Origins of Petroleum

Ancient civilizations utilized petroleum for various purposes, from lighting lamps to religious ceremonies, long before modern extraction methods. The substance itself is a complex mixture of hydrocarbons, differing in composition based on its source. While the prevailing view attributes its formation to organic matter over millions of years, some geologists propose an alternative theory suggesting an inorganic origin. Understanding the distinctions between sweet and sour petroleum, as well as light and heavy varieties, reveals the nuances of this vital resource.
