Refinement and Utility: Turning Crude into Products After extraction, the raw crude oil is transported to refineries. As the world transitions toward sustainable energy, the legacy of oil continues to shape economies and geopolitics, even as society seeks cleaner alternatives for the future.
How Oil Migration Toward Surface Rock Happens
Once a reservoir is identified, drilling allows the oil to be extracted, bringing the ancient carbon stores back to the surface for refinement and use. Because it is less dense than water and rock, it migrates upward through porous formations like sandstone.
The story of where did oil come from begins millions of years ago, deep beneath ancient seas and dense prehistoric forests. This combination cooked the organic material, a process known as diagenesis and catagenesis.
How Oil Migration Toward Surface Rock Occurs
In oxygen-poor environments, this organic matter was prevented from fully decomposing and was gradually covered by layers of mud and silt. Humans locate these deposits using seismic surveys and geological mapping.
