This is an increase on the $12.5 billion pre front end engineering and design (FEED) estimate due principally to the inclusion of pre start-up operating costs and scope changes including acceleration of some works from later phases of the project.

The partners in the PNG LNG project include: ExxonMobil, Oil Search Limited, Santos, AGL Energy Limited, Nippon Oil Corporation, MRDC (a PNG company representing landowner interests) and Eda Oil.
