Well Log Sequence Stratigraphy for Exploration and Production
Sequence Stratigraphy is a method developed to support geoscientists in the geologic interpretation of subsurface data, with the objective of predicting and mapping play elements' (reservoir, source/charge, seal) presence and quality before drilling. The method can be applied to cores and well logs in all depositional environments. This course will review the basic terminology and definition of surfaces, systems tracts, sequence sets, and stratigraphic hierarchy. The method will be described and applied to interpret subsurface data 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.
Business Impact: Participants will develop an understanding of how sequence stratigraphy aids in prediction and mapping of play elements' presence and quality based on well data. 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.
