Ben Callow is a postgraduate research student at the University of Southampton, within Ocean and Earth Science, National Oceanography Centre Southampton.
 
Ben’s PhD thesis looks to characterise the permeability and structure of onshore and offshore chimney structures in order to quantify and assess the risk of CO2 leakage from storage sites underlying these structures.

The key aim of the project is to quantify the permeability and fully understand the dynamics and mechanisms of fluid flow through chimney structures, fracture networks and unconsolidated sediment. The work will contribute to WP3-Leakage Pathways through the overburden.
