A final decision on a long-delayed $20 billion gas project in Papua New Guinea will be made by the end of the year, one of the companies involved in the massive venture says.

Oil and gas group Santos has partnered with multinational energy giants TotalEnergies and ExxonMobil on the Papua LNG project to develop two onshore gas fields, 360km northwest of the capital Port Moresby.
