Comprehensive Evaluation of the Hydrogeological and Water Circulation Systems

Geothermal energy development, carbon dioxide geological storage, and high-level radioactive waste geological disposal projects require an understanding the groundwater behavior in the deep subsurface, which originates from diverse sources, including volcanic hot water, ancient stagnant seawater, and deep fluids from subducted tectonic plates.

In recent years, the depletion of water for irrigation and drinking, due to factors such as drought, has become increasingly apparent, leading to increased use of groundwater from deep confined aquifer. Therefore, to preserve these resources, it is crucial to understand the total amount of underground water, including deep fluids, and the overall water circulation system.

By applying our expertise of geological analysis, which integrates borehole data and various geophysical survey data acquired from petroleum exploration experiences, we contribute to promote sustainable subsurface water use. This is achieved by constructing geological models consisting of deep subsurface structures, physical properties, and fracture systems, and by conducting hydrogeological analyses that includes deep-seated fluids.
