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.
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.
Duration and Training Method
This is a classroom or virtual classroom course comprising a mixture of lectures, discussion, case studies, and practical exercises.
Participants will learn to:
- Interpret cores and well-logs in a sequence stratigraphic context.
- Review the basic terminology and definitions of sequence stratigraphy.
- Apply the concept of facies, facies stacking, and shoreline trajectory to define parasequences, surfaces, and systems tracts.
- Evaluate the main controls on depositional sequences.
- Describe the accommodation Succession Method and Sequence Stratigraphy Hierarchy.
- Apply the sequence stratigraphic method in non-marine, shallow marine, and deep marine environments.
The main topics covered in this course are:
- Sequence Stratigraphic Method Applied to Well Logs
- Sequence Stratigraphy Concepts
- Lithostratigraphy vs Chronostratigraphy Correlations
- Sequence Stratigraphy Method Applied to Well-Log
- Well-Log Interpretation Correlation
- Urdanetta Exercise - Well Log Interpretation and Correlation
- Well-Log Loop-Tie Interpretation and Mapping
- Well-log Interpretation and Correlation In a Production Setting
Who Should Attend and Prerequisites
Geophysicists, geologists, explorationists and managers who are interested in an introduction or review of the theory and application of contemporary stratigraphic techniques to exploration and production.
Vitor Abreu has 28 years of experience in the oil industry in petroleum exploration, development production and research, with a proven record in evaluating, risking and/or drilling in 22 countries and 31 sedimentary basins in the 6 continents. His areas of expertise include projects in exploration, development and production of deep water reservoirs, regional studies to define the petroleum system elements and key plays in frontier exploration, tectono-stratigraphic evolution of basins in different tectonic settings, maturing opportunities to drillable status, and play to prospect risking assessment. His experience in development and production includes several field studies in different depositional environments, with high-resolution stratigraphic interpretation integrated to engineering data to define reservoir connectivity and main baffles and barriers for effective field development plans. On research, Vitor is considered one of the world leaders on reservoir characterization of deep water systems, proposing new deep water models with strong impact in development and production.
Vitor has been an Adjunct Professor at Rice University since 1999, where he took responsibility for the course on Sequence Stratigraphy after Peter Vail’s retirement. He was the recipient of the Jules Braunstein Memorial Award (best poster presenta-tion, 2002 AAPG Annual Meeting) and was appointed AAPG’s inaugural international Distinguished Instructor in 2006. He is the current President-Elect of SEPM and has been organizing and chairing technical sessions at annual meetings for both AAPG and SEPM. More than 1000 students globally have taken his short course on “Sequence Stratigraphy for Graduate Students” since 2000. This course has been taught at annual meetings, international meetings, universities, and companies around the world. Vitor is the chief editor of SEPM’s “Sequence Stratigraphy of Siliciclastic Systems”, which has sold more than 3000 copies since publication in 2010.
