How does CO2 behave below the Earth's surface? When CO2 is injected underground during carbon storage, saline rock reservoirs—those housing salty water also referred to as "brine"—are prime candidates. The interaction between the rock, CO2, and brine is unique from project to project. So understanding the  composition of each is crucial for derisking operations.

Learn from Science Rob about the rock-brine-CO2 interaction and how it impacts 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.
