DOI: 10.3389/feart.2025.1650076
Abstract: Underground gas storage (UGS) facilities are essential for supply security and peak-shaving in natural gas systems, yet their sustainability is limited by an incomplete understanding of water invasion. This study examines the Hutubi UGS, the… read more here.
