Long before the first commercial oil wells appeared in North America, Chinese engineers had already mastered the art of drilling deep into the earth. In the salt-producing region of Zigong in China's Sichuan Province, workers were sinking wells hundreds of meters deep using techniques that would not become common in the West until many centuries later. These remarkable salt wells not only transformed the economy of inland China but also helped inspire the drilling methods that fuelled the 19th-century oil boom in the United States.
