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.

The average Texas oil well is 900 feet deeper again – but this is quite literally just scratching the surface. Hydraulic fracturing reaches depths ranging from 5,000 feet to 20,000 feet.

In September 2009, the rig drilled the deepest oil well in history at a vertical depth of 35,050 ft (10,683 m) and measured depth of 35,055 ft (10,685 m) in the Tiber Oil Field at Keathley Canyon block 102, approximately 250 miles (400 km) southeast of Houston, in 4,132 feet (1,259 m) of water.

Despite the earlier negative associations with oil among many ranchers and farmers, demand for kerosene and other petroleum derivatives drove oil prospecting in Texas after the American Civil War at known oil-producing springs and accidental finds while drilling for water.

Here are seven of the world’s most important oil cities.

• Aberdeen.
• Houston. The capital of the U.S. oil industry, Houston has seen unprecedented economic growth as high oil prices fuelled the shale oil and gas boom.
• Calgary.
• Rio de Janeiro.
• Williston.
• Stavanger.
• Abu Dhabi.

Originally Answered: Why is there so much oil in Saudi Arabia? because millions of years ago, a lot of marine life died, was deposited on the ocean floor, and over time was compressed into oil and preserved very well in that area. Beyond that, the oil is very high quality, so they export as much as they can.

However, the IMF says that, without more significant reforms than those already announced, the financial wealth of Saudi Arabia, Kuwait, the UAE and others could be depleted by 2034.
