Chemical Tracer Review for CO2 Leak Monitoring at QICS Site

UKCCSRC Call 1 project report from the British Geological Survey reviews chemical tracers for carbon capture and storage monitoring. The report analyzes tracer applications, costs, and environmental impacts for a controlled CO2 release experiment offshore Scotland during 2012. It aims to identify suitable tracers for detecting and quantifying CO2 leakage from subsurface storage.

Use Cases

• Compare costs, availability, and environmental impact metrics for different chemical tracers to select optimal monitoring agents.
• Assess tracer detection limits in the context of CO2 passing through water-saturated seabed sediment and into the water column.
• Analyze legal considerations for tracer deployment in the United Kingdom to inform regulatory compliance for CCS projects.
• Evaluate injection methods and required sampling strategies for tracers at the QICS experimental facility.

Strengths

• Report details a controlled release of 4.2 tonnes of CO2 during spring/summer 2012 at the QICS site.
• Analysis is grounded in a specific offshore experiment located approximately 350 meters offshore Oban, Scotland, at 10 meters water depth.
• Provides a structured review covering tracer applications, cost analysis, legal frameworks, and identified knowledge gaps.

Limitations

• The report is superseded by a later scientific paper, indicating its findings may not represent the current state of research.
• Data is presented as a textual report; no structured tabular data, sample data, or quantified results are provided for direct analysis.
• Scope is limited to the specific conditions of the QICS experiment, which may not generalize to all CCS monitoring scenarios.
