      abstract     = {The pore space of shales and mudrocks ranges from molecular
                      dimensions to micrometers in length scale. This leads to
                      great variation in spatial characteristics across many
                      orders of magnitude, which poses a challenge for the
                      determination of a representative microscopic pore network
                      for such systems. Standard characterization techniques
                      generally provide volume-averaged properties while
                      high-resolution imaging techniques do not assess a
                      representative range of pore sizes because of limitations in
                      the spatial resolution over the field of view. Due to this
                      complexity, open questions remain regarding the role of the
                      pore network in retention and transport processes, which in
                      turn control oil and gas production. Volume-averaged but
                      spatially resolved information is obtained for pores of size
                      from 2 to 150 nm by applying scanning small- and wide-angle
                      X-ray scattering (SAXS and WAXS) microscopy. Scattering
                      patterns are collected in a scanning microscopy mode, such
                      that microvoxels are sampled sequentially, over a total of 2
                      × 2 mm2 raster area on specifically prepared thin sections
                      with a thickness of 10–30 μm. Spatially resolved
                      variations of porosity, pore-size distribution, orientation,
                      as well as mineralogy are derived simultaneously. Aiming at
                      a full characterization of the shale pore network, the
                      measurements and subsequent matrix porosity analysis are
                      integrated in a multiscale imaging workflow involving
                      FIB-SEM, SEM, and μ-CT analysis.},
