Mesoscale Assessment of CO₂ Storage Potential and Geological Suitability for Target Area Selection in the Sichuan Basin

Figure 6

Candidate prospective areas in the Sichuan Basin. There are eight candidate prospective areas in the Sichuan Basin for deep saline aquifer CO₂ storage which cover more than 5 × 10⁴ km² and mainly locate in Central Sichuan Basin (districts II–V). Only district I is in Northwestern Sichuan. The candidate prospective areas (districts VI–VIII) in Eastern Sichuan are relatively small due to the effects of formation depth, geological safety, and hydrogeological conditions.
