Why do i get the idea from tv reporting of Obama's angle on this,
that he seems to be revelling in the part of the 7th Cavalry riding
to the rescue ?
Simple. It's good politics. Doesn't accomplish anything practical though... Even the current energy secretary knows very little about the oil industry as a whole, but you can bet he and his team have been doing some late night studying.
Yesterday, the senator asking about whether it was good practice to displace the riser with seawater before setting the plug or after probably didn't know what a subsea riser was last month. The question was inane. And the honest response 'I don't know.' just didn't seem to be good enough for him.
I doubt if anyone in the industry could answer that and it would require a worldwide survey across every oil company on the planet to even find that out. An no doubt, some companies wouldn't respond nor know themselves. And once it is answered... will it help fix the problem? Of course not...
But by putting 'big oil' on the spot publicly, he makes brownie points towards his next election because he was 'tough on big oil'. Wow, gee... yeah, I'll vote for him... NOT.
By the way, based on what I've heard and read recently, the riser displacement before or after the plug would have made no difference other than delaying the accident by a few hours.
The 'negative pressure test', as the media like to call it, or leak down test, as the industry calls it internally, was apparently not considered a good test contrary to earlier reports that they did the tests and they proceeded. This just came out yesterday publicly.
So there was apparently some early warning they had gas migrating to surface. Why it was not heeded is unknown to the public at this point in time. There are also new reports now that the BOP stack had a hydraulic leak. That could mean a lot or not... the stack has multiple backup systems. What is clear... the stack didn't work when it was needed most.
More will come out as time passes, as all accident information does.
FWIW,
