Overview

China (South China Sea). CNOOC-operated. ~10+ bcm/yr combined. Feeds Hainan and mainland via subsea pipeline. Strategic deepwater development zone.

Geopolitical context

China's deepwater gas development in the South China Sea serves both energy and sovereignty objectives — operating rigs and subsea infrastructure reinforces Beijing's territorial claims. CNOOC's ultra-deepwater capabilities have advanced rapidly, reducing dependence on Western drilling technology. The Lingshui fields represent China's ability to develop resources in contested waters unilaterally, a precedent that concerns Vietnam, the Philippines, and Malaysia, all of which have overlapping claims.
