CO2 and gas/energy storage

Work Package 2

CO2 and gas/energy storage

Vision

This WP will advance methods for geophysical monitoring and forecasting of CO2 storage projects, as part of global decarbonisation efforts, generating novel scientific insights and stimulating new innovations.

What we will do

We will look at the accuracy and effectiveness of CO2 storage monitoring methods using existing projects (like Sleipner) and emerging sites (like the Northern Lights).  Using scaled laboratory experiments, high-resolution earth models and seismic imaging datasets we will work out:

  • How accurately can we detect the 'cloud' of CO2 in the subsurface?
  • Better ways to predict fluid flow and ground deformation around injection sites
  • The behaviour of hydrogen and methane in seasonal energy storage systems.

Projects

Projects

  • Improved detection of leading edge up-dip and down-dip lateral migration of CO2 plumes using coupled plume-dynamics models and 4D seismic processing (PhD)

  • Improved geophysical detection and forecasting of vertical migration and leakage of CO2 into realistic high-resolution models of overburden sequences (PhD)

  • Acoustic detection experiments in scaled laboratory models in CO2-lab facility
