Seismic Structural Analysis Seminar (co-taught with M. Withjack and P. Hennings)

An integrated course that taught seismic interpretation together with geometric analysis of structures and restoration techniques (5 day course).

Interpretation of Compressional Structures Field Seminar (co-taught with P. Hennings and J. Wickham)

Field-based seminar that taught the concepts of seismic interpretation, extrapolation of surface data to depth, cross section construction, and petroleum system analysis in compressional tectonic systems (10 day course presented yearly in Wyoming, Montana, and Alberta, Canada).

A course that taught the recognition and mechanics of structures formed by fault reactivation. Course centers around exercises using seismic, field, and experimental data to illustrate the range of structural geometries of inversion structures and their impact on the petroleum system (3 day course offered yearly in Dallas).

Restoration and Geometric Analysis (co-taught with M. Withjack and P. Hennings)

A course that taught the fundamentals of restoration and geometric analysis of structures. Exercises and lectures are designed to apply these techniques to seismic interpretation in salt, extensional, compressional, and inverted provinces (3 day course presented in Stavanger, Norway (1994), Dallas, Texas (1994, 1995, 1997) and Kuala Lumpur, Malaysia (1996)).

Introduction to Physical Modeling (co-taught with M. Withjack)

A course that taught participants to critically evaluate the results of experimental studies and to apply the results to their own work (2 day course taught in Stavanger, Norway (1994) and Dallas, Texas (1994)).

Introduction to experimental modeling of tectonic processes (co-taught with B. Vendeville and M. Withjack)

2-day course offered at Geological Society of America for 1995 Annual Meeting in New Orleans,

and at American Assoc. Petroleum Geologists for 1997 Annual Meeting in Dallas.
