There has been much heated debate this week about how much more oil there is to come - probably a lot, but not necessarily offering up quite such generous tax revenue once the industry has been incentivised to drill and develop in deep water and hard-to-reach reserves.

At the same time, Global Marine has concentrated its fleet around rigs that can drill in more than 250 feet of water, as oil companies look farther and farther offshore for reserves in places like West Africa and Brazil.
The need to drill for oil in 5000 feet of water and 20, 000 feet below the ocean floor is a dramatic illustration of how the low hanging fruit are long gone and the lengths to which our addiction to oil will drive us.
