This project and its resultant report presents heavy mineral provenance data from the Early Triassic Bunter Sandstone Formation. Together with the other projects that comprise the CASP Bunter Sandstone Storage Complex Thematic Research, this project forms part of the first regional scale appraisal of the Bunter Sandstone Formation across the Southern North Sea.

This study focuses on a unique onshore well from the northeast of England, which provides a fully-cored section through the entire ~270 m thickness of the Bunter Sandstone Formation, as well as nine wells from across the UK and Dutch sectors of the Southern North Sea. The analytical dataset comprises, 147 conventional heavy mineral analyses that are supplemented by a subset of 30 single grain geochronological and geochemical analyses (apatite U-Pb and trace elements, zircon U-Pb, garnet major elements, and tourmaline major elements).

The results provide essential data enabling the prediction of reservoir quality, as well as a refined understanding of the geological framework of the reservoir interval across the Southern North Sea.

Delivery of data

The data and its interpretations are provided as both a physical and electronic report of 147 pages, together with an accompanying GIS.

Completed: December 2024
