TGS, a leader in energy data and intelligence, has announced the release of the Illinois Basin CO2 Storage Assessment. This detailed study identifies prime reservoirs for carbon dioxide (CO2) sequestration across a 66-million-acre region within the Illinois Basin. With unique data from 2,500 wells and a thorough analysis of key geologic formations, this assessment provides essential insights into reservoir quality, capacity and sealing integrity - factors crucial for advancing carbon capture and storage (CCS) initiatives in this pivotal region.
Leveraging extensive geoscience expertise, TGS offers an integrated evaluation of formation tops and petrophysical characteristics. Comprehensive, actionable insights are then easily accessible within industry-standard workstation environments, empowering energy companies and environmental stakeholders to make informed, data-driven decisions for the success of carbon storage projects.
The Illinois CO2 Storage Assessment provides attribute maps for a whole suite of key reservoir properties and petrophysical curves for thousands of wells across the basin.
Carel Hooijkaas, Executive Vice President at TGS, commented: '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. Our extensive subsurface data expertise and expansive well log library position TGS as a leader in providing the insights needed to drive CO2 storage initiatives forward across the Illinois Basin and beyond.'
This assessment features an all-encompassing stratigraphic framework, meticulous petrophysical analysis and state-of-the-art log curve interpretations. It includes regional mapping of storage properties and volumetric visualizations, offering a thorough evaluation of the area's storage potential. With comprehensive coverage extending across contiguous areas in Illinois, Indiana and Western Kentucky, TGS delivers a vital resource for stakeholders planning and executing carbon storage initiatives with precision and confidence.
Available now, TGS' CO2 Storage Assessment offers unmatched value to the market by reducing uncertainty and enhancing decision-making in the rapidly evolving carbon storage landscape.
