The midstream segment produces refined petroleum products at Napa Napa in Port Moresby, Papua New Guinea for the domestic market and for export. It is developing liquefaction and associated facilities in Papua New Guinea for the export of liquefied natural gas (LNG). The downstream segment markets and distributes refined products.
