Petroleum—or crude oil—is a fossil fuel that is found in large quantities beneath the Earth’s surface and is often used as a fuel or raw material in the chemical industry. It is a smelly, yellow-to-black liquid and is usually found in underground areas called reservoirs.
Where is petroleum first found?
The petroleum industry is first encountered in the archaeological record near Hit in what is now Iraq. Hit is on the banks of the Euphrates river and is the site of an oil seep known locally as The Fountains Of Pitch. There asphalt was quarried for use as mortar between building stones as early as 6000 years ago.
Why is petroleum found underground?
A fossil fuel, petroleum is formed when large quantities of dead organisms, usually zooplankton and algae, are buried underneath sedimentary rock and subjected to intense heat and pressure. Petroleum is recovered mostly through oil drilling (natural petroleum springs are rare).

Who first discovered petroleum?
Barely seven years after Edwin L. Drake drilled the world’s first oil well in 1859 at Titusville, Pennsylvania, USA, history registered another exploration of the black liquid gold, in the largest continent. In 1867, a large group of men were engaged in laying railway tracks for the Assam Railway and Trading Co.
How is petroleum produced?
Petroleum is a fossil fuel, meaning that it has been created by the decomposition of organic matter over millions of years. Petroleum is formed when large quantities of dead organisms–primarily zooplankton and algae–underneath sedimentary rock are subjected to intense heat and pressure.
How did oil get so deep?
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.
Which Desert is rich in petroleum?
In fact, the Libyan Sahara Desert contains unmistakable glacial scars and Antarctica has extensive coal deposits–and very likely abundant oil and gas–that establish that their plates were once at the other ends of the earth….
