I happen to live near the Anacortes Shell refinery and have a brother who is a supervisor there. A lot of their oil comes from the Alaska pipeline but that flow is slowing. There are always oil tankers out there delivering crude to be refineries. I think the Anacortes Shell refinery is mostly for jet fuel though. There are other refineries though, BP and Tesoro here and then in Martinez CA there is another Shell refinery along with others.
Jet Fuel is mostly Kerosene. As you can see from the capabilities of the units at the Anacortes Shell refinery, that is a smaller output than some of the other products.
