CARBONATES DATUMING DEPOSITS FACIES INTERPRETATION SEISMIC STRATIGRAPHY SEQUENCE STRATIGRAPHY
Seismic data contain a wealth of information if you know where and how to look for them. Using a number of seismic based examples and 'hands on" interpretation exercises from different geological settings worldwide, attendees will learn how to identify different depositional environments, predict facies, (especially reservoir, source rock and seal) measure water depths, calculate subsidence trends, recognize and quantify sea-level changes and, where appropriate, determine the paleo weather conditions. Issues of flattening and datuming to improve the understanding of basin evolution will also be addressed.
Upon completion of the course, participants will be able to:
- Understand the principles of Seismic Stratigraphy and apply them to the interpretation of seismic data
- Use seismic data to decipher basin evolution
- Apply techniques and ‘rules of thumb’ for lithological prediction using seismic facies variations, reflection geometries and geological models
Introduction and objectives
Seismic terminations and seismic surfaces
Seismic stratigraphic concepts and models
Seismic expression of relative sea-level changes
Sequence boundaries, systems tracts identification
Depositional environment prediction
Datuming, flattening and isopach abuse
Geoscientists, geologists and seismic interpreters, working in exploration or basin analysis, especially those interpreting seismic data with limited well control.
Participants should have a basic understanding of geology and depositional processes, as well as the reflection seismic method.
About the instructor
George Bertram is a geoscientist who has worked in the oil industry for over thirty years. During his career he has been involved in world-wide exploration with Exxon, Britoil and BP. In BP he ran the Stratigraphic Studies group and was responsible for modernising and teaching the in-house seismic stratigraphy course. After a spell as Technology Manager for Exploration he left BP in 1994 to set up Stratigraphic Research International. Since then he has built and run in-house core courses and workshops for many individual oil companies as well as teaching on behalf of JAPEC in London, I.P.A. in Jakarta, NCPGG and A.M.F. in Australia and the Nautilus Geotechnical Training Alliance in UK & US. He is currently an Associate Professor at I.F.P. in Paris and an Hon. Research Fellow at Glasgow University. His publications include articles on North Sea Geology, Trap Styles and Carbonate Development in the Maldives. He was co-editor with John Van Wagoner of AAPG Memoir 64 on Sequence Stratigraphy in Foreland Basin Deposits and he was also a co-author of the textbook fSequence Stratigraphyf. He recently contributed the chapter on Seismic and Sequence Stratigraphic Analysis in the Roberts and Bally publication fPrinciples of Geological Analysisf. In addition to teaching and organising fdesignerf workshops, he regularly consults for oil companies world-wide, project managing and assisting in interpretation, acreage evaluation, farm-in assessments and supplying advice on a range of general exploration matters.

Deep-water depositional systems form some of the largest petroleum reservoirs on Earth and represent the frontier of oil and gas exploration. However, deep-water depositional systems remain the least well understood because sediment gravity flows, including turbidity currents to hybrid and debris flows, are both infrequent and difficult to predict and monitor, setting them apart from sediment transport processes occurring on mountain tops to shallow marine settings. Therefore, modern seismic data, and, in particular, deep-water outcrops provide prime sources of stratigraphic data used to risk drilling targets and build reservoir models at every phase in the upstream exploration and production process. This course focuses on sub-bed-scale to field-scale architectural elements in deep-water depositional systems and how they affect the main risks in deep-water E&P across the value chain: reservoir presence, deliverability, seals and traps.

Sequence stratigraphy is now a well-established analytical tool for investigating sedimentary successions, with the aim of predicting the distribution of reservoir, source rock and seal lithologies. Over the last 20 years, concepts that were originally developed from seismic reflection data have been refined by application to wireline-log, core and reservoir production datasets.

Knowledge of the physical background of the preserved structures is a prerequisite to understand the mutual relations of structures found in cores that guide us in interpretation solutions and that help us to keep our imagination of the paleo-environment within realistic borders.
First the physical background of sedimentary structures produced by flowing water or waves is treated. These are the “building stones" of any depositional facies or depositional sequence. A proper and accurate interpretation of these in terms of bedforms and flow conditions is essential for understanding the origin and development of any depositional facies or depositional sequence.
After this focus is laid on special structures and vertical successions of structures that characterize fluvial, tidal and transitional fluvial-tidal environments. With transgression and regression, the facies of transitional sediments will move up and down the lower river reach. Recognizing these deposits is important as in sequence stratigraphy they permit a more precise determination of maximum flooding surfaces.
