Is there a market for barrels? - I would assume most oil is stored in tanks, transported via pipeline to harbor, loaded onto tanker and oil trucks with never seeing a barrel and the barrel mostly serving as a unit for calculation.
As conductr says, barrels are still commonly used for refined oil products. I worked at a gas station as a teenager, and we sold barrels of oil to farmers. They worked on a deposit system, we'd buy back the barrels. Or more commonly the farmer brought back the empty when buying a new barrel so didn't get charged the deposit.
I have one for making into a little stove with a kit from Amazon and lots of people use metal barrels for burning trash in rural areas. They are super cheap though like $10.
I live in Texas like another reply and those barrels are all over the place. They get used for everything from trash bins to bbqs. Also, old drill pipe is used for 99% of the pipe fences you see on farms/ranches.
Im in Texas, lots of oil, and have seen market for such barrels when shopping for shipping containers and IBC totes in the past. Usually I find sellers of these things near distribution hubs.
The barrels never had been used for crude oil when I’ve inquired. Sometimes a refined oil product likely used as a raw material for a manufacturing process, but never crude. I think it’s never transported in such small quantities to make sense of using actual barrels. It’s more so a unit of measure, probably with some valid historical context.
My understanding is it’s most likely transported from a well via a pipeline and may need a short trip in a truck or train (tanker style) to get to the pipeline from the well. The well itself usually has a collection reservoir to allow for 24/7 extraction.
I don’t know exactly I’ve just been vaguely around oil industry and engineers my whole life due to where I live.
