Abstract

Summary

The Northern North Sea is a complex, underexplored region with significant potential for hydrocarbon exploration. The Mesozoic rift basin has proven rich in hydrocarbons for the Jurassic and younger stratigraphic succession. Nevertheless, a comprehensive understanding of the Triassic stratigraphy and its potential for reservoir quality and CO2 storage is still lacking in the literature. The study area is at the limits between the Central North Sea and the Northern North Sea, and the Utsira High has played a key role in shaping the region’s stratigraphic evolution. This study aims to improve our understanding of the Triassic sedimentological evolution and palaeogeography of the Utsira High area throughout the Triassic rifting. By integrating seismic data, wireline logs, and core data, this work identified and mapped intra-Triassic packages and their lateral variations. The analysis presented here has been performed by integrating stratigraphic and biostratigraphic analysis, creating the basis for further and necessary understanding of the region. The results provide new insights into the long-standing nature of the Utsira High and its influence on sediment distribution. This study contributes to a better understanding of the North Sea Rift System’s evolution and has implications for reservoir development and CO2 storage
