China Successfully Tests Gas Hydrate in South China Sea

China has successfully tested for natural gas hydrates in Shenhu area of South China Sea, China Geological Survey said May 18. The gas flowed continuously for eight days with average production of 16,000 m³/d with highest output in one day at 35,000 m³. Almost all the gas extracted is methane.

Gas hydrates are crystalline form of methane and water, and exist in shallow sediments of outer continental margins. They are envisaged as a viable major energy resource for future.

Recently, Japan confirmed that gas had been produced from methane hydrate during the country's second ever test. Japan Oil, Gas and Metals National Corporation (Jogmec) May 4 said gas has been flared from its second test to extract gas from methane hydrates offshore Atsumi and Shima peninsulas.
