The current wave of automation is sometimes described as the fourth industrial revolution. And almost every industry is affected, including oil and gas. Almost 40 percent of oil and gas workers are in Texas. With the price of crude oil at $70 a barrel, there’s a boom — but not in hiring. Job numbers haven’t gone up as much as some observers expected. Automation is partly to blame, but the industry is bringing in other technologies to stay ahead of the game as well.
