Is there a citation for the US being a net exporter of oil? Last I checked, they were a net exporter of Gas, which is not the same as oil. Oil is refined to produce gas, and the US imports the majority of said oil.
Yes, for years now, the US has been the world's largest producer of crude petroleum because of the invention of hydraulic fracturing (fracking). Larger than Saudi Arabia.
The US still imports a lot of petroleum, but that is only because it has a comparative advantage in refining heavy crude. Most of the crude produced in the US is very light sweet crude, which is easier to refine. Some of that gets exported and refined overseas.
