I think its....
just another oil patch to them, they have many just like it around the world. The Nigeria unrest bothers them,and the politics are troubling.
I believe their thinking is, if the can't buy controlling interest in it...then they don't want it!...and they don't really want to pay a fair price for it either.
They have been getting rights off W.Africa for years, for pennies on the dollar, and they are stuck in that mindset,..imo.
Big Oil has never really had any real competition for deepwater rights before...this China thing is new to them....and who the he11 is this damn ADDAX company, anyway.
Big Oil is in a transition period,imo.
