Abstract
Deep-saline aquifers could be instrumental in the geological storage of carbon dioxide due to their relatively good reservoir properties, high volume, and prevalence. However, there are a few difficulties which should be overcome to obtain effective stores in such reservoirs. Most problems are related to formation damage caused by salt precipitation. Due to the complexity of such systems, it is necessary to identify crucial processes, phenomena, factors, and products. In our work, we present a novel platform to trace precipitation ‘in situ’ using microfluidics and Raman spectroscopy. We have built a set in which we can investigate not only the salt deposition phenomenon in pores or microchannels by visual observation but also, because of Raman spectroscopy, determine the kinetics of reactions, carbon dioxide solubility, phase composition, and crystal composition. On the basis of our research, we have identified intensive clogging of pores and fast growth of crystals on the rock-like grain boundaries and bottlenecks. Furthermore, in a 20% weight NaCl solution we have found precipitated carbonates, for example, nitrate. Our results can broaden our understanding of CCS in high-saline aquifers and contribute to the development and common use of this process.
