Mantle-derived fluids have significant implications for oil and gas generation in sedimentary basins. These fluids can influence the quantity and quality of hydrocarbons produced by providing both energy and hydrogen necessary for the conversion of kerogen into oil and gas. Hydrogenation by these fluids can increase the hydrocarbon production rate at every stage of organic matter evolution, which is particularly important for humic kerogen. The injection of hydrogen-rich fluids into a sedimentary basin can promote oil generation differently in a closed system for various types of source rocks.
Deep fluids can also improve the primary productivity of sedimentary basins and carry abundant inorganic hydrogen, contributing to the hydrocarbon generation process. The exchange of crust-mantle material and energy suggests a connection between oil, gas, and geothermal resources in sedimentary basins, indicating that mantle-derived fluids might play a role in the overall energy resource potential of an area.
For example, studies on the East Java Sedimentary Basin in Indonesia have shown that the system is fueled by the lateral migration of mantle-derived fluids that trigger reactions within the organic matter, leading to the production of oil and gas. This highlights the significant role that these fluids can have on the generation and migration of hydrocarbons in sedimentary basins.
In summary, mantle-derived fluids can enhance oil and gas generation in sedimentary basins by providing necessary hydrogen and energy, thus playing a crucial role in the hydrocarbon system of these basins.
