the price of oil is now high enough to make shale oil deposits economically feasible.

I think I know the answer BUT...If the price of crude is 80% of the price of gas:

How come when Bush-gas was $4.00, oil was at $140 a barrel, but now that Obama-gas is $4.00, it's only $90?

While the cost of crude is the most important element in the cost of refined gasoline, it's not the only cost.

For one thing, demand isn't nearly as high now as it was before the Obama economy. There is some excess in refinery capacity.
