Research Outline

Develop a method to continuously monitor CO2 storage reservoir using a portable active seismic source (Portable Active Seismic Source: PASS) and distributed acoustic sensing (Distributed Acoustic Sensing: DAS)

Develop a method to accurately predict the behavior of stored CO2 based on numerical simulations to digitized rock models. Predict long-term CO2 behaviors, such as CO2 mineralization process, and establish schemes to model CO2 behavior under various subsurface conditions.

Estimate earthquake activities around the CO2 storage and geothermal fields. Distinguish artificial earthquakes induced by CO2 storage from natural earthquakes.

Research Methods and Facilities

  • Provide continuous monitoring technology for geological formation in CO₂ storage projects and geothermal power projects.
  • Provide modeling technology for multiphase flow behavior such as CO₂-water within storage reservoir or within membranes. We called the technology as digital rock physical chemistry.
  • Consider a quantitative method to distinguish induced earthquakes from natural earthquakes.
