Geology of the southern North Sea diapers and pillows which acted as a buffer between structural segments. Triassic sequence fluvial sandstones are of lesser quality of a reservoir because it was not sealed in a trap such as the Rotliegend. Geology of the southern North Sea The North Sea basin is located in northern Europe and lies between the United Kingdom, and Norway just north of The Netherlands and can be divided into many sub-basins. The Southern North Sea basin is the largest gas producing basin in the UK continental shelf, with production coming from the lower Permian sandstones which are sealed by the upper Zechstein
