How is crude oil formed

The black, viscous liquid that powers much of the modern world, crude oil, is a complex mixture of hydrocarbons forged over millions of years deep within the Earth’s crust.

Understanding its formation is crucial not only for the energy industry but also for grasping the vast timescales and intricate geological processes that shape our planet. This article will delve into the fascinating journey of how organic matter transforms into the valuable resource we know as oil.

The Beginning: Organic Matter Accumulation

The genesis of oil begins not with geology itself, but with the biology of ancient life.

How is oil formed step by step

Primarily, the source material for oil is plankton – microscopic organisms that thrive in the world’s oceans and lakes. These tiny plants (phytoplankton) and animals (zooplankton) utilize photosynthesis and consume other organic matter, thus storing energy within their cells.

The Marine Environment

The majority of oil deposits originated in marine environments.

These ecosystems, teeming with life, create a continuous cycle of growth
