We are looking for crude oil samples for some bioremediation experiments. We can't seem to find any from scientific chemical suppliers like Sigma. If anyone knows of any suppliers that would be great!
You should mention types or names of crude oil that you required . Heavy crude oils or light crude oils. Very light oils are jet fuel, Gasoline, ether, Kerosene, Petroleum, spirit, petroleum naphtha etc and heavy oil like Bitument. Then suppliers can be seen.
It would be better to take these samples from Azerbaijan, around Baku. It has a very ancient oil industry and 30,000 hectares of oil-contaminated land.
