In a report on PNG LNG partner Oil Search, Macquarie Wealth Management said debottlenecking remained a priority at the Papua New Guinean LNG operation.
The broker said 10-15% of additional capacity could be unlocked.
"The recent production improvements have required little incremental capital expenditure and seemingly relate to higher utilisation of plant," the broker said.
