A top authority on oil reservoir management and upstream technology called the BP oil spill in the Gulf of Mexico a "Black Swan" event that, however catastrophic, has the potential to improve drilling practices in particular and the industry in general.

Fire boats battle a fire at the off shore oil rig Deepwater Horizon April 21, 2010 in the Gulf of Mexico off the coast of Louisiana.

“The heart and soul of the whole issue is that this is a Black Swan event,” Nansen Saleri, CEO of Quantum Reservoir Impactand a former executive at Saudi Aramco, told CNBC Wednesday.
