Abiogenic Origin of Hydrocarbons
1. If a part of hydrocarbon compounds could get generated in the asthenosphere of the earth (80 – 200 km below the surface) and migrate through the deep faults into the crust of the earth; and essentially, if petroleum amounts to primordial material of deep origin, then, why did the theory on ‘abiogenic origin of hydrocarbons’ was not given due importance?
2. Is there no science in the absence of reliable and reproducible experimental results (which demand high P & T; carbon (carbon itself, carbonates, CO2) and hydrogen (water, hydroxyl group of minerals) sources; presence of FeO; along with a thermodynamically-favorable reaction-environment/reducing conditions)? How easy would it remain to replicate polymerization of hydrocarbons @ laboratory-scale, which may demand temperature up to 1500 degrees C and pressures up to 70 kbar?
What is the essence of CaCO3-FeO-H2O system that spontaneously generates the suite of hydrocarbons?
3. If abiogenic deep origin of hydrocarbons confirms the presence of enormous, inexhaustible resources of hydrocarbons, then, where do we stand, with reference to COP28/Net-zero emission? Are there ways to explore the structure, size and location of the world’s hydrocarbon reserves considering abiogenic theory?
4. Feasible to replicate the terrestrial mud volcanoes releasing a dominant abundance of thermogenic methane (in deep-reservoirs/petroleum-seepage-systems) @ laboratory-scale?
Read a whole volume of Chemial Geology Vol 71 1988 M. Schoell ed. That is devoted to this question.
