The latest monitoring progress for Shenhua CO2 storage project in China

Shenhua Ordos CCS project is the first full-ranged demonstration project including CO2 capture, transportation and storage in China. In order to ensure the safety of CO2 storage in the saline aquifers, the monitoring scheme was designed and detailed monitoring data was obtained. The whole monitoring schemes include under-ground, ground and above-ground monitoring at the pre-determined monitoring heights. Vertical Seismic Profile (VSP) monitoring results of three times indicate that the migration of the injected CO2 stays within 450 m around the injection well. No CO2 vertically leaked to the surface. Other monitoring results did not show any leakage from the saline aquifer, which further proves the safety of CO2 storage in the saline aquifers. Continuous monitoring is required to further track the CO2 movement and to ensure the safety of CO2 saline storage over time.
