Quantitative Evaluation of CO<sub>2</sub> Storage Potential in the Offshore Atlantic Lower Cretaceous Strata, Southeastern United States
The geological storage of CO<sub>2</sub> in the Earth’s subsurface has the potential to significantly offset greenhouse gas emissions for safe, economical, and acceptable public use. Due to legal advantages and vast resource capacity, offshore CO<sub>2</sub> storage provides...

| description | The geological storage of CO<sub>2</sub> in the Earth’s subsurface has the potential to significantly offset greenhouse gas emissions for safe, economical, and acceptable public use. Due to legal advantages and vast resource capacity, offshore CO<sub>2</sub> storage provides an attractive alternative to onshore options. Although offshore Lower Cretaceous reservoirs have a vast expected storage capacity, there is a limited quantitative assessment of the offshore storage resource in the southeastern United States. This work is part of the Southeast Offshore Storage Resource Assessment (SOSRA) project, which presents a high-quality potential geological repository for CO<sub>2</sub> in the Mid- and South Atlantic Planning Areas. This is the first comprehensive investigation and quantitative assessment of CO<sub>2</sub> storage potential for the Lower Cretaceous section of the outer continental shelf that includes the Southeast Georgia Embayment and most of the Blake Plateau. An interpretation of 200,000 km of legacy industrial 2D seismic reflection profiles and geophysical well logs (i.e., TRANSCO 1005-1-1, COST GE-1, and EXXON 564-1) were utilized to create structure and thickness maps for the potential reservoirs and seals. We identified and assessed three target reservoirs isolated by seals based on their effective porosity values. The CO<sub>2</sub> storage capacity of these reservoirs was theoretically calculated using the DOE-NETL equation for saline formations. The prospective storage resources are estimated between 450 and 4700 Mt of CO<sub>2</sub>, with an offshore geological efficiency factor of dolomite between 2% and 3.6% at the formation scale. |
