the A biogenic theory holds that hydrocarbons were a component of the material that formed the Earth through a creation of solids some 4.5 billion years ago. With increasing internal heat, liquids and gases were liberated on because they were less dense than the rocks. Buoyancy forces drove them upward in favourable conditions. The upward journey from the regions of origin would be damned temporarily in porous rocks at depths that our drills can reach and from which we then derive commercial petroleum.
