Oil Search and its joint venture partners, ExxonMobil and Total, have dedicated the last three years to maturing an integrated, three-train brownfield LNG expansion in PNG. The development concept includes the construction of three new LNG trains, with a total capacity of approximately 8 MTPA, and utilising synergies from existing downstream infrastructure located on the PNG LNG plant site.
Extensive studies have confirmed this development concept is the most efficient way of expanding LNG capacity in PNG, delivering significant construction and operating cost savings that will benefit all stakeholders. The expansion trains will be underpinned by gas resources from the Elk-Antelope fields (PRL 15 - Papua LNG) in the Onshore Gulf and the PNG LNG Project and P'nyang fields (PRL 3) in the North-West Highlands.
During 2019, a landmark Gas Agreement was signed for the development of the Papua LNG Project and key commercial terms between the Papua LNG and PNG LNG joint venture partners were largely finalised. Efforts to complete the P'nyang Gas Agreement remain ongoing. Completion of this agreement will enable Front End and Engineering Design (FEED) decisions to be made on the three-train, downstream integrated development.
