GEOLOGICAL INVESTIGATION OF CO2 STORAGE AND INNOVATIVE RESEARCH FOR CO2 MONITORING TECHNOLOGY
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) CO2 -water-rock interaction experiments and two-phase (CO2 and brine) flow visualization under various reservoir conditions, and 4) distributed acoustic sensing (DAS) development using fiber-optic cable for measurements of CO2 behaviors in subsurface environments. Recent results are summarized below.
