Deep fluids include mantle-derived fluids (e.g., magma, gases, and hydrothermal fluids), fluids produced by rock dehydration during plate subduction, fluids formed by mineral dehydration during deep metamorphism, and constituents related to the upwelling of mantle materials. The circulation of deep fluids is typically accompanied by the transfer of heat energy from the deep Earth through the shallower subsurface to the surface. This process can significantly alter the composition and properties of sedimentary rocks, either directly (e.g., contact metamorphism) or indirectly (e.g., regional magmatic heating and compressional faulting), which can further influence the hydrocarbon generation and accumulation in sedimentary basins. Therefore, deep fluid activities affect the entire process of oil and gas generation, including the deposition and diagenesis of source rocks, reservoirs, and caprocks, oil and gas generation, migration, accumulation, preservation, and destruction.
The traditional view is that areas with extensive activities of deep fluids into the sedimentary sequences were once considered unfavorable for hydrocarbon exploration. However, in recent years, source rocks and oil-bearing formations have been encountered in igneous rocks in many sedimentary basins globally, accompanied by evidence for their participation in the accumulation of hydrocarbon accumulations. Previous studies have mainly focused on the effects of organic matter deposition, tectonics, and diagenesis on the formation of hydrocarbon accumulations, and little attention has been devoted to the role of deep fluids. Therefore, it is crucial to deepen our knowledge of the roles of deep fluid activities in exploring, evaluating, and exploiting oil and gas resources in the sedimentary basins.
We welcome original research regarding the ubiquitous impacts of deep fluid activities on oil and gas accumulations in sedimentary basins. Potential topics include but are not limited to the following:
• Tectonic events and the migration and release of deep fluids
• Carbon-hydrogen cycling in deep fluid interactions and growth of hydrocarbon precursor organisms
• Effects of deep fluid thermal energy transfer on source rock maturation
• Igneous reservoir rock formed directly by magma emplacement
• Dissolution, diapiric, thermal and anti-compaction effects of magma
