Crude Oil PricesCrude Oil Prices - Crude oil prices mainly for the USA. Details on crude oil prices per barrel, the crude oil price history and what events caused the price rises, the current crude oil prices, how crude oil is refined and more.



While the global demand for crude oil production continues to rise, supplies remain relatively constrained. Oil companies explore the world searching for new sources of oil.


Crude Oil Production

New sources of oil are often located in areas that are increasingly challenging to develop, such as the deep water or oil sands.

How Is Crude Oil Produced? Wells are drilled into oil reservoirs to extract the crude oil. "Natural lift" production methods that rely on the natural reservoir pressure to force the oil to the surface are usually sufficient for a while after reservoirs are first tapped. For crude oil production in some reservoirs, such as in the Middle East, the natural pressure is sufficient over a long time. The natural pressure in many reservoirs, however, eventually dissipates. Then the oil must be pumped out using "artificial lift" created by mechanical pumps powered by gas or electricity.

Over time, these "primary" methods become less effective and "secondary" production methods may be used. A common secondary method is "waterflood" or injection of water into the reservoir to increase pressure and force the oil to the drilled shaft or "wellbore." As crude oil production continues, Eventually "tertiary" or "enhanced" oil recovery methods may be used to increase the oil's flow characteristics by injecting steam, carbon dioxide and other gases or chemicals into the reservoir.

Extracting oil (or "bitumen") from oil/tar sand and oil shale deposits requires mining the sand or shale and heating it in a vessel or retort, or using "in-situ" methods of injecting heated liquids into the deposit and then pumping out the oil-saturated liquid.

The Middle East is the world's largest crude oil production region, followed by Russia and the United States.

Potential new energy sources are carefully researched, mapped and tested, using seismic technology to survey the earth below the surface. Computer-generated three-dimensional imaging helps scientists identify potential new sources of oil and natural gas located miles beneath the surface of the earth.

Deepwater locations are home to some of the world's largest free-standing structures that, on dry land, would dwarf structures like the Empire State Building and Eiffel Tower. These gigantic structures stand thousands of feet above the seafloor, enabling producers to drill miles into the earth to reach the energy source for crude oil production.
