The hydrogen / carbon ratio, another proof of the mineral origin of hydrocarbons          In all oil fields and wells it is observed that the hydrogen / carbon ratio increases with depth, showing a loss of hydrogen as the fluid rises and comes close to the surface.For reasons of density, one would imagine that the hydrogen-rich compounds, which are less dense, should be in the upper strata, while poor hydrogen substances, being heavier, should be in          deeper areas. But it's the opposite. Less dense compounds are in the lower levels of the Earth crust while   the denser are in the upper strata, closer to the ground surface. The only      logical process explaining this phenomenon is the upward migration of  hydrocarbons (due   to planetary degassing) and separation (usually by preferential oxidation) of hydrogen to      carbon during flow. T.Gold, 200|, argues that this process is   due to the metabolism of underground bacteria (hyperthermobacteria). According to this approach, methane and other gases would be in the lower layers, while the heavier hydrocarbons (eg gasoline and liquid oils in general) would be located in the  intermediate layers and bitumen coals and coals or on higher. These processes are  explained in more detail in the following chapters.  (To be continued in this blog). From the book "Inexhaustible? Gas and Oil" by D.Anton, Piriguazú Ed.
