... The unconfined compressive strength (UCS) test is one of the most utilized geotechnical soil analysis techniques for soil stability evaluation. Understanding soil pore size changes during a UCS test is important for estimating soil saturation changes and can help in real-time estimation of soil...

... ABSTRACT Surface relaxivity values were estimated from laboratory nuclear magnetic relaxation diffusion relaxation time (2) maps and used to predict pore-size distributions and permeability. Data were collected on 13 water saturated sandstone and dolostone rock cores. For 9 of the cores...

... was considered from 2D dataset analyzes. Here, we link pore space parameters from 3D images to experimental physical properties of carbonate rocks to improve permeability and velocity predictions. Results show that applying a combination of porosity, pore size and 3D geometrical parameters to permeability...

... conductivity are inversely proportional to formation factor. In a fully water-saturated rock, however, hydraulic conductivity is dominantly controlled by pore size whereas electrical conductivity is only marginally affected by pore size. Consequently, rock types of different pore sizes in a similar porosity...

... in temperature and pressure have the potential to modify the effect of the direct factors on elastic moduli. Carbonate rocks, in contrast to sandstone, display complex pore structures with an astonishing range of pore sizes and pore shapes. Although the pore shape is the most significant rock property, affecting...

... ?. The second parameter Perimeter-over-Area (PoA) captures the overall tortuosity of the pores system. The third parameter, Dominant Poresize, is a measure of the dominant pore size within the thin section. Out of these three parameters, PoA is the most dominant factor controlling velocity at a given porosity...
