Short Course 5
Short course 5 – 31October
Underground Hydrogen Storage in Rocks: Pore-to-core Scale Flow Processes, X-ray Imaging and Modelling
The course explores techniques for monitoring subsurface CO2 injection, covering rock physics, time-lapse seismic methods, gravity, and electromagnetic techniques. It addresses saturation and pressure effects, early leakage detection, and mapping overburden geology to identify potential weak zones. Discussions include field examples, well integrity issues, and using gas leakage as a proxy for CO2 leakage studies. Laboratory experiments of CO2 flooding, including acoustic measurements, are also featured.

COURSE OBJECTIVE
Upon completion of the course, participants will be able to understand possibilities and challenges related to geophysical monitoring of a CO2 injection process.
Course Outline
- Introduction to underground hydrogen storage (UHS) in porous rocks (30 min)
- Hydrogen economy and significance of UHS in porous rocks
- Comparison with other storage facilities
- Outstanding challenges of UHS in rocks: trapping, dissolution and microbial interactions
- General concepts related to porous media and single-phase flow (1 hr)
- Multiphase flow in porous media and UHS (2 hr)
- Drainage, imbibition, invasion percolation, flow patterns and wettability
- Capillary pressure and relative-permeability curves
- Multiphase flow for UHS in rocks and comparison with other gases
- X-ray imaging of H2 injection and storage in rocks (2 hr)
- Introduction to 3D and 4D X-ray imaging and image processing, and their use in characterising multiphase flow properties
- Recent research on 3D imaging of cyclic injection of H2 in rocks
- Challenges associated with studying microbial interactions and dissolution using X-rays and potential solutions
- Multiscale modelling of multiphase flow processes and its applications in UHS (1 hr)
- Summary and key messages (30 min)
Participant Profile
The course is suitable for individuals with a background in physics, engineering, geology, or geosciences. It is designed for participants ranging from master’s to postdoctoral level, and will also enrich the knowledge base of researchers and technical staff from the industry.
Prerequisites
Basic knowledge of porous media and flow processes is desirable but not required, as these fundamentals will be developed from basic to intermediate levels during the course.
