Russian scientists are reviving a previously abandoned theory that oil originates from deep within the Earth, independent of organic matter. A major drilling project is planned in Siberia to test this hypothesis, aiming to reach depths of several kilometers. The project seeks to locate oil formed through geological processes, rather than the decomposition of plant and animal life. This undertaking represents a renewed focus on unconventional oil exploration methods. If successful, the discovery could significantly alter understanding of oil formation and potential reserves. The drilling operation is expected to begin soon, marking a substantial investment in this long-held, yet unproven, geological concept. The potential implications for global energy resources are considerable.
