Early US oil field. Historical image of early oil wells operating at an oil field in the USA. The vertical structures house drills and pipes used to bore downwards into the ground to bring oil from underground up to the surface. Modern oil drilling in the USA began in the 1850s in West Virginia and Pennsylvania. This led to an oil boom with many workers operating numerous oil wells across the region. At times,more than 100 oil wells would be operating at the same time in a small area. Before this,most of the world's oil had come from Baku in what is now Azerbaijan | |
