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.
Participants are invited to bring case studies from their workplace that demonstrates either the success or failure of seismic attributes to stimulate class discussion.
