Subsurface Excellence for Large-Scale CCS and Storage

Thursday, 22 October
Room 371 CF
Technical Session
This session focuses on the subsurface challenges and innovations enabling safe, scalable, and economically viable CO2 storage. Topics include site screening and ranking, storage capacity estimation, injectivity management, geomechanics, plume migration, pressure interference, monitoring and verification strategies, and integration with existing E&P assets. Emphasis is placed on lessons learned from pilots and early commercial projects and how subsurface uncertainty is being managed as CCS moves toward industrial scale.
