Preliminary Environmental Risk Assessment Study Using US DOE’s National Risk Assessment Partnership on Leakage through Legacy Wells at the Shenhua CCS Demonstration Project

Key Findings: • Demonstration Project in the Ordos Basin, China to provide an improved explanation for the pressure and injectivity at the site. • Developed models to provide a range of scenarios with the target 300k tons of CO2 being successfully injected into 5 saline aquifers layers, with the sandstone Liujiagou formation receiving most of the injection. • Risk assessment based on these scenarios honoring historical injection data suggests that there is a low probability of CO2/brine leakage through legacy wellbores in the area, including the injection and two monitoring wells.
