Abstract

The geological storage of carbon dioxide (CO 2 ) is the most suitable option to achieve a large-scale and low-cost CO 2 emissions worldwide, but the selection of favorable areas for the geological storage is the main issue. In this study, evaluation indicators were selected considering four aspects, namely geological conditions, storage potential, hydrogeological conditions, and engineering conditions, based on drilling, geophysical, and geochemical data from the Beibu Gulf Basin. The analytical hierarchy process and the fuzzy comprehensive evaluation method were used to evaluate the suitability of this basin for geological storage of CO 2 . The results suggested that: (1) the Beibu Gulf Basin is suitable for CO 2 geological storage, and the evaluation grade is the highest rating level; (2) considering the techno-economic feasibility, it is necessary to select the target area for CO 2 geological storage with suitable burial depth, superior reservoir conditions, proximity to the CO 2 collection device, and a high degree of exploration.
