Its actually crude oil that is there underneath the land at very long depths. This is due to degradation of trees, plants, animals, and any biodegradable material over millions of years. In order for it to happen there must be massive amount of pressure and time. Natural gases can be extracted during the process of mining for crude oil which is released due to the high pressure inside earths surface. How petroleum products are made.? It is done by first mining crude oil or shales which is a raw material. This is further treated in distillation column at different temperature, pressure and other conditions. Usually heavier density products like tar, diesel, kerosene etc. are obtained at bottom. As lighter the products like petrol, LPG, CNG it is obtained by reaching towards top in the column. This is not the end, the products coming out are more than 100 types which some needs extra processing like refining(petrol).
