Guest Speaker(s): Hadi Nourollah (CO2CRC)

Dr. Hadi Nourollah is a Senior Geophysicist with 20 years of international experience in Petroleum and CCS industries. Hadi received his Master’s degree in Petroleum Geosciences at Imperial College, London and completed his PhD in Geophysics at Curtin University. He has worked for National Oil Companies in the Middle East, operators in SE Asia and directed an international consultancy in Australia for a decade prior to joining the global CCS leader CO2CRC. Hadi has experience in seismic data acquisition, processing and static modelling of geological data in Australasia, South America and the Middle East. His research interests are the sealing potential of shales and innovative seismic techniques such as Fibre Optics.

CCS Monitoring and Verification: Why and How?

Presented by Hadi Nourollah (CO2CRC)


Monitoring and verification of CO2 plume is essential in understanding the effectiveness and potential risks associated with carbon capture and storage (CCS). Despite some degrees of ambiguity in the regulations for the monitoring requirements, all regulators require that the operator to monitor the injection, migration and stabilisation of the plume. 20+ years of post-injection monitoring itself can be a costly task which requires careful planning.

The essence of monitoring lies in the continuous assessment of the behaviour and movement of the CO2 plume within the geological storage site. This includes measurements of pressure, temperature, and saturation (or their changes) of the underground reservoir where the CO2 is stored. By monitoring these parameters, the operator can ensure that the stored CO2 is being contained as intended and is not leaking into the atmosphere or triggering any unwanted effects such as seismic activity.

Verification, on the other hand, focuses on confirming the accurate placement and containment of the CO2 within the storage site. This involves the use of various monitoring techniques, such as seismic surveys, well logging, and pressure testing, to assess the integrity of the storage reservoir and detect any potential leaks or migration pathways. Verification is crucial in ensuring the long-term safety and reliability of CCS projects.

Monitoring plans are very site specific, but the learnings can be carried over to other projects. This talk aims to introduce some elements of risking that are to be considered for any monitoring plan and how they may be addressed.
