Probing the Behaviour of Fluids Confined in Porous Materials by Neutron Scattering: Applications to CO Sequestration and Enhanced Oil and Gas Recovery.

The current review presents a discussion on the utility of neutron scattering, with emphasis on neutron total scattering and small-angle neutron scattering (SANS), to explore the structural properties and the phase behaviour of fluids confined in nanopores. The effectiveness of contrast matching SANS on the evaluation of accessibility of porous materials to invading fluids is highlighted too. This review provides also an overview regarding the neutron scattering studies on the structure and the accessibility of greenhouse gases in the complex pore network of geomaterials, with applications to CO geological sequestration and enhanced oil and gas recovery.
