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

Figure 7

Storage potential per unit area for each prospective area. Due to the large stratigraphic thickness and many reservoir layers, the storage potential per unit area in most depressions in Northwestern Sichuan is quite large, with the largest up to 140 × 10⁴ t/km², at P50 probability level. The storage potential per unit area in Central Sichuan is generally greater than 50 × 10⁴ t/km², at P50 probability level.
