Outline of Final Research Achievements

To evaluate the effect of carbon capture and storage (CCS) technology on methanogenic crude oil degradation in depleted oil reservoirs, we conducted high-temperature and pressure incubation experiments under either in situ and high concentration of CO2 conditions using production water and crude oil collected from three wells in oil reservoirs, Japan. As the result, we observed biological crude oil degradation associated with methanogenesis under in situ oil reservoir condition using an oil reservoir sample. Meanwhile, the high-temperature and pressure incubation under high CO2 concentration showed the decrease of pH due to the increase of CO2 concentration during the incubation. Thus, inhibition effect of methanogenic crude oil degradation was observed in the incubation experiment.
