3D Seismic Attributes for Reservoir Characterization - SARC
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. Participant discussion centered around case studies, attribute recipes for particular objectives, reservoir workflows and seismic attribute jeopardy exercises will be the main focus of the course.
Seismic interpreters, processors, stratigraphers and structural geologists, reservoir engineers, and students of geophysics.
You will Learn:
Participants will learn how to:
- Use attributes to enhance subtle faults and folds, as lithologic indicators, and quality control the choice of processing parameters.
- Evaluate and exploit attribute expressions for different depositional environments to better characterize reservoirs by adopting appropriate workflows and multiattribute tools.
- Identify geological features highlighted by attributes, limitations to seismic processing through attributes that may result in smeared attribute images from multiazimuth and multioffset data, limits of attribute analysis on data that have been poorly imaged and good and bad color display practices.
