Why is this research needed?

Our research aims to make CO2 storage safer by studying how faults in underground storage sites behave during CO2 injection. By using advanced geophysical methods and subsurface models, we will track stress changes to prevent fault reactivation, especially earthquake hazards, and ensure CO2 stays securely stored. This project will help reduce environmental risks and support global efforts to lower carbon emissions. We will share our findings widely to inform policymakers, industry professionals, and the public, promoting the safe and effective use of CO2 storage technology.

What is this research investigating?

1 – Develop comprehensive methodologies to ensure long-term CO2 containment in faulted storage sites
2 – Investigate fault behaviour during CO2 injection, focusing on the reservoir, caprock and overburden layers
3 – Enhance numerical simulations and risk assessments to understand and mitigate fault reactivation risks
4 – Integrate 4D seismic data with geomechanical models for accurate monitoring and evaluation
5 – Facilitate effective communication of fault risks and project findings to stakeholders, policymakers and the industry
6 – Disseminate research outcomes through publications, conferences and digital platforms to improve CCS technology and public acceptance

What does the research hope to achieve?

Academic beneficiaries of this research include geoscientists and engineers specializing in carbon capture and storage (CCS), who will gain advanced knowledge on fault behaviour during CO2 injection. Researchers in geophysics and geo-mechanics will benefit from new methodologies integrating 4D seismic data with subsurface modelling. Environmental scientists will gain insights into reducing the environmental risks associated with CO2 storage. Additionally, this research will enhance interdisciplinary collaboration and provide a rich resource for academic publications and teaching materials, advancing the overall field of CCS technology. Ultimately, the public will benefit from ensuring CCS is safe, supporting global efforts to mitigate climate change.
