As a subject matter expert in the field of geology and petroleum engineering, I can provide you with a comprehensive understanding of the concept of oil age and how it is determined. The age of oil refers to the time that has elapsed since the organic material that eventually became petroleum was deposited and began its transformation into hydrocarbons. This process can take millions of years, and the age of oil can be a critical factor in understanding the geological history and the potential for hydrocarbon reserves in a given area.
Red Flag: The provided information suggests that the Jurassic and Cretaceous periods were significant times for oil formation, which is accurate. These periods are indeed known for their conducive conditions for the formation of oil and natural gas deposits. However, the question of dating oil is complex and requires a nuanced approach.
The process of oil formation involves several stages:
1. Organic Matter Accumulation: The process begins with the accumulation of organic matter, primarily from microscopic marine organisms that die and settle on the seafloor.
2. Diagenesis: Over time, this organic matter undergoes diagenesis, a transformation process that involves the physical and chemical changes of the material under the influence of heat and pressure.
3. Catagenetic Phase: As the temperature and pressure increase with burial, the organic matter enters the catagenic phase, where it starts to transform into a waxy substance known as kerogen.
4. Metagenesis: Further heat and pressure lead to the metagenesis phase, where kerogen breaks down into smaller hydrocarbon molecules, which eventually form crude oil and natural gas.
The dating of oil is not as straightforward as radiometric dating of rocks because oil itself does not contain the necessary isotopes for such dating methods. Instead, scientists use a variety of indirect methods to estimate the age of oil:
- Biomarker Analysis: By identifying and analyzing specific organic compounds called biomarkers, which are preserved in the oil and are characteristic of the organisms that produced the organic matter, scientists can infer the age of the oil.
- Stratigraphic Correlation: The geological layers in which oil is found can be correlated with well-dated rock formations, providing an indirect age estimate.
- Isotopic Ratios: The ratios of certain isotopes in the oil can provide clues about the age of the source organic matter.
- Geochemical Techniques: Advanced geochemical techniques can help determine the maturity of the oil, which is related to the amount of time it has been subjected to heat and pressure.
The development of a method for age-dating oil, as mentioned in the provided information, would be a significant advancement in the field. Such a method could potentially use one or a combination of the above techniques to provide a more precise dating of oil samples.
In conclusion, the age of oil is a complex subject that involves understanding the geological history of the organic matter that forms petroleum. While the Jurassic and Cretaceous periods were indeed important for oil formation, dating the oil itself requires sophisticated methods and careful analysis of various geological and chemical indicators.

Method for age-dating oil is developed. STANFORD -- The Jurassic (180 million to 140 million years ago) was a very good age for oil formation. So too was the Cretaceous (140 million to 65 million years ago). But, until now, oil industry experts have lacked a direct way to date their crude.Aug 4, 1994
