The abiogenic hypothesis of petroleum formation, which suggests that petroleum originates from deep carbon deposits within the Earth, is supported by a number of modern researchers and institutions. Notably, the Royal Institute of Technology (KTH) in Stockholm has reported findings that regained some support for the abiogenic hypothesis in 2009. The modern Russian-Ukrainian theory of deep, abiotic petroleum origins also plays a significant role in this field, recognizing petroleum as a primordial material of deep origin.

Researchers such as Nikolai Alexandrovitch Kudryavtsev, who proposed the modern abiotic theory of petroleum in 1951, have contributed to the development of this hypothesis. His work analyzed the geology of petroleum reservoirs and supported the idea that petroleum is not solely of biological origin.

While the abiogenic hypothesis is not widely accepted in mainstream science, these researchers and institutions continue to explore the possibility that petroleum may be continuously generated deep within the Earth, challenging the traditional biogenic theory of petroleum formation.
