoscience workflows throughout the E&P life cycle. They will enhance value for their employers by identifying high- and low-risk areas, generating robust resource volume assessments, and providing an interpretation of connectivity that allows for more accurate prediction of production.
The terminology of surfaces, systems tracts, sequence sets and stratigraphic hierarchy will be described, and then applied to subsurface data exercises in non-marine, shallow marine, and deep marine depositional settings. The emphasis will be on the recognition and mapping of play elements from exploration to production scales. The sequence stratigraphic method can be applied to cores, well logs, seismic, and outcrops in all depositional environments.
