The West Sichuan Gas Field project has total reserves of 100bcm of natural gas, the Chinese state oil and gas major said, adding that the field is also expected to produce 130,000 metric tons of sulfur per year.

The project is Sinopec's third gas field in the Sichuan Basin with more than 100bcm in reserves.

Sinopec currently has proven natural gas reserves of nearly 3 trillion cubic metres in the Sichuan Basin, with an annual output of 26bcm, the statement said.
