When CO2 is stored in underground reservoirs, a guarantee is required that it remains underground. Therefore, there is a need to develop an effective monitoring tool that can guarantee safe and effective CO2 storage.
A Danish research project will now solve this problem with artificial intelligence. DTU Offshore will build artificial intelligence into software that automatically and constantly monitors that the CO2 remains underground. The new monitoring solution is being developed in collaboration between DTU Offshore, TotalEnergies and the North Sea Fund under the project name 'Cerberus'. In addition, the Innovation Fund has invested eight million DKK in the project, the foundation announced in a statement.
Based on many years of experience in the processes in the deep layers, the partners in the Cerberus project will develop an AI-based software solution that can both detect potential leaks and identify their cause in real time.
A safe, fast and cost-effective solution
Several existing monitoring technologies, such as conventional 4D seismic surveys, are time-consuming and expensive. Therefore, it is not realistic to use them for systematic monitoring to quickly detect a potential leak. By integrating all available data (and reservoir models), Cerberus will make it possible to define and operate continuous monitoring programs for the reservoirs in a cost-effective manner, thereby guaranteeing the long-term safety of the CO2 storage.
DTU Offshore will combine the research center's knowledge with the experience of experts from TotalEnergies and the Nordsøfonden in the project.
- It is crucial to ensure the precision of the monitoring. The software developed in Cerberus will be validated against field data and high-quality simulations from the reservoirs in the Danish part of the North Sea that are to be reused for CO2 storage, says Hamid Nick, senior researcher at DTU Offshore and technical project manager for Cerberus.
Can play a major role
CO2 storage in the underground is expected to play an important role in combating global warming and in the long term create net-zero emissions of CO2 to the atmosphere.
- Cerberus can potentially contribute to making geological CO2 storage in the Danish reservoirs under the North Sea attractive to operators and, in the longer term, to customers among the CO2 emitters. With a digital solution based on open source software, the Cerberus software has the potential as an application that can be used in Denmark, the North Sea and globally, says Ingelise Schmidt, Subsurface Asset Coordinator CCS at TotalEnergies.
In Greek mythology, Cerberus is the name of the three-headed guardian of the underworld. The Cerberus project will contribute with an AI-based guardian of the stored CO2 with three advantages: Safer, faster and cheaper monitoring.
