Geologists and Geophysicists that spend most of their time interpreting seismic data on the workstation. Whether you are an early career geoscientist wanting to learn a systematic methodology for seismic interpretation or an experienced professional wanting to learn some of the latest techniques to have emerged in seismic stratigraphy, this is the course for you.
I.Introduction to seismic stratigraphy and how the science has evolved since the first-models put forth by the Exxon Research Labs, concepts of seismic impedance, resolution and detection, importance of using a scale during interpretation, checking data for processing errors and pitfalls.
II. Review of Sequence Stratigraphy in shallow and deepwater siliciclastic systems
I. Seismic sequence analysis: recognition and meaning of reflection terminations such as onlap, offlap, toplap etc. Seismic facies analysis and how reflection configurations can be used to interpret environments of deposition, risk of reservoir presence and quality, and net:gross.
II. Seismic Facies Analysis: external geometry, internal reflection configuration, variability in amplitude, interpretation of reflection continuity.
III.Exercises on performing sequence analysis on high quality seismic data from passive (trailing-edge) continental margins.
I. Seismic Geomorphology: Differences between seismic time slices, horizon and stratal slices, the workflow for interpretation, range of seismic attributes (spectral decomposition, curvature, etc), fluvial systems, shallow marine systems, deepwater systems, carbonates, mixed structural-stratigraphic trapping styles in channelized sandstone bodies.
II. Exercise on performing seismic sequence and facies analysis on instructor’s collection.
I.Seismic Imaging of Carbonate Platforms: biostromes vs bioherms, mounds vs reefs, atolls, build-ups, banks and platforms, identification of rimmed attached shelves, isolated platforms and ramps in seismic data, assigning Net:Gross values to different parts of carbonate platforms in seismic, effects of karstification and its seismic expression.
II. Integrating seismic interpretation with biostratigraphy: index fossils including planktonic and benthic foraminifera, calcareous nannoplankton, dinoflagellates, spores and pollen, the concept of ecostratigraphy, finger-printing and biosteering.
I. Morphology and differences between siliciclastic and calciclastic clinoforms, advection vs diffusion dominated clinoforms, measuring angle and height of clinoform, clinoform trajectory analysis: Bruhn’s Law, clinoform morphology, shelf vs shelf margin-clinoforms, siliciclastic vs carbonate clinoforms.
II. Workshop on participant data
A public version of this course is scheduled in Indonesia between July 12-16, 2021.
