Cnooc reported daily output of natural gas of 587,000 m3. The Baodao 21-1 gas-bearing structure is the first large-scale deep-water natural gas field in the South China Sea, Cnooc said.
“It has achieved the biggest breakthrough in the Songnan-Baodao sag in more than half a century, and will lay a solid foundation for the construction of a trillion-dollar gas region in the South China Sea,” the company added.
