... such as spheroids with small aspect ratios have been used to mimic cracks. However, when these pores are dry it has been shown that they all exhibit the same normal-to-shear compliance ratio ( B n / B t ) – regardless of aspect ratio ( α ) – and therefore impact the bulk and shear moduli in a predetermined...

...-rich carbonate mud-rocks. We successfully used digital simulations to predict the elastic moduli of porous organic matter (kerogen) from 10 nanometer resolution FIB-SEM images. This is a unique capability, as it is very difficult to measure the porosity and elastic properties of kerogen in the physical...
