From Bubbles to Barrels

The South China Sea E&P reveals how a contested maritime region, rich in hydrocarbons, was systematically transformed through technological grit and strategic partnerships into a pillar of China’s energy security. It begins in the 1950s with the serendipitous discovery of natural gas seeps, or “oil seedlings,” by fishermen in Yinggehai, Hainan, which spurred the first primitive offshore drilling from anchored barges. The narrative details the region’s pioneering, technologically improvised early campaigns in the 1960s and 1970s, leading to milestone discoveries like the Weizhou 10-3 field—China’s first major offshore oil discovery developed through a complex, often contentious partnership with France’s Total. The chapter charts the expansion across key subregions: the Beibu Gulf’s cluster of oilfields, the giant Yacheng 13-1 gas field, and the prolific Pearl River Mouth Basin, where successive discoveries like Huizhou, Xijiang, and the massive Liuhua 11-1 field revealed the basin’s world-class potential. This history is framed by escalating technical ambition—from shallow-water jack-ups to deepwater semi-submersibles—and intricate geopolitics, including cross-strait cooperation and strategic partnerships that transformed the South China Sea from a contested maritime frontier into a proven, vital hydrocarbon province fueling China’s economic ascent.
