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