The "deep biotic petroleum hypothesis", similar to the abiogenic petroleum origin hypothesis, holds that not all petroleum deposits within the Earth's rocks can be explained purely according to the orthodox view of petroleum geology. Thomas Gold used the term "the deep hot biosphere" to describe the microbes which live underground. [6]
He is the founding father of modern abiogenic theory for origin of petroleum, which states that some petroleum is formed from non-biological sources of hydrocarbons located deep in the Earth's crust and mantle. He graduated from Leningrad Mining Institute in 1922, obtained a Dr.Sc. in Geology and Mineralogy in 1936, and become professor in 1941.

In 1945, Porfiriev began a new phase of his career, beginning with his relocation to Lviv in the Western Ukraine. There he organized the Lviv Branch of the Institute of Geological Sciences, the Lviv Seological Society, the Physical Geology Department at Lviv State University and established the Oil and Gas Fields Geology and Exploration Department at Lviv Polytech Institute, the first ...
Petroleum, or evidence of its immediate occurrence, can be found on the surface of the Earth. Oil seeps can be found near a fault zone, where the movement of Earth's crust can expose petroleum source rock, and thus the crude oil itself. [15] They can also be found on the ocean floor, and can be found using satellite imaging. [16]
An alternative mechanism to the one described above was proposed by Russian scientists in the mid-1850s, the hypothesis of abiogenic petroleum origin (petroleum formed by inorganic means), but this is contradicted by geological and geochemical evidence. [75] Abiogenic sources of oil have been found, but never in commercially profitable amounts.
