Meanwhile, three Gulf province parliamentarians have recently made a joint statement criticising the lack of progress on InterOil's discoveries in the region.

ExxonMobil remains in exclusive negotiations over acquiring at least a 4.6 trillion cubic feet of natural gas slice of InterOil's Elk-Antelope discoveries to underpin a third train expansion of the PNG LNG.
While this approach involves piping a large portion of the Elk-Antelope gas out of the province to PNG LNG infrastructure, it is unclear how much influence the Gulf parliamentarians will have over such a project of national significance.
