A look at results from Noble(OTC:NEBLQ) and Diamond Offshore(OTC:DO) show mixed results coming from the very important ultra-deepwater market.

As we prepare to hear from ultra-deepwater-focused companies Seadrill (NYSE:SDRL)and Transocean(NYSE:RIG), it will be important to keep an eye on how these trends play out.
