The ultra-deepwater drilling market has fully recovered from the Deepwater Horizon disaster and even the owner of that rig -- Transocean (RIG -2.51%) -- is seeing improved results. As growing reserves are found in deepwater, Transocean, Noble (NEBLQ), Seadrill (SDRL), and Ensco (VAL) have been able to command $600,000 per day for rigs and keep them employed for months or even years at a time. With oil becoming harder to find onshore, energy contributor Travis Hoium thinks the profits these companies are reporting can continue to grow.
