Abiogenic petroleum is created through non-biological means, unlike fossil fuels. It is thought to come from deep carbon deposits within the earth and has been studied since the 18th century. Theories continue to be debated, including the existence of an underground biosphere.
Abiogenic petroleum is understood to be oil that is produced deep within the earth through a variety of non-biological means. In this respect, abiogenic oil would be different from oil produced from fossil fuels, which are found within the earth in various places around the world. At the same time, abiogenic petroleum would still be considered a form of natural petroleum, as the product would be created using natural components and a series of natural occurrences.
In general, abiogenic oil is thought to be a product of deep carbon deposits within the planet. Some theories of the origin of abiogenic oil argue that the carbon has undergone a natural process that dates back to the formation of the earth. When this is the case, the theory usually views the process as involving the upward movement of carbon-rich fluids from the earth’s core into sections closer to the globe’s outer crust.
The first theories of oil development are generally believed to be the work of Mikhail Lomonsov during the 18th century. The concept of natural petroleum of this nature continued to be refined during the 19th century through the work of both Russian and French chemists, who began developing the first abiogenic theories of petroleum.
Further development of an abiogenic petroleum theory also continued in the latter part of the 20th century. One of the latest theories includes the concept of the existence of an underground biosphere that releases thermophilic bacteria into the planet’s crust on an ongoing basis. Proponents of abiogenic oil often support this theory by calling attention to the presence of biomarkers in oil extracted from the earth.
Theories of the origin of abiogenic petroleum continue to be a source of discussion and controversy in the scientific community. However, the idea of petroleum originating as a fossil fuel tended to be more commonly accepted and taught in a number of countries around the world.
