Multiple Short Course Programme
Seismic Attributes and their Applications in Seismic Interpretation
|Discipline||Geology - Geological Modelling|
The course is divided into two parts: attributes review/applications and workflows. The first part starts with a review of seismic attributes and discusses the noise (random and coherent) reduction as one essential step of all attribute studies. The number of seismic attributes
increased dramatically causing confusion for geoscientists to select appropriate ones. A series of trace-based attributes, volumetric dipand azimuth, fault detection and enhancement attributes, volumetric curvature and frequency decomposition are presented in this course
and, for every attribute, a short theory will be followed by applications using examples from different sedimentary basins. Frequency decomposition is briefly presented with different decomposition methods such as wavelet transform, Fourier transform and matching pursuit analysis. Examples illustrate the interpretation challenges associated with frequency decomposition data interpretation.
The concept of multi-attributes and geobody extraction is introduced at the end of the first part of the course with examples on combinations of amplitude, phase, discontinuity and frequency attributes to visualize different geological objects. Iso-proportional slicing as a
powerful interpretation tool is discussed. In the second part of the course stratigraphic and structural workflows will be presented using the acquired attributes. The workflows (and the elements for their planning) aim to show the integration of several attributes for specific
interpretation purposes, with examples of stratigraphic (fluvial/shallow marine clastic systems, attribute expressions of deep water turbidites and carbonate settings) and structural imaging workflows.
Lastly, the course analyses the importance of the integration of seismic attribute analysis processes with the other seismic interpretation (qualitative or quantitative) workflows.
The course addresses geoscientists involved in exploration and production projects where seismic play a role and who wish to learn the basic theory of the main seismic attributes used in exploration and production, as well as their applications and how to integrate them in exploration and reservoir characterization studies.
Participants should have knowledge of seismic interpretation. Mathematical concepts of attributes are presented with minimum required equations and graphic illustrations. Some basic knowledge of seismic exploration may help.
