Research activities have focused on 1) the development of in-situ CO₂ monitoring technology with laboratory experiments as well as a small-scale test bed, 2) estimations of potential CO₂ storage capacities for saline formations in the continental shelf area, 3) density-driven convection in a fractured porous media, and 4) development of DVS (Distributed Vibration Sensing) technologies as a cost-effective alternative of 4D seismic and microseismic monitoring for the assurance and safety of large-scale CO₂ geological storage. Recent results are summarized below.
✓ Basin-scale estimation of CO₂ storage capacities of deep saline formations in West Sea and of sub-basalt formations in South Sea (Fig. 1)
✓ Lab and field experimental study to develop a DVS system and directional vibration sensing techniques (Fig. 2)
✓ Investigation of impacts of single and multiple fractures on transport of dissolved CO₂ plumes in various geological settings (Fig. 3)
