Over time, additional layers build up, burying the organic-rich material deeper within the Earth’s crust. This complex process relies on specific geological conditions where buried sediments, algae, and plankton accumulate over millions of years.
How Is Oil Made: Journey from Crude Reservoir to Refined Fuel
This industrial separation ensures that the complex mixture of hydrocarbons is transformed into the specific fuels and lubricants required by modern society. Kerogen, a waxy substance, transforms into liquid and gaseous hydrocarbons through a process known as catagenesis, typically occurring at temperatures between 60°C and 120°C.
Due to its lower density compared to water, the crude oil migrates upward through fractures and porous formations. The journey of crude oil from deep underground to the fuel in your tank begins with the transformation of ancient organic matter.

Primary and Secondary Recovery Initially, the natural pressure of the reservoir pushes the oil to the surface. Heavier residues may undergo further processing, such as cracking, to convert them into more valuable lighter fuels.
