South China Sea Energy Exploration and Development
The U.S. Energy Information Agency estimates that the South China Sea holds about 190 trillion cubic feet of natural gas and 11 billion barrels of oil in proved and probable reserves, most of which lie along the margins of the South China Sea rather than under disputed islets and reefs. The U.S. Geological Survey in 2012 estimated that there could be another 160 trillion cubic feet of natural gas and 12 billion barrels of oil undiscovered in the South China Sea. Beijing’s estimates for hydrocarbon resources under the sea are considerably higher but still modest in relation to China’s overall demand—the country’s oil consumption in 2018 is expected to top 12.8 million barrels per day.
