There are two possibilities here: crude oil or natural gas. It's possible that oil shale and tar sands could be thought of as unrefined petroleum sources as well.

Is unrefined oil better than refined oil for cooking?

It depends on what you are looking for in a cooking oil. Refined and unrefined oils are made differently. Refined oils undergo additional processing to remove or modify components such as free fatty acids, pigments, odour compounds and other impurities. This can give the oil a more neutral taste and make it suitable for certain cooking applications. Unrefined oils, such as properly made cold-pressed oils, generally undergo less processing. Because they are not subjected to the same refining steps, they can retain more of the oil’s natural flavour, colour and naturally occurring minor compounds. However, unrefined does not automatically mean better or safer. The quality of the seeds, extraction method, filtration, moisture control, storage and cooking temperature all matter. For example, with cold-pressed mustard oil, I would not judge quality simply by its smell or pungency. The extraction and filtration process are equally important. In my experience as Ravi Pratap Rana, Founder of Pure Tatva, with 19 years of experience in the Pharmaceutical Industry, I prefer looking at the complete journey of the oil—from the seed and extraction process to filtration and storage—rather than judging an oil only by whether it is refined or unrefined. So, the better question is not simply “refined or unrefined?” but “How was the oil produced, and is it suitable for the way I intend to cook?”

What is another term for petroleum?

Another name for petroleum is crude oil, which describes its natural, unrefined state. It’s also called a fossil fuel because it forms from ancient plants and animals over millions of years.
