A large part of the refineries in Texas are set up to process heavy crude oil (supplied by Mexico, Venezuela, Saudi or Canada). Mexico supplies the refinery that they now own 100% in Deer Park (formerly was a joint venture with Shell). The fuel that is made there goes back to Mexico (because Mexico can't keep their refineries running). Venezuela is off the market (due to a communist dictator that has destroyed their oil business with the largest oil reserves in the world). The US wants to block importing oil from Russia. Saudi can supply some of the needs for the heavy oil as can Canada (in much larger quantities). The Biden administration needs to approve the pipeline to get more heavy crude from Canada to Texas.

The oil produced from the _______ process is light crude and is not suitable to be processed in a lot of the refineries in Texas. That is why Texas exports a lot of the light crude to the older refineries in the northeast US or outside of the US. They then import import the heavy crude that many of the refineries in Texas need.

As for as selling gasoline at a lower cost just in Texas, that won't happen for a lot of reasons. The best way to get prices down is to produce a lot more crude oil and go back to being a net exporter as we were during the Trump era.
