“…5 shows the graphical results of the modelling of one of the specimens: (a) the fit between the experimental and simulated curves, (b) the 3D network of pores and throats modelled in the unit cell and (c) the same network representation with solid particles modelled as spheres. Regardless of the real morphology of the particles, the particle size distribution is calculated using the mathematical model proposed by Pospìch and Schneirder (1989).…”

a b s t r a c tVariations in the pore system of sandstones from the so-called Utrillas Formation (Lower Cretaceous, Iberian Peninsula) after CO 2 injection have been investigated in a laboratory on a micro scale. In this study, we present results regarding variations in the pore spaces of sandstones caused by the injection of CO 2 and its permanence in supercritical conditions in contact with a rock sample for two months. The modifications produced in the porosity and pore size distribution have been evaluated on two geological samples, using a 3D modelling of the results obtained by Hg intrusion porosimetry. Reconstructions of the pore structure of the rock before and after CO 2 injection from mercury intrusion-extrusion curves, generating virtual models of pores that reproduce the experimental porosity. By analysing the results, a drastic modification in the mesoporosity of the rock is confirmed, which may have a paramount influence not only on the total storage capacity but also on the percolation of fluid through the rock.
