GEO-SEQ Project

The GEO-SEQ Project has two primary goals: to develop ways to improve predictions of injectivity and capacity of saline formations and depleted gas reservoirs, and to develop and test innovative high-resolution methods for monitoring CO2 in the subsurface.

The Sim-SEQ Project—Understanding Model Uncertainties in Geological Carbon Sequestration

Sim-SEQ was a multi-year U.S. Department of Energy initiative started in 2009 focused on comparing numerical models for GCS—with the objective of understanding and quantifying those uncertainties arising from conceptual model choices. It was a response to past GCS code verification and benchmarking efforts, in that it engaged in model comparison in a broader and comprehensive sense, allowing modelers the choice of interpretation of site characterization data, boundary conditions, rock and fluid properties, among other options.

National Risk Assessment Partnership (NRAP)

The National Risk Assessment Partnership (NRAP) — an initiative within DOE’s Office of Fossil Energy and led by the National Energy Technology Laboratory—applies DOE’s core competency in science-based prediction for engineered–natural systems to the long-term storage of carbon dioxide (CO2).

Potential Impacts of CO2 Leakage on Groundwater Quality

LBNL is one of the main international research organizations addressing concerns about potential impact of deployment of CO2 geological storage on the nation’s groundwater resources. A significant body of our work has targeted the possible groundwater quality changes in response to leakage of CO2 from deep sequestration reservoirs if it were to occur. To better…

Large-Scale Hydrological Impacts of Geological CO2 Storage

If carbon dioxide capture and storage (CCS) technologies are implemented on a large scale, the amounts of CO2 injected and sequestered underground will be extremely large. The figure above shows schematically the large-scale subsurface impacts that will be experienced during and after industrial-scale injection of CO2. While the CO2 plume at depth may be safely…
