Our oil and gas comes out of the gulf with a direct pipeline and if that is not enough we import from the KSA along with a little fracking.
The key to remember is the PADD 3 refineries no doubt would like Canadian heavy. But Canada is under no obligation to sell it to us. Thus PADD 3 stays wedded to heavy oil, as in KSA heavy oil. Some US light oil goes to PADD 2 (Midwest), and a little to PADD 1 East Coast. Demand for US light oil is mostly external. Be it S America, or the EU. In competition with OPEC light oil.
US oil independent? No, we're very depended on external OPEC, and Canadian heavy oil. No matter how much frac oil is produced.
