The Origin of Oil: Organic or Abiotic?
Discussion about whether oil has an organic or abiotic origin. The latter theory is popular in Russian scientific circles. We are agnostic on this question, although we never understood how oil can be of organic origin and yet seems to concentrate in huge oil fields.
Perhaps the real answer is that oil can be either of organic or abiotic origin.
Perhaps the largest oil field on earth Ghawar is of abiotic where shale oil is of organic origin.
