Variability: The Spectrum of Crude Oils Not all oil is created equal, and the specific composition varies dramatically depending on the geological formation. The proteins, fats, and carbohydrates underwent a process known as diagenesis, breaking down into a waxy substance called kerogen.
Understanding Hydrocarbon Structure in Crude Oil
The type of kerogen present is a critical factor in determining whether a deposit will yield oil, natural gas, or bitumen, depending on the geological conditions it experiences. From Organic Matter to Kerogen As the buried organic layer accumulated under increasing pressure and heat, a complex chemical transformation occurred.
Kerogen is a large, insoluble molecule that serves as the solid precursor to liquid and gaseous hydrocarbons. Aromatics: Stable ring structures that, while less prevalent, are highly reactive and valuable for chemical manufacturing.
The Molecular Building Blocks of Crude Oil and How They Dictate Its Type
Conversely, heavy crude oil is thick and dense, containing a higher concentration of large, complex molecules that are difficult to extract and refine. Over time, this biological material was cut off from oxygen, preventing complete decay and creating a concentrated organic soup that would eventually transform into hydrocarbons.
