Borehole Monitoring Technologies for CO2 Storage Containment Verification

Abstract

Summary Carbon capture and storage (CCS) is a key climate mitigation technology required to meet the Paris Agreement goal for limiting global warming. At Shell, we demonstrate that a CO2 storage site is performing as expected using a comprehensive risk-based Measurement, Monitoring and Verification (MMV) framework. Quest is the first Shell CCS project to have implemented a MMV plan for CO2 storage performance verification. We report here some of the operational data and insights from the borehole geophysics technologies deployed at Quest. The data acquired using the injection and monitoring wells have been critical in demonstrating containment and conformance within the geosphere of this CO2 storage site.
