Thus the arguments for/against abiogenic oil rest on (1) isotopic ratios, and (2) other geochemical indicator ratios; see e.g. Jenden (1993). Höök (2010), in a review of the arguments for biogenic and abiogenic formation processes, say: However, theoretical studies, laboratory verification and discoveries of trace amounts of abiotic oil do ...

Main arguments against abiogenic origin of oil are the following: (1) ... The oil production from extension zones exceeds 85%, while in compression areas wells are characterized by low and unstable yields, which decrease substantially as formation pressure falls up to 10-20 mPa. Wells located in areas of anomalous compression are ...

"[Abiogenic] origin of oil has been proposed by many before, but there are arguments pro and contra," said Alexander Goncharov, a geophysicist at the Carnegie Institution. On supporting science ...

The abiogenic petroleum origin hypothesis proposes that most of earth's petroleum and natural gas deposits were formed inorganically, commonly known as abiotic oil. [1] Scientific evidence overwhelmingly supports a biogenic origin for most of the world's petroleum deposits. [2] [3] Mainstream theories about the formation of hydrocarbons on earth point to an origin from the decomposition of ...
