In terms of research, the question should be directed to my colleague from the Canadian Association of Petroleum Producers, because we are the downstream association. But my view on the prospects for hydrates is that it means yet more supply, in fact significant quantities more, which on balance is a good news story and negates any suggestion that we're running out of the fuel. Obviously there are all kinds of technical challenges with its recovery, which again I would direct to upstream colleagues, but the story is a good one because the supply picture continues to get better.
Our conventional supply picture is getting better; our unconventional supply picture has made it better still. Hydrates would make it better still.
