How Do You Keep CO2 Underground?
Learn from Science Rob what makes a good reservoir "seal" and how this enables reliable carbon storage.

How do you keep CO2 underground? We need something to contain it—that's the reservoir rock. Above this reservoir rock consists a layer called "caprock," which acts as a sturdy impermeable seal to prevent fluids, including the injected CO2, from migrating.

Learn from Science Rob what makes a good caprock and how this enables reliable carbon storage. This and other subsurface insights plays a crucial role in evaluating carbon storage sites for appraisal. Learn more about carbon storage evaluation measurements and how they are an early, critical step in any carbon sequestration project.
