Reflection Seismology

Dr. Derek Sawyer [ES 5780]

COURSE TOPICS INCLUDE:
• Theory of sound wave propagation through the Earth
• Acquisition • Processing
• Fundamentals of seismic stratigraphy and interpretation
• Hands-on instruction with 2D and 3D seismic data
• Integrating with core and log data  • The all-important well-tie
• Making maps and cross-sections  • Making maps and cross-sections

  • Seismic data is the standard tool for imaging subsurface geology in the upper ~10km of the Earth’s surface with applications in oil and  gas exploration, gas hydrates, environmental imaging, sedimentary basin analysis, and crustal structure for tectonophysics research. The audience for this course includes those interested in exploration, those looking to more fully understand multi-channel data analysis, as well as those interested in the detection and characterization of fluids in the subsurface.
  • The interpretation component will include hands-on training with professional programs IHS KingdomSuite and Schlumberger Petrel in the Kresge computer laboratory. Students develop marketable skills with how to work with 2D and 3D seismic data including mapping and visualization of stratigraphy and structure as well as techniques for tying seismic to core and log data.
  • The class if offered annually, typically in the fall, with lectures M-W-F 11:30am-12:25pm.
  • In addition to lectures, labs will occur Monday and Wednesday afternoons 3-4:30pm in the Kresge computer lab (356 Mendenhall). Labs are an important part of the course and are not simply check-the-box assignments. Labs are designed to give the student a progressively deeper understanding of seismic data interpretation. As such, attendance at each lab session is essential. I and the TA will be present at each lab session to answer questions and provide guidance. There are a total of 7 2-week lab assignments throughout the semester. Each student will be able to work on their own computer, however group discussion is valuable and encouraged.
  • Fridays will be used for interpreting new seismic data in a group setting. The only requirement is attendance and participation! These are valuable opportunities for seeing and interpreting new seismic data from various geologic settings around the world and to apply concepts from lecture.
  • Finally. each student will also work throughout the semester to complete a seismic interpretation project of their own choosing and present their results as a poster presentation at the annual holiday school holiday and poster presentation day.
