  • Summary

    A new finding over the past decade is the stability – and even potential synthesis – of hydrocarbons at depth in Earth. Of course, this has been a highly controversial area of research for decades, but recent evidence has been obtained from natural orogenic geological settings, thermodynamic simulations, and observations of seafloor samples. This chapter reviews this new evidence while highlighting the importance of the physical state of C-O-H fluids contained in rocks on the transport of alkanes like methane, propane, and octane, the impact of pore space and fracture confinement on fluid reactivity, and how reactivity under confinement varies from bulk fluid properties.
