Exxon Mobil Corporatio says it has shipped the first cargo of liquefied natural gas (LNG) from the $19 billion PNG (Papua New Guinea) LNG project ahead of schedule. PNG LNG, operated by ExxonMobil affiliate ExxonMobil PNG Limited, is expected to produce more than 9 trillion cubic feet of gas over its estimated 30 years of operations. The first cargo is bound for LNG customer Tokyo Electric Power Co. Inc. (TEPCO) in Japan. Production from the first train started in April, 2014, and production from the second train has also started as additional wells came online. Construction of PNG LNG began in 2010, and took more than 190 million work hours to complete. At its peak, the project employed more than 21,000 people.
