Carbon Dioxide Storage Potential in the North Sea

The feasibility of carbon dioxide (CO2) injection into an extensive aquifer in the North Sea is assessed. The impact of seal<br>permeability, horizontal permeability, perforation interval, number of wells, aquifer size and cap rock size on the effectiveness<br>of large-scale storage is assessed. A compositional numerical simulation is performed in the period of 50 years (30 years of<br>injection and 20 years post-injection). We study volumes equivalent to the emissions of a large power station in the UK, 10<br>Mtonnes/year and find the necessary aquifer dimensions, cap rock size and horizontal permeability to allow safe storage<br>assuming that the pressure increases by no more than 10%.
