Although seismic processing continues to advance, imaging subsalt
structures still presents a challenge . With new licence rounds opening in
regions such as offshore Brazil, the potential prize for accurately
interpreting these structures is a great one.

The Rotliegend Sandstone is the primary hydrocarbon reservoir of the Southern North Sea and forms structural highs as a result of multiple episodes of faulting. This has led to several structural traps, in the form of tilted fault blocks and inversion monoclines, as seen in the Ketch Field area.
