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 ...

Resource Geology journal publishes papers on economic geology, geochemistry, and environmental geology, with an emphasis on earth sciences of mineral deposits. Abstract. The two theories of abiogenic formation of hydrocarbons, the Russian-Ukrainian theory of deep, abiotic petroleum origins and Thomas Gold's deep gas theory, have been considered ...

[1] [38] Modern geogologists think that commercially profitable deposits of abiotic petroleum could be found, it's just that all current deposits can already be explained by biotic theories, and no current deposit has convincing evidence that it originated from abiotic sources. [38]

This so-called "abiogenic" petroleum might seep upward through cracks formed by asteroid impacts to form underground pools, according to one hypothesis. ... but never in commercially profitable ...

The lack of a clear and irrefutable success in locating abiotic petroleum in commercial quantities is problematic. This year, Ahmed (2014) advances the argument that Siljan Crater oil is unambiguously of biogenic origin due to the copresence of molecules of "known" organic origin (specifically terpane and sterane biomarkers).
