In an email yesterday, the company’s spokeswoman said production was happening according to design and followed a safe ramp up process over the last few months.
The project was expected to produce more than nine trillion cubic feet of gas over its estimated 30 years of operations.
It began its first LNG shipment in May to Japan.
The development has long-term contracts with Tokyo Electric Power Co., CPC Corp. of Taiwan, Osaka Gas Co. and China Petroleum & Chemical Corp.
ExxonMobil said it has used six ships to transport 12 LNG cargoes to customers which were sold on the spot market to customers in Asia.
Its partners, including Oil Search Ltd and Santos Ltd, are targeting an increase in Asian demand for natural gas. The companies are considering an expansion of the development.
