Crude oil is formed from the remains of dead organisms (diatoms) such as algae and zooplankton that existed millions of years ago in a marine environment. These organisms were the dominant forms of life on earth at the time.
How was oil created in the earth?
The formation of oil begins in warm, shallow oceans that were present on the Earth millions of years ago. This material then lands on the ocean floor and mixes with inorganic material that enters the ocean by rivers. It is this sediment on the ocean floor that then forms oil over many years.
What was oil made from?

What is the origin and supply of oil?
The Mysterious Origin and Supply of Oil. A so-called fossil fuel, petroleum is believed by most scientists to be the transformed remains of long dead organisms.

How did oil become a strategic energy source?
Beginning with World War I, oil became a strategic energy source and a tremendous geopolitical prize. In the 1930s, Gulf Oil, BP, Texaco, and Chevron were involved in concessions that made major discoveries in Kuwait, Saudi Arabia, and Libya.
What are the components of oil production?
Oil Generation There are three necessary components in the generation and accumulation of oil: source rock, reservoir rock, and cap rock (Fig. 1). [1] Source rock is a rock with high concentration of organic material that can be transformed into oil under the action of high temperature.
What is the history of oil and gas energy?
Throughout human history, before the modern history of the oil and gas industry even begins, energy has been a key enabler of living standards. To survive in the agrarian era, people burned wood for warmth and cooking. In addition to use as a building material, wood remained the chief global fuel for centuries.
