Deduction of Inorganic Oil Formation Theory from the Perspective of Earth Carbon Cycle and Feasible Scheme for In-situ Synthesis of Clean Energy in Depleted Oilfields

1.This paper proposes a novel perspective on the origin of petroleum, challenging the mainstream kerogen oil formation theory by hypothesizing that petroleum may be a product of the Earth's internal inorganic carbon cycle—generated through catalytic reactions of CO₂ and H₂ under high-temperature, high-pressure underground conditions with natural mineral catalysts (e.g., serpentine). 2.Based on this theory, a feasible technical scheme is presented: injecting CO₂, H₂, and water into completely depleted oilfields to realize in-situ synthesis of clean petroleum, achieving a closed carbon cycle to address both the global energy crisis and climate change. 3.An appendix provides a low-cost laboratory verification scheme (total budget ~7800-12500 RMB, 30-day duration) to validate the core reaction logic, inviting global researchers to collaborate on testing and verifying this hypothesis.
