Back around 1990, I was a coach for the New York State B-B Gun Championship team in the Daisy Shooting Education Program, and the International B-B Gun Match was shot in Tulsa. Somebody in Tulsa had the brilliant idea of giving each of the participants a small bottle containing 1 or 2 ounces of crude oil as a souveneir at the banquet. A bottle was dropped by one of the kids (surprise!!!). The smell filled the whole banquet hall, I couldn't believe that something that small could stink that bad!
I can't imagine how bad the smell would be if you were surrounded by a few million gallons of it all day long. I would head out of there quickly.
