It makes sense to have that refinery close to its raw material source.
That is only half the equation. Transporting the products can be just as expensive. Refineries also have to be located near pipelines and chemical plant operations to be economical, or they have to be tiny like this one with a very limited output.
I suspect most of the Naptha they produces and all of the residual is going to need a pipeline for economical transport.
Also they need support industries. Operation and Maintenance becomes significantly more expensive the farther you have to travel for the many needs.
