A 100 mmcfd shortfall between gas supply and demand in the Australian east coast market will emerge through 2017. Fingers have been pointed at the CSG LNG projects which have led to total demand rising threefold to 5 bcfd. But reduced development and exploration spend due to capital constraints and opposition from governments and communities have also contributed. Increased production from already onstream developments including the CSG LNG projects should fill most of the deficit out to 2021. But the shortfall will only get worse and by 2025 it could rise to around 500 mmcfd. What are the next steps to resolve the impending shortfall?
