CNOOC Ltd. made a major discovery at the Lingshui 36-1 gas field, an ultra-shallow gas play found in ultra-deep water of the South China Sea.

“South China Sea has been a major region for the company to boost natural gas reserves and production. The successful testing of Lingshui 36-1 further expands the resource base for the development of a trillion-cubic-meters gas region in South China Sea,” Zhou Xinhuai, CEO and president of CNOOC said in a June 6 press release.

The Lingshui 36-1 gas field is located in the western South China Sea, sitting in approximately 1,500 m of water. The main gas-bearing play is the Ledong Formation of Quaternary, with an average burial depth of 210 m. The field has been tested to produce over 10 MMcm/d of open flow natural gas.
