The primary objective of this course is to gain an intuitive understanding of the kinds of seismic features that can be identified by 3D seismic attributes, the sensitivity of seismic attributes to seismic acquisition and processing, and of how ‘independent’ seismic attributes can are coupled through geology. We will also discuss alternative workflows using seismic attributes for reservoir characterization as implemented by modern commercial software and practiced by interpretation service companies.
Advanced 3D Seismic Interpretation
Top Learning Objectives
- Use attributes computed from interpreted time-structure maps to enhance subtle faults and folds
- Identify good and bad color display practices
- Display multiple attributes in a single image
- Apply color schemes that allow you to effectively communicate these features to others
- Identify the geological features highlighted by spectral decomposition and wavelet transforms
- Interpret spectral anomalies in the context of thin bed tuning
- Analyze singularities of seismic data for structural and stratigraphic details
- Evaluate the use of spectral information as a direct hydrocarbon indicator
- Evaluate alternative algorithms to calculate volumetric dip and azimuth in terms of accuracy and lateral resolution
- Interpret shaded relief and apparent dip images to delineate subtle structural features
- Exploit changes in amplitude variation with offset and azimuth to produce multiple-attribute images that illuminate different geologic features of interest
- Interpret attributes computed from multiple azimuth-limited seismic volumes to better characterize faults and fractures
