Business Impact: Students will gain the skills required to select and apply a broad range of seismic attributes including combined attributes in exploration and reservoir characterization projects.

Lecture and exercise materials cover interpretation workflows using attributes currently available on most modern workstations as well as recently developed seismic applications designed to extract the smaller scale geologic details required for the construction of reservoir models.  

Duration and Training Method

A virtual classroom course divided into 10 three-hour long webinars sessions over a two-week period (equivalent to a five-day classroom course) using lectures, data examples, case studies, and exercises.

Participants will learn to:

  1. Review seismic wave fundamentals including the convolutional model, tuning, phase and understand the importance of maximizing seismic bandwidth.
  2. Assess the role of post stack attribute tools commonly found in most workstation software in seismic interpretation workflows. Examples include the use of max/min amplitude, instantaneous frequency/phase, curvature, coherency and dip/azimuth attributes as structural or stratigraphic indicators.
  3. Evaluate the role of AVO (amplitude vs. reflection angle) measurements to address specific interpretation problems including fluid prediction and the estimation of elastic rock properties.
  4. Investigate the use of spectral enhancement attributes such as Sparse Layer Inversion in interpretation workflows.
  5. Appraise the use of geo-statistical tools, spectral decomposition, and multi-attribute analysis in reservoir characterization.
  6. Recognize the limitations of AVO tools, post stack inversion, and other seismic attributes.
  7. Develop fit-for-purpose interpretation workflows for several exploration and production problems in the classroom.

Who should attend

This course has been designed for geoscientists possessing; 1) a basic understanding of the fundamentals of seismic technology including data processing, 2) having a minimum of three years experience interpreting 3D seismic data, and 3) who are interested in learning more about the application of seismic attributes to achieve exploration, reservoir characterization and production objectives.

Prerequisites and linking courses

A basic knowledge of the seismic method, including data processing, is required for everyone taking this course. Courses such as N085 "Introduction to Seismic Interpretation", or N080 "Geophysics for Subsurface Professionals", or N376 "Seismic Data Processing: Principles and Best Practices" are recommended precursors for people with limited knowledge of the seismic method.

John Castagna

Dr. John P. Castagna, a research geophysicist with extensive industry experience in petroleum exploration and development, came to the University of Houston in 2003. Previously, he was a professor for eight years at the University of Oklahoma. Prior to that, he spent 16 years working for Atlantic-Richfield Corporation in a variety of research, operations, and management positions.

In 1995 he served as Distinguished Lecturer for The Society of Exploration Geophysicists. He has served the SEG in various other capacities including: Chairman of The Leading Edge editorial board, Vice-President, Technical Program Chairman, and from whom he received the Reginald Fessenden Award for Technical Achievement. His book, Offset-Dependent- Reflectivity: Theory and Practice of AVO Analysis, is an SEG bestseller.
