Papua LNG

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.

Papua LNG project started with a significant gas discovery located within the Gulf Province, the Elk-Antelope field.

Elk was discovered in 2006 by Elk-1 and Antelope was discovered in 2007 by Elk-4.

The field lies south of the Bismarck range mountains and is approximately 120 km inland from the township of Kerema and 360 km northwest from Port Moresby, the capital city and major industrial center, and is now referred as the PRL15.



The upstream facilities are situated in a hilly area, between 50 and 400 meters above sea level, covered in dense jungle, with many rivers including one of the main accesses, the Purari River.  

The coastal approach tends towards mangrove swamps.

The region is sparsely populated with little infrastructure.

As per now, the production of about 1 billion barrels of oil equivalent is planned. The gas will supply 4 electric liquefaction trains with a combined capacity of 5.6 million tonnes per annum (Mtpa).

Papua LNG will include 9 production wells and a gas processing plant, a 320km pipeline, 260km of which will be offshore, as well as liquefaction units in Port Moresby.



PRL 15 Venture 

The Project is operated by TotalEnergies – the world’s second largest LNG player- which is committed to responsibly meet the world’s increasing demand for sustainable, reliable, and cleaner energy sources.

The Papua LNG project covers the Upstream part of the overall development and the Downstream part (the 4 electric liquefaction trains) which will be integrated in the existing PNG LNG plant. 


Development Scheme

The development and monetization of the gas resources involves the construction of major infrastructure such as a main pipeline to bring the gas from PRL 15 location in Gulf Province to a liquefaction plant installed on the coast of the Gulf of Papua, at Caution Bay near Port Moresby.

In the coming months, the construction of the LNG facilities will provide opportunities for professional training, employment, and contracts for the supply of goods and services.

The construction phase also manages environmental and social aspects to reduce risks and mitigate the impacts of a project of that scale.


Project Drivers

The overall performance for a successful achievement of the Project will be defined in order to comply with the highest HSE standards, including its footprint optimization, the National Content expectations, the economic and social context, as well as other specific objectives that should correspond to precise, measurable and attainable targets.

The Papua LNG project is committed to collaborating with the PNG communities and government officials to safely develop these resources in a manner that protects the environment, encourage additional foreign investment, and contributes to the long-term social and economic stability of the country. 


A Project of the scale of Papua LNG could not be successful without the collaboration of its co-venturers.

Experience, ideas and resources are helping to build and operate a large-scale project and contribute to the growth and development of Papua New Guinea.

Kumul Petroleum Holdings Limited (KPHL) is Papua New Guinea’s national oil and gas company (NOC).

The NOC was created by an Act of Parliament through the Kumul Petroleum Holdings Limited Authorization Act 2015.

Through Kumul Petroleum Authorization Act 2015, KPHL is mandated to protect and maximize the value of the Country’s petroleum assets so that it can contribute to the maximum wealth for the people of Papua New Guinea.

Consistent with its vision, KPHL will continue to create value and opportunity for PNG and its people by becoming a major national oil and gas corporation. This means "creating wealth and opportunities for Papua New Guinea now and into the future.
