I just looked it up, in july 2009 there were 200 rigs drilling for oil in the US. In march 2014 there were 1400 rigs drilling for oil. Seven times more than 5 years ago. Oil production has increased from 4.5 million barrels per day 5 years ago to 8.5 million barrels per day in
2014. Gas was about $1.89 per gallon 5 years ago in my area and now it is about twice that.
