Saudi Arabia and OPEC have something to do with it, but so does ISIS or ISIL as the our government refers to them. Just like everything else, its a matter of supply and demand. I hadn't heard about the new discovery in Nebraska, obviously that would also drop prices. From what I've heard they are making $1,000,000 per day to fund their cause by selling off oil below what the world markets value is. I hope that the prices level off and stay at the current rate. Saudi Arabia and the other countries in OPEC are still making billions for their economies, and it would help our economy grow as well.
