Eighty percent of the world’s energy relies on fossil fuels and under increasingly stricter national and international regulations on greenhouse gas emissions, storage of CO₂ in geologic repositories is a feasible and vital solution for near- and mid-term reduction of carbon emissions in any climate change mitigation strategy. To achieve the 2°C climate goal set by the Paris Agreement, projections by the International Energy Agency indicate that around 4,000 million tons of CO₂ per year would need to be captured and stored by 2040, growing to around 6,000 million tons per year by 2050. Currently, ~20 large-scale carbon capture and sequestration (CCS) projects are operational around the world with ~30 billion USD investment in comparison to more than 2 trillion USD spent on renewable energy. Therefore, a significant opportunity exists for CCS nationally and globally. The Southeast Offshore Storage Resource Assessment (SOSRA) and the Southeast Regional CO₂ Utilization and Storage Acceleration Partnership (SECARB-USA) research projects were funded by the U.S. Department of Energy with the Southern States Energy Board (SSEB) in the lead. This talk is focused on the development of (1) offshore prospective storage resource assessment of the Upper and Lower Cretaceous as well as Upper Jurassic sections within the Southeast Georgia Embayment (SGE) and (2) onshore potential reservoirs in the Cleveland and Skinner formations of the Anadarko Basin, Oklahoma. This work includes a replicable workflow of model-based inversion that provides the tools to discriminate lithology and predict porosity and permeability necessary for CCS. These analyses have included integration of seismic surveys with core samples and geophysical well logs leading to a detailed stratigraphic, structural, petrophysical, and injection simulation model showing the heterogeneity and highly complex tectonic evolution of the target reservoirs of the Eastern North American Margin and the Anadarko Basin.
