America’s 10 Richest Oil Barons

The Koch brothers sit atop a new list of the 10 wealthiest individuals in America’s oil and gas sector with a combined net worth of $83 billion, according to a new report from consulting company Wealth-X.

The list includes billionaires from Texas, Kansas, Oklahoma, and Colorado. “It is interesting to note that oil-driven wealth in North Dakota is creating millionaires, but we have yet to see a significant increase in the ultra-wealthy in that area,” Wealth-X president David Friedman said in a statement.

Charles Koch, chairman and chief executive of Koch Industries, and David Koch, its executive vice president, are the majority owners of the Wichita-based company, which is involved in the manufacturing, refining and distribution of petroleum, chemicals, polymer and other materials. The brothers each own 42 percent of Koch Industries, which was founded by their father in 1940, and they control more than half the combined net worth of the top 10 billionaires on the list.

Still, the Koch brothers’ wealth pales in comparison to Bill Gates, the richest man in America, who was worth $72.6 billion at the end of last year.

The ranks of billionaires worldwide have swelled nearly 60 percent since the end of the U.S. recession in 2009, and their total wealth increased 5.3 percent in the past year, according to the Wealth-X and UBS Billionaire Census.

The number of billionaires is expected to continue to climb, too. Wealth-X predicts that by 2020, the global billionaire population (currently 2,170) will increase by 1,700 individuals to nearly 3,900 people.
