This article can hardly be called “scientific” in the accepted sense - there are no graphs, formulas, diagrams, numerical values of supposed conditions inside the planet, and it cannot claim to fully explain all the processes occurring in the Earth’s interior. Most likely, this will remain a secret for a long time to come, with the opportunity to build “scientific” theories and mathematical models. However, the article is based on existing, already available, measurement data and observed natural phenomena, which are manifestations on the surface of processes occurring inside the planet. The totality of these manifestations, and there are more than a dozen of them, allow us to confidently speak about the correctness of the proposed idea. This article attempts to show the conditions under which oil and its accompanying fractions can appear their place in the body of the planet, and the processes that force it to rise to depths at which its extraction is possible.
