How much oil is in the ocean?

Q: How much oil is spilled into the ocean every year? According to the U.S. Department of Energy, 1.3 million gallons (4.9 million liters) of petroleum are spilled into U.S. waters from vessels and pipelines in a typical year.

Herein, how did oil get under the ocean?

Formation and exploration of fossil fuels
Gas and oil form in the sea over a period of millions of years, as the remains of animals and plants sink to the ocean floor. Combined with particles flushed from the land, they are buried and compressed into layers of sediment several kilometres thick on the ocean floor.

Additionally, is there oil at the bottom of the ocean?

Just as there is a lot of oil beneath dry land -- well, not as much as there used to be -- there's also a lot of oil under the oceans. The ocean floor is actually a perfect place for oil to form, over the course of millions of years. Most things that die in the ocean eventually sink to the bottom.

How much oil is left in the world?

The Organization for Petroleum Exporting Countries reports that there are 1.5 trillion barrels of crude oil reserves left in the world.

Will we run out of oil?

"The world will run out of oil in 2030, and other fossil fuels in 2050." In the 1950s, a geologist named M. King Hubbert looked at oil production data from all of the major oil-producing countries in the world (at that time). The reality of the "amount of oil" is more complex.
Because most kinds of oil are less dense than water, most spilled oil floats on the water surface. It spreads out and is pushed across the water by wind and currents. Birds that float on the water surface and dive to feed can be oiled if they happen to be in the same place as an oil slick.
Of these, seeps are by far the single largest source, accounting for nearly half of all the petroleum compounds released to the ocean worldwide each year. Seeps are also the only natural source of oil input to the environment.

These clumps can exist from months to years in enclosed seas and for years in the open ocean—eventually, they degrade. But not all oil lives and dies at the surface. Between 10 and 30 percent of the oil is absorbed by sediments and suspended materials and deposited on the bottom of the sea.
Over the last six decades, it's only gotten deeper. In 1949, the earliest year with data available, the average depth of oil wells drilled was 3,635 feet. By 2008, the most recent data available, we were drilling an average of 5,964 feet, a slight decrease from the 2007 at 6,064 feet.

While not technically "oil spills," oil seeps from the ocean floor naturally release oil from subterranean reservoirs and represent the largest source of oil entering seas both in the United States and around the world.

Crude oil and natural gas naturally enter the ocean at areas known as "seeps." These hydrocarbons leak out of the ground through fractures and sediments, in the same way freshwater springs bring water to the surface.
Oil and Gas. Alaska still runs on oil. Alaska's North Slope has responsibly produced more than 18 billion barrels of oil since the discovery of the Prudhoe Bay oil field. Oil production has been the engine of economic growth in Alaska.
Rocks in Antarctica have been suggested to contain oil or gas. Even if this was the case (no drilling has taken place to find any) it is unlikely that they could ever be exploited commercially. Reliable authorities have estimated that it would cost over US$100 per barrel to get oil from Antarctica.
The notion that petroleum or crude oil comes from dinosaurs is fiction. Oil formed from the remains of marine plants and animals that lived millions of years ago, even before the dinosaurs. The tiny organisms fell to the bottom of the sea.
Oil and gas result mostly from the rapid burial of dead microorganisms in environments where oxygen is so scarce that they do not decompose. This lack of oxygen enables them to maintain their hydrogen-carbon bonds, a necessary ingredient for the production of oil and gas.
Shallow seas often had the correct conditions for oil formation millions of years ago. Specifically, something like an algae bloom has to die and sink into oxygen-free conditions on the sea floor, then that organic material gets buried and converted to rock over geologic time.
The most widely accepted theory for why the Middle East is loaded with oil is that the region was not always a vast desert. The oil was captured in place on the seabed by thick layers of salt. As the land in the modern Middle East region rose due to tectonic activity, the Tethys Ocean receded.
Largest oil reserves
  • Venezuela – 300 billion barrels.
  • Saudi Arabia – 269 billion barrels.
  • Canada – 171 billion barrels.
  • Iran – 158 billion barrels.
  • Iraq – 143 billion barrels.
  • Kuwait – 104 billion barrels.
  • Russia – 80 billion barrels.
  • United Arab Emirates – 98 billion barrels.
Saudi arabia or arabian plate oil and gas is so rich and prolific. The factors for such richness include the presence of so many petroleum systems over geological time including repeated and extensive source rock beds, excellent carbonate in good position and a long history of sedimentation.
Why do the USA consume so much oil compared to other countries? The US has a large population and an excellent network of roads. We are also a major air travel hub. In addition, oil makes sense as a fuel source for transportation, so absent government opposition market forces will cause oil to be a major energy source.
