Where does OIL comes from?

Oil comes from ancient sea creatures that got buried under layers of mud and cooked into liquid rock over millions of years.

Imagine a giant pot of soup sitting on a stove for forever. That is essentially what the Earth did with tiny organisms to make oil.

Long ago, before dinosaurs walked the land, the ocean was full of microscopic plants called algae and tiny animals like plankton. When these little creatures died, their soft bodies sank to the bottom. Instead of floating up or rotting away, they got covered by thick layers of sand and mud. This blanket acted like a lid on a pot, trapping them in place.

Over time, more and more dirt piled up on top, making the pressure huge. The heat from deep inside the Earth started to cook this buried material. Just like butter melts when you put it in a warm pan, the organic matter melted into a thick, gooey liquid. This liquid is what we now call crude oil.

This oily goo did not stay where it was cooked. It slowly moved upward through tiny holes in the rock, looking for a place to rest. Often, it got stuck under a hard caprock layer that kept it from floating all the way up to the surface. This created an underground pocket or reservoir, like a sponge full of juice waiting to be squeezed.

Humans drill down into these pockets and pump the oil out to put in our cars and planes. So every time you see a car driving by, remember that it is running on the remains of tiny ocean life from millions of years ago, cooked up by the Earth’s heat. It is not magic; it is just nature’s slow-cooked recipe book.

The next time you fill up at the gas station, think of it as tapping into an ancient, liquid energy bank.
