What I like the most is that opendtect is really easy for seismic interpretation. Picking horizons is a really straightforward process, even diagraming faults is easy. Plus working with seismic attributes and applying them to the horizons or the whole volume allows for easier and more precise interpretations. Review collected by and hosted on G2.com.

It's paid version is expensive while the free version is really limited. Also the seismic attributes are not that accurate. It requires a good graphic card or else is not going to work smoothly. When interpreting the horizons you have to create a grid with an offset, and when this offset is small it can go really slow. Review collected by and hosted on G2.com.
