- Total estimated reserves: approximately 1,800 trillion cubic feet (tcf) — the largest single gas reservoir globally
- Iran's South Pars contributes approximately 70–80% of Iran's total gas production
- Qatar's North Dome makes Qatar the world's second-largest LNG exporter (after the US); Qatar supplies ~25% of global LNG
- Ras Laffan Industrial City (Qatar) is the world's largest LNG production and export complex
- Iran's South Pars has 24 development phases, most now in production
