CASP today announced the release of their latest report: “Composition and Sealing Capacity of the Haisborough Group in the SM14 Borehole, North Yorkshire, UK: A Reference Well for the Southern North Sea.”

This comprehensive report presents an integrated sedimentological, geochemical, and petrophysical analysis of the Middle to Late Triassic Haisborough Group. The study is based on data from the continuously cored SM14 well in North Yorkshire, which is located relatively far from the Triassic basin margin, making it ideal for comparison with offshore stratigraphy.

Key Highlights:

Scope of Study: SM14 offers an unparalleled dataset, thanks to an extensive observational and analytical programme. The report provides critical insights into seal integrity for the Bunter Sandstone Storage Complex.

Detailed Sedimentary analysis and revised lithostratigraphy: A 285 m sedimentary log, facies analysis, and a revised lithostratigraphy for the Haisborough Group are presented. Sixteen lithofacies were identified, grouped into ten lithofacies associations, which are presented alongside industry-standard wireline logs enabling potential basin-wide correlation.

Comprehensive Compositional and Petrophysical Data: XRF, QXRD, and SEM-EDS analyses were performed on a diverse suite of samples, alongside helium porosity, air permeability, and MICP analyses. These enable calculations of confining capacity in terms of CO2 column height. Results from rock strength testing are also included.

Deliverables: The findings are presented in a fully illustrated physical and electronic report (197 pages). An accompanying Appendix (428 pages) provides a catalogue of sample images, including whole core, petrographic, and SEM-EDS images.

This report is an excellent resource for geoscientists, regulatory bodies, and industry professionals involved in CO2 storage in the Southern North and East Irish seas.
