There are many ways to become a billionaire: you can run a hedge fund, launch a tech startup, be a real estate developer and even win the genetic lottery and inherit your fortune. Basically, if you choose the right career and work very very hard, you, too, can become one of the world's wealthiest people. That's what these men did. They made their fortunes in black gold, Texas tea, or, in other words, the oil and gas industry. Of the 565 billionaires in the United States, more than a dozen of them made their money in oil and gas. Three of the 100 richest Americans are from the oil and gas industry. These tycoons are among the richest people in Texas. Many of the oil and gas billionaires live in Houston, while in Dallas, 10 of the city's 22 billionaires made their fortunes in the oil industry. The average net worth of these Texas oil and gas billionaires is $4.1 billion.
