Powerwalker, to me where the support ships are is not indicative of oil/gas being there. The ships will be used to pull the rig back to Angola ( it was mentioned that it's next dock to get retrofitted). I don't expect they need any special supplies since no matter what they are cementing the hole ( good or bad). Most of the test equipment needed should already be onboard and the labs are back in Brazil using uplinks to get the data.......
I think someone would notice them stopping drilling which I do expect should be tomorrow. Then it is a waiting game to find out Good or Bad. I expect them to know that right now since TD would be tomorrow which meant they have been thru both reservoirs and have the drill measurements for oil or gas.
