Seismic and geophysical data company TGS has released an assessment that identifies prime reservoirs for CO2 sequestration across 66 million acres in the Illinois Basin.

The assessment is intended to help energy companies and environmental stakeholders make informed, data-driven decisions for carbon storage projects.

“The Illinois Basin Carbon Storage Assessment sets a new industry standard with its unmatched data coverage and expert analysis, pinpointing the most effective reservoir and seal formations for CO₂ sequestration,” Carel Hooijkaas, executive vice president at TGS, said in Sept. 3 news release.

The assessment provides insights into reservoir quality, capacity and sealing integrity with data from 2,500 wells and analysis of key geologic formations. It also includes regional mapping of storage properties, volumetric visualizations, an all-encompassing stratigraphic framework, petrophysical analysis and log curve interpretations, TGS said in the news release.

The Illinois Basin covers areas in Illinois, Indiana and Western Kentucky.
