The application of 3D technology for fabrication of artificial porous media samples improves porous media flow studies. The geometrical characteristics of a porous media pore channel: the channel shape, size, porosity, specific surface, expansion ratio, contraction ratio, and the tortuous pathway of...

Using synchrotron-based analytical microprobe techniques, we determine micrometer-scale elemental composition, spatial distribution, and oxidation state of impurities in raw feedstock materials used in the photovoltaic industry. Investigated Si-bearing compounds are pegmatitic quartz, hydrothermal...

CO₂ dissolution is considered as one of the most promising mechanisms for trapping of free-phase CO₂ into brine. It causes an increased density of the brine and initiation of gravitational instability that eventually leads to density-driven natural convection in saline aquifers. Correct estimation...

Alkali-silica reaction (ASR) is a deleterious chemical reaction affecting the durability and service life of concrete structures worldwide. Specifications and recommendations were produced in many countries to ensure that non-reactive aggregates are used in concrete construction or, when reactive...

The paper presents an experimental and numerical investigation on the response of Kuru granite rock under confining compression and static indentation. Triaxial compression tests were executed at different levels of confining pressure. Indirect tensile tests were carried out with Brazilian disks...

Sprayed concrete in combination with rock bolts has successfully been used for permanent rock support in tunnels for decades. The main shortcoming is that sprayed concrete alone is unable to function as permanent waterproofing in tunnels that requires a dry interior tunnel surface. Therefore, the...

This study focuses on developing a robust method for determining contact angles within porous media based on direct geometric determination of local contact angles where we explore two primary approaches: directly measuring the angle at three-phase contact lines and using image recognition/machine...

The effect of barite particle mass fraction and of particle size distribution on the settling and sag potential in oil-based drilling fluid samples is investigated for four fluids with densities of 1.43, 1.55, and 1.60 specific gravity (S.G). The fourth fluid sample, with density 1.60 S.G., had...

SPHINCSS is a new Researcher Project funded by the Research Council of Norway, planned to run in the period 2017-2019. It is a joint project between SPR and NGI, involving Statoil as industry observer. Statoil will provide shale cores to the project and advice on choice of field-relevant scenarios...
