Oil and Gas
This is a practical introduction to the use of sequence stratigraphy to describe, correlate, and map strata. 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.
Duration and Training Method
A five-day classroom course with classroom lectures, discussions and exercises covering a wide variety of environments.
Participants will learn to:
- Characterize and map hydrocarbon play elements in different settings.
- Assess and interpret cores, well-logs, and seismic lines.
- Implement sequence stratigraphic methods to define plays and prospects, and to predict play element presence and quality on seismic data.
- Describe how the concepts of sequence stratigraphy were developed and apply the basic terminology and definitions of sequence stratigraphy.
- Apply the concept of facies, facies stacking, and shoreline trajectory to define parasequences, surfaces, and system tracts.
- Evaluate main controls on depositional sequences.
- Describe the Accommodation Succession Method and Sequence Stratigraphy Hierarchy.
- Apply chronostratigraphic techniques.
- Apply the sequence stratigraphic method in non-marine, shallow marine, and deep marine environments.
- Apply sequence stratigraphy in fine-grained environments.
This is a “hands-on” introduction to the concepts of Sequence Stratigraphy. This is a method developed to support geoscientists in the geologic interpretation of subsurface data, with the objective of predicting play elements, presence, and quality before drilling. The method can be applied to cores, well logs, seismic lines (2-D and 3-D), and outcrops in all depositional environments.

Who Should Attend and Prerequisites
This course is intended for petroleum geologists, geophysicists, reservoir modelers, seismic interpreters, reservoir engineers, petrophysicists and sedimentologists who require a working knowledge of the concepts of sequence stratigraphy.
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.
