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.},
