Description

Hydrogen behavior in tight rock formations will define the success of many subsurface operations, including geologic hydrogen production and seasonal storage. Understanding the fundamental mechanisms governing transport within these systems necessitates the application of advanced experimental techniques capable of nanoscale observation under dynamic and high-pressure conditions. In the current study, we demonstrate the powerful and unique capability of small-angle neutron scattering (SANS), when combined with pressure cells, to provide insight into hydrogen behavior in shale nanopores. Results shed new light on the links between pore fluid chemistry and hydrogen gas trapping, as well as quantification recovery during pressure cycling.
