I believe that the $93 a barrel price includes refining to a large degree, it is not thick black stuff just out of the ground.
When the price of oil is quoted, it is almost always in reference to the price traded at the New York Mercantile Exchange (NYMEX) for West Texas Intermediate delivered to Cushing, Oklahoma.
This is “raw” crude oil but of a good quality at the largest commercial stock location. It has not been refined at all.
