Oil

The other weekend I went diving up at Yanbu.  Yanbu is just two hours north of where I live.  Yanbu is home to the Aramco Yanbu Oil Refinery.  Perhaps you've heard of it?  This little operation in the middle of no-where Saudi Arabia can produce up to 4.5 million barrels of oil a day.  I repeat.  4.5 million.  barrels.  A day.  Check out the nice brown haze that floats above the plant.
