CCUS (Carbon Capture, Utilisation and Storage)

What is CCUS?

Carbon Capture, Utilisation, and Storage (CCUS) is the use of technology and processes to remove CO2 from the atmosphere, followed by recycling the CO2 for utilisation (by conversion into, plastics, concrete, biofuel, etc) and finally any excess CO2 permanently being stored underground. 

CCUS plays an important and diverse role in meeting global energy and climate goals but despite the adoption of alternative energy sources and energy efficient systems to reduce the rate of CO2 emissions, the cumulative amount of CO2 in the atmosphere needs to be reduced to limit the detrimental impacts of climate change (IPCC, 2013).

CCS (Carbon, capture and storage) is the process of storing carbon captured in the subsurface, without the utilisation.

How does it work?

The capture of CO2 can be done in different ways, directly from the sources of emissions or even in the air. This process can involve a variety of technologies, such as the use of solvents or membranes.

Once captured, the concentrated CO2 becomes capable of being transported to environments where it can be used as raw material for the development of new products, such as synthetic fuels. An alternative option is to store it underground.

The idea of ​​storage seems, at first glance, the best solution to decrease the levels of carbon dioxide in the atmosphere, especially because the potential of the storage reservoir is quite vast. In addition, the technology involved is already mature. However, the process involves important legal issues, for example, liability for the risk of possible leakages and jurisdictional complexities in relation to the use of underground property (IEA, 2022; NETL, 2022).

How can seismic accelerate CCUS?

CO2 storage requires certain geological conditions to be met to make it successful. This in turn requires a thorough understanding of the subsurface, not only to find the right host, but to also monitor the newly created “reservoir” because CO2 leakage can incur serious risk if it reaches certain geological formations.

Utilising seismic for CCUS applications can:

  • Significantly improve knowledge of the subsurface, giving more confidence to project investment
  • Help assure projects are sanctioned by supporting the permitting process; Property and Mineral Rights, HSE, Permanence, Resource Management
  • De-risk “pre-drill” decision-making during the exploration phase
  • Effectively monitor the subsurface during injection and post-injection to avoid loss of integrity
  • Improve the overall safety, compliance, and efficiency of CCUS operations
  • Help companies adhere to in-country regulations, such as “US UIC Class VI Rule”
  • Help to secure tax incentives, such as “IRS 45Q” in the US

Regulation

Long permitting periods, with legislation that is not clear on what exactly has to be done (seismic or not)

How seismic can be used in CCUS applications?

During exploration:

  • Scouting (2D and pseudo-3D surveys) - regional scouting to identify and grade potential sites for CCUS projects
  • High-density 3D surveys - for baseline/pre-drill, monitoring/repeat baseline, allowing companies to achieve a “gold standard” for permitting and regulation compliance
  • A 3D seismic survey is not a mandatory requirement that is prescribed in regulations but is best practice for accessing a clear image of the subsurface
  • Demonstrate to the regulator and key stakeholders that the storage of CO2 in the subsurface is safe and the seal, reservoir, and overburden are not compromised
High density

During operations (monitoring)

  • Assure a long-term monitoring plan is in place to reduce risk, operate safely and in line with the project objectives
  • Provide evidence to the regulators demonstrating your commitment to safety integrity assurance
  • Obtain the most accurate large-scale method (seismic) to track the CO2 plume in the subsurface
  • Comply with seismicity monitoring requirements in specific regions and environments that mandate this
