Diagenetic evolution of the Bunter Sandstone Formation and its controls on reservoir quality: Implications for CO2 injectivity and storage

This paper explores how various geological processes have influenced the properties of the Bunter Sandstone Formation, a potential rock formation for storing CO2 in the UK Southern North Sea. Previous studies noted features that may affect how fluids move through the rock but lacked a clear understanding of how these features form and vary across the region. By analysing rock samples from multiple wells, this study identifies small-scale features that are expected to influence the movement of fluids within the rocks during storage of CO2. Findings highlight how certain layers can act as barriers to fluid flow, while other processes may have led to improved storage potential. The study suggests further research to enhance predictions for safe and effective CO2 storage.
