Research data resulting from geoscientific laboratory methods comprise multiple types and formats. A diversity of Earth system science fuels are needed to make research data available to scientists beyond a particular discipline. Global working groups define standards and create tools to improve research data handling in general. Adaption of these solutions to the needs of the geoscientific disciplines is vital to enable the development of a widely applicable geoscientific laboratory database.

In this paper, we evaluate a multi-methodological approach for the comprehensive characterization of reservoir sandstones. The approach enables identification of links between rock permeability and textural and topological rock descriptors quantified at microscale. It is applied to study samples from three sandstone layers of Lower Cretaceous age in northern Israel, which differ in features observed at the outcrop, hand specimen and micro-CT scales, and leads to their accurate characterization.

We studied petrophysical characteristics of three consecutive sandstone layers of the Lower Cretaceous Hatira Formation from Israel. Evaluated micro- and macro-scale petrophysical properties predetermined the permeability of the layers, measured in turn in the lab and upscaled from pore-scale velocities. Two scales of porosity variations were found: at 300 μm scale due to pores size variability, and at 2 mm scale due to high and low porosity occlusions, suggested to control the permeability.

We investigate the pore space of rock samples with respect to different petrophysical parameters using various methods, which provide data on pore size distributions. The resulting cumulative distributions of pore volume as a function of pore size are compared. Considering that the methods differ with regard to their limits of resolution, a multiple-length-scale characterization of the pore space geometry is proposed that is based on a combination of the results from all of these methods.

The OPA material has been intensively studied by a variety of multiple scale and non-destructive 3-D X-ray CT investigations, following a consequent top-down approach to identify specific regions of interest. According to the mechanical experiment, it has been observed that the shear failure is located in a clay-rich area. Within the intersecting area of the two main fractures, a so called mylonitic zone with a particle reduction was observed on the open shear failure using CT and SEM techniques.
