Papua LNG is a liquefied natural gas (LNG) production project led by TotalEnergies in response to Papua New Guinea’s desire to develop its gas resources. The gas resources have been estimated at over 1 billion barrels of oil equivalent. The Project will have an LNG export volume of 5.6 million tonnes per year (Mt/y).
Papua LNG project will consist of 9 production wells, 1 water injection well, 1 CO2 reinjection well and a gas processing plant, 320 km of pipeline (out of which 60 km are onshore) from the processing plant to the liquefaction plant, located in Caution Bay, close to Port Moresby.
Papua LNG partners have selected a concept using 4 electrical LNG trains with a cumulative capacity of 4 Mt/y, to be developed within the existing liquefaction plant in Caution Bay, in which it has secured up to 2 Mt/y additional capacity.
The Project opted for 4 innovative electric liquefaction trains of 1Mt/y capacity each, a more modular solution that will reduce the Project’s carbon footprint when combined with renewable energy.
Another special feature is that a system for storing so-called “native” CO2, i.e. CO2 produced with natural gas, was designed to be operational on the first day of operation. The CO2 will be separated and reinjected into one of the two reservoirs to reduce the GHG emissions by circa 1 Mt/y.
By selecting e-trains and re-injecting the native CO2 produced into the reservoirs, Papua LNG confirms its commitment to the reduction of the carbon intensity of the Project.
