Optimising a process-based approach for near-surface leakage assessment

Project Summary

Current “baseline” methods in environmental monitoring fall short of what is necessary for successful industrial deployment of geologic CO₂ storage. This project proposes a further application of a process-based approach to environmental assessment. The overall objective is to rigorously assess (and mature) a process-based methodology into a reliable and practical monitoring technology to support the industrial implementation of CCS in hydrocarbon-rich environments. Objectives are:

• update and refine the current process-based geochemical matrix to include various methane inputs;
• demonstrate the capability of Raman technology to provide continuous real-time measurements;
• demonstrate the use of process-based ratios for quantification; and
• choose the measurement technology most appropriate for advancing as best practice in environmental monitoring.
