Under a scenario where Brent stays below $55 for a prolonged period of greater than 12 months (putting hedging aside) a question to ask is, Who of the Cooper Basin small and mid tier players will survive ?
Now as a shareholder, we don't want to be involved in a company on life support with little growth (presuming Directors act in the best interest of shareholders and not their jobs) the better choice for SH's would be M&A.
So who will survive ??? this likely M&A activity.
I am opening this thread for commentary. My 2 penny's worth are.
STX to be taken out by ORG
SXY to merge with STO on a script basis or ORG
DLS ??? (they have lots of cash so can hold out for better deals)
BPT to move on COE and possibly something more with DLS
It is with some confidence that the low POO willl see the Cooper Basin landscape lot a lot different by YE 2015.
all IMO, and all comments and thoughts welcome.
