Thank you, Mr. Chair.
It's always a challenge to follow Mr. Allen and Mr. Cullen on these kinds of technical issues.
Mr. Roche, the testimony we've heard up to now, combined with observations of what's happened in the gulf, has led the committee to the notion that a relief well would be an approach that would compensate for the breakdown of the two-barrier technology you've described. You have said, though, that the trajectory issues with respect to a relief well at the depths we're talking about would militate against a simple interface. Yet, in the gulf that is the only backup that appears to be possible at this point. Everything has failed, and they're talking about a same-season relief, something which in the arctic might be a little bit difficult.
From a technical and a professional perspective, how do you marry the reality of what's happening in the gulf with the incongruity of your answer with respect to trajectories? Would you not say that the trajectory issue against all of the other options and the failure of the two-barrier system is the only alternative, and that professionally, from an engineering perspective, you should find a resolution to the trajectory issue and get on with a relief regime in deep-sea drilling?
