The North Sea Transition Authority's announcement of the UK’s second carbon storage licence round underscores the regional potential of the North Sea Basin for the safe and permanent geological storage of CO2. In the Southern North Sea, well-characterised depleted gas fields and deep saline aquifers provide attractive appraisal targets. 

CASP has recently delivered a suite of multi-scale insights into the reservoir and seal intervals of the Bunter Sandstone CO2 Storage Complex, which forms either the primary or secondary storage sites within the Southern North Sea licence blocks. 

Our research comprises seven reports spanning: 

• Novel palynostratigraphy and regional correlation frameworks, enabling more precise subsurface stratigraphic mapping. 
• Cyclostratigraphic insights that improve wireline correlation across the basin. 
• In-depth reservoir composition, sedimentology and diagenesis datasets that inform injectivity, capacity and containment assessments critical to CO₂ storage site screening. CASP 
• High-resolution characterisation of a fully cored Haisborough Group seal analogue section, together with offshore well materials, that help quantify seal capacity. 

These integrated datasets provide valuable technical context to support licence applications, commercial evaluations, and regulatory assurance.
