Application of low field and solid-state NMR spectroscopy to study the liquid/liquid interface in porous space of clay minerals and shalesBorysenko, Artem, Clennell, Ben, Burgar, Iko, Dewhurst, David, Sedev, Rossen, Ralston, John 15 December 2015 (has links) (PDF)
In petroleum research understanding displacement, redistribution, and adsorption of oil and water plays an important role. To study complex multi-component systems such as liquid/liquid/mineral interactions in the porous space of clays and shales we applied low
field (2 – 15 MHz) and high resolution (300 MHz) NMR spectroscopy. The detailed NMR analysis shows that the results from low field NMR measurements are in good correlation with the solid-state data. Consequently the process of liquid/liquid displacement can be characterised by considering the relaxation times, signal amplitudes and chemical shifts together.
