      abstract     = {This paper presents a detailed description and evaluation
                      of a multi-methodological petrophysical approach for the
                      comprehensive multi-scale characterization of reservoir
                      sandstones. The suggested methodology enables the
                      identification of links between Darcy-scale permeability and
                      an extensive set of geometrical, textural and topological
                      rock descriptors quantified at the pore scale. This approach
                      is applied to the study of samples from three consecutive
                      sandstone layers of Lower Cretaceous age in northern Israel.
                      These layers differ in features observed at the outcrop,
                      hand specimen, petrographic microscope and micro-CT scales.
                      Specifically, laboratory porosity and permeability
                      measurements of several centimetre-sized samples show low
                      variability in the quartz arenite (top and bottom) layers
                      but high variability in the quartz wacke (middle) layer. The
                      magnitudes of this variability are also confirmed by
                      representative volume sizes and by anisotropy evaluations
                      conducted on micro-CT-imaged 3-D pore geometries. Two scales
                      of directional porosity variability are revealed in quartz
                      arenite sandstone of the top layer: the pore size scale of
                      ∼0.1 mm in all directions and ∼3.5 mm scale related
                      to the occurrence of high- and low-porosity horizontal bands
                      occluded by Fe oxide cementation. This millimetre-scale
                      variability controls the laboratory-measured macroscopic
                      rock permeability. More heterogeneous pore structures were
                      revealed in the quartz wacke sandstone of the intermediate
                      layer, which shows high inverse correlation between porosity
                      and clay matrix in the vertical direction attributed to
                      depositional processes and comprises an internal spatial
                      irregularity. Quartz arenite sandstone of the bottom layer
                      is homogenous and isotropic in the investigated domain,
                      revealing porosity variability at a ∼0.1 mm scale, which
                      is associated with the average pore size. Good agreement
                      between the permeability upscaled from the pore-scale
                      modelling and the estimates based on laboratory measurements
                      is shown for the quartz arenite layers. The proposed
                      multi-methodological approach leads to an accurate
                      petrophysical characterization of reservoir sandstones with
                      broad ranges of textural, topological and mineralogical
                      characteristics and is particularly applicable for
                      describing anisotropy and heterogeneity of sandstones on
                      various rock scales. The results of this study also
                      contribute to the geological interpretation of the studied
                      stratigraphic units.},
