Seismic Structural Styles Workshop

Format and Duration
5 days

Summary

This hands-on workshop offers unique treatment of the subject of structural styles, including new concepts and advances in structural geology. It introduces the underlying conceptual and experimental models behind structural interpretation and then builds interpretation skills by applying the models to increasingly complex or poorly imaged seismic data. Topics include interpretation of extensional, compressional, strike-slip, inversion, gravity-driven systems, igneous events and salt and shale structures.

Feedback

This is an excellent course! My understanding of seismic structural styles has increased 10-fold this week alone! Very enjoyable classroom climate & exercises.

Duration and Training Method

This is a highly interactive and participatory five-day classroom course oriented towards problem solving rather than theory. It contains short lectures interspersed with seismic interpretations exercises, discussions, and experimental models. Participants are encourage to bring samples of problem data for group discussion.

Course Overview

Participants will learn to:

  1. Use structural analysis tools such as regional elevation, recognizing growth layers, fault-fold relationships, rigid body and internal deformation, recognizing detachments and ductile layers to constrain interpretations.
  2. Demonstrate common pitfalls in structural interpretation.
  3. Understand the impact of detachments and ductile layers on structural styles.
  4. Explain the theoretical and empirical basis for structural models of extension, compression, strike-slip, inversion, salt and shale deformation.
  5. Distinguish key differences in structural styles.
  6. Apply lessons learned about structural styles to both good and poor data.
  7. Apply the concepts of restoration and forward modelling and employ them in interpretation.
  8. Analyze pre-existing structural interpretations.
  9. Interpret gravity driven systems, along with intrusive and extrusive igneous events in seismic data.

Classroom discussions focus on evaluating seismic data that deviate from idealized models and how and when to apply simple structural models. Exercises, physical models and lectures focus on  how to best delineate structures, determine timing, and evaluate exploration risk.

Basic Structural Tools

  • Vertical Exaggeration
  • Recognizing Ductile Layers and Detachments
  • Packaging Tectonic-Lithic Events
  • Translation and Rotation
  • Introduction to Internal Deformation, Forward Modeling, and Restoration
  • Regional Elevation
  • Recognizing and Predicting Growth Layers

Extensional Structures

Compressional Structures

Strike-Slip Structures

Inversion Structures

Salt Structures

Shale Structures

Linked Extensional and Compressional Systems

Igneous Events

This course is appropriate for both early-career and experienced geoscientists. They should be familiar with basic interpretation methodology at least college-level structural geology.

The course incorporates new ideas in structural geology and so will also benefit the more experienced interpreter who is working in a new structural regime or who desires a refresher course that covers recent developments in structural geology.
