Tiny creatures like algae and zooplankton, along with larger marine animals, absorbed energy from the sun and formed the base of the food chain. Today, the industry has advanced significantly beyond collecting surface seepages.
How Was Oil Formed Over Millions of Years Beneath the Earth

Due to its lower density compared to the surrounding rock, it becomes buoyant and begins to migrate upward through porous rock formations. It is transported to refineries, where it is heated and processed in complex distillation columns.
