Content: The Permian Basin in Texas, for example, was believed to have run dry in the early 2000s. New technologies, however, have revived the region and the Permian Basin is now the country's leading oil producing region. Extensions — or newly accessible reserves that are attributed to previously existing oil fields — are one way to increase proven reserves. In 2013, extensions contained roughly 4.4 billion barrels of oil across the country, nearly all of which located in the 10 most oil-rich states. Additionally, nearly the entire increase in proven reserves in 2013 was from extensions. As a result of the oil boom in these states, jobs in the mining and logging sector, which includes oil and gas extraction, have increased. In six of these states, employment in the sector grew by more than 60% from 2005 through 2014, higher than the 42% increase in sector employment across the country. GDP growth is another way to measure the vitality of a state's economy. While the U.S. economy grew by 2.2% in 2013, the GDP of seven of the states with the most reserves grew by more than 2.5%, largely driven by the mining industry. In Wyoming, for example, 3.5 percentage points of the state's 5.1% GDP growth came from the mining sector.
