It might sound surprising that the U.S. does not allow the export of one of its most valuable and plentiful natural resources — but in the case of crude oil, it's true.

A lot of Texas politicians would like to see the ban overturned, and soon lawmakers in the U.S. House of Representatives may vote on just that.  But why is there a ban in the first place?


Anyone who spends time looking at how oil is drilled for and refined around the world comes to notice something strange. The names people give to different types of crude oil can sound surprisingly delicious.

In reporting on the role that benchmark oil prices play in moving the price of gasoline,  I was introduced to one person who had made a game out of it. Rice University student Aruni Ranaweera created the quiz "Beer, Coffee, Crude" to test her classmates' ability to distinguish between types of crude, types of beer, and blends of coffee.  It's harder than is sounds. Go ahead, crack open a can of Tia Juana Light and give it a shot.
