DrD, for mine, the clincher is the question further on comparing Zeus to Artemis - and how the traps are different.
I'm no petrologist, but the anticline trap of Artemis and the syncline trap of Zeus was a critical distinction IMO.
8:10min to 9:40 min mark - whoever asked that question needs congratulating.
It's hard to see how Petrobras wouldn't know what they have bought into.
