HOUSTON, Texas (12 August 2024) - TGS, a leader in energy data and intelligence, is pleased to announce 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.
