FEI has announced a solution for 3D, nanometer-scale characterization of pore networks. The Helios Nanolab Dualbeam system images kerogen, porosity and microstructures in three dimensions (3D) with nanometer-scale resolution. The data are essential to determining the production potential of unconventional gas reservoirs, optimizing extraction procedures and designing simulators of the nanoscale pore structure. The Helios system captures images and develops a 3D microstructural model of the pore structure, including the subvolumes of kerogen and its connectivity.
