I've been developing OpendTect workflows to support my graduate student's research and my University of Arkansas course 3D Seismic Exploration. These are posted and maintained on my Grad Student Blog and links to those blog entries will be given here and updated as new workflows come online.
These may be of some use to those academics and others out there using OpendTect for teaching, research, hydrocarbon exploration or any other application of seismic interpretation.
