The Flemish pass is very deep and is in rough waters (think the movie Perfect Storm), but has the potential of the largest reserves. So expensive exploration wells are to be expected. Suncor (Petro-Canada) tried exploration there, but bowed out after a couple of 'dusters'. Now they are in a joint venture with Shell in the Shelburne Basin. Big risk, big potential wins, but that really is what the oil patch is all about. Same thing happens or has happened in the North Sea.
