- Reservoir quality evaluation of tight carbonate gas reservoirs using fractal–multifractal pore-structure metrics: a case study from the Taiyuan Formation, Ordos Basin, China (2026) · Scientific Reports · doi
The strong heterogeneity and intricate complexity of microscopic pore structures in tight carbonate reservoirs limit productivity. The lack of a quantitative characterization of pore structure heterogeneity hinders the accurate evaluation of reservoir quality. The need for a robust statistical description of pore size distribution without relying on specific geometric assumptions.
