Abstract

CO₂ geo-storage efficiency is strongly influenced by the wettability of the CO₂-brine-mineral system. With decreasing water-wetness, both, structural and residual trapping capacities are substantially reduced. This constitutes a serious limitation for CO₂ storage particularly in oil-wet formations (which are CO₂-wet). To overcome this, we treated CO₂-wet calcite surfaces with nanofluids (nanoparticles dispersed in base fluid) and found that the systems turned strongly water-wet state, indicating a significant wettability alteration and thus a drastic improvement in storage potential. We thus conclude that CO₂ storage capacity can be significantly enhanced by nanofluid priming.
