# Case study **Visualising subsalt structures in the North Sea **

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.

The overlying Zechstein Super Group acts as an incredible seal for these structures, but also poses several imaging issues for the underlying reservoir.  

[In this case study](https://www.geoteric.com/subsaltnorthsea-case-study#downloadform) we show how Geoterics’ AI Fault Analysis can aid in the detection of subsalt structural lineaments in the Southern North Sea and the implications for other basins around the word.
