Oil and Gas
Oil and Gas | Geophysics and Seismic Interpretation
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.
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.
Participants will learn to:
- 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.
- Demonstrate common pitfalls in structural interpretation.
- Understand the impact of detachments and ductile layers on structural styles.
- Explain the theoretical and empirical basis for structural models of extension, compression, strike-slip, inversion, salt and shale deformation.
- Distinguish key differences in structural styles.
- Apply lessons learned about structural styles to both good and poor data.
- Apply the concepts of restoration and forward modelling and employ them in interpretation.
- Analyze pre-existing structural interpretations.
- 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.

Who Should Attend and Prerequisites
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.
Gloria is an international consultant in structural geology, with 30 years of experience in the oil and gas industry. Gloria began her work in the industry at Mobil’s Research Lab and Exploration Technology Company where she worked for 11 years as a researcher, internal consultant and technical teacher. She has been an independent consultant since 2000. Her primary research and consulting areas are the interpretation and analysis of complex 2D and 3D seismic data, compressional and inversion structures, salt/shale gravity- driven systems, the use of physical models to understand structural deformation, and cross section restoration. She has been teaching Nautilus courses since 2004.
