No, I don't think we're proceeding blindly. A water depth of 2,600 metres is not uncommon these days. That same drilling unit just finished a well in 1,900 metres of water south of Newfoundland. The technology exists for up to 10,000 feet of water depth, and the equipment, if it's used properly, should contain well bore fluids. Our primary focus as a drilling contractor--and I'm sure other presenters who have been here have said the same--is to make sure you do not lose control of that pressure. By having two barriers, if you manage that plan correctly, you should never, ever, have uncontrolled release of fluids at surface.
