Not all, petroleum is a complex mixture of organic compounds consisting mainly of carbon and hydrogen, along with small amounts of other elements like sulfur, nitrogen, and oxygen. So, stating that something is "Not a petroleum product" indicates that it is not derived from crude oil.
A material that contains hard-to-mine petroleum is oil shale. Oil shale is a sedimentary rock that contains kerogen, a solid organic material that can be converted into synthetic crude oil through processes like pyrolysis. Extracting petroleum from oil shale is more challenging and costly compared to conventional oil extraction due to the need for extensive heating and processing. As a result, while it represents a significant potential resource, its economic viability often depends on oil prices and technological advancements.
