It depends on how long oil price will stay around the US$30/bbl or lower. There are only 5 US shale companies that can produce below $30/bbl that means the other 100+ producers are stuffed if this low oil price continues. Firstly you will see non-completions of drilled wells then you will see number of rigs drop off after a while you may see existing oil wells plugged, which damages the well.. So Shale oil services companies will be impacted then you start see drop in US oil gas production as you need new completions to maintain production.. This is why trump is already talking about bail out package for US Shale Oil gas industry.

We have witnessed gas shortage in Australia ie. DWGM reached $10/gj, but recently we seen it drop around $4-5/gj..

You probably better off looking at this

in my opinion EEG is more play on how where you see the Australian domestic gas price in the future.

I believe all the advance project on import terminals have been canned by the majors.. they are really looking at beetaloo basin to bridge the gap.. I have heard they are landing at $7/gj as long term average,is this a high enough price to develop NT pipeline at the beetaloo basin....this will depend on number factors how productive are the wells. Government policy to encourage the use of natural gas...
