| Outline of Final Research Achievements |
This study focused on the development of the well cement which has a high resistance to harmful gas leakage in Carbon dioxide Captured and Storage (CCS) and Steam Assisted Gravity Drainage (SAGD) projects; CCS is a technology to reduce CO2 emission from power plant and factory by injecting CO2 into a couple of 1000m deep ground and SAGD is a heavy oil recovery technology to reduce heavy oil viscosity by the injection of hot steam and extract it from underground. As a result, it is experimentally found that the addition of fly ash and silica fume in oil well cement can be effective for the inhibition of mechanical deterioration and gas leakage. It is also suggested that the polymer may inhibit the chemical deterioration due to the CO2 in CCS project.
