Technically speaking it is actually unlikely that we will ever 'run out' of oil. Oil, and all other fossil fuels are finite resources by their very nature, but as easier reservoirs of oil are exhausted other more complicated reservoirs become economically viable.
When oil is generated underground its is less dense than water, so it floats up through the pores and fissures. Some oil gets to the surface, but some might get stuck below a rock layer that doesn't have small pores or fissures - like a clay, for example. This trapped oil is like a bubble.
From eons to hours: new process can pressure-cook algae into crude oil. A new discovery could let scientists artificially create crude oil in under an hour, accelerating a natural process that normally takes at least a few million years to complete.
Oil is defined as a fossil fuel that's made from carbon and hydrogen. It takes a very long time and very specific circumstances for oil to form, and most of the oil that we use today started forming millions of years ago.

Reserves of oil are huge because it was created over millions of years. Assuming widely accepted organic theory then yes, some oil is still being created as proper rocks, rich in organic matter are being heated under correct pressure in the earth crust.
Energy independence is highly concerned with oil, the source of the country's principal transport fuels. In total energy consumption, the US was between 86% and 91% self-sufficient in 2016. In May 2011, the country became a net exporter of refined petroleum products.

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.
We Will Never Run Out of Oil
There will still be oil in the ground 10 years from now, and 50 years from now and 500 years from now. This will hold true no matter if you take a pessimistic or optimistic view about the amount of oil still available to be extracted.Soon after America's first commercial oil well of 1859, a small group met in northwestern Pennsylvania and decided a 42-gallon barrel was best for transporting their oil. When filled with oil instead of fish or other commodities, a 42-gallon “tierce” weighed 300 pounds.
According to the US Energy Information Administration, about 75% of the 6.79 billion barrels of petroleum used in the US in 2012 were gasoline, heating oil/diesel fuel, and jet fuel.
Crude oil is used to make the petroleum products we use to fuel airplanes, cars, and trucks; to heat homes; and to make products such as medicines and plastics. Although petroleum products make life easier, finding, producing, and moving crude oil may have negative effects on the environment.
About 8% to 10% of our total oil supply goes to making plastic. It is estimated that about 12 million barrels of oil a year are used in making the plastic bags used in the US. An average American throws away about 10 bags a week. That's 520 bags a year–a fuel equivalent of 60 miles of driving.
Oil and coal supposedly come from trees and animals that were buried for millions of years. They are often thousands of feet deep. Over the next billion years, heat and pressure "cooked" them into oil. The reason some of them are thousands of feet deep is they were ancient ocean bottoms.
Fossil fuels
Natural resources such as coal, petroleum (crude oil) and natural gas take thousands of years to form naturally and cannot be replaced as fast as they are being consumed. At present, the main energy source used by humans is non-renewable fossil fuels.
