The US Energy Information Administration (EIA) divides the country up into five regions as follows:
To give some feeling of where the oil in the US comes from, we can look at a stacked area graph of production by PADD region (since 1981, ie comfortably after the peak in 1970):
To make it clear where the minor resurgence now is coming from, we can look at the same data on a line graph. This goes through June 2010:
The resurgence has not come across the board - the West continues an unbroken decline, for example. Instead, the recent increases are mainly focussed in the Gulf States (where production has now been restored to a level similar to that before Hurricanes Katrina and Rita), and the Midwest, which has been trending upward after a long decline.
