This Animated Video Perfectly Explains How Oil Pumpjacks Extract Oil From Underground
Despite being a massive importer of oil from other countries, the United States does also produce oil itself. Statistics suggest most of this oil is used not for fuel but as an ingredient in products.
So where does this oil come from? Most of the oil in the U.S. is extracted in its Southern states.
If you have ever been to this part of the world, you will have surely noticed the very conspicuous oil derrick's or oil wells that are strewn across the country. These odd-looking metal structures pump oil from below the earth and store it on site or send it directly to an oil pipeline.
This great video from Concerning Reality explains in detail how oil derricks work. While using very basic technology, the pumps form an integral part of the oil extraction ecosystem.
They are designed to withstand the harsh conditions of the Southern states and require low maintenance to keep them running basically continuously. Each derrick is designed according to the depth of the well it is drawing from but these machines can 1.5 - 10 gallons of oil per stroke.
The oil removed by the derrick is a mixture of crude oil and water which is then separated depending on the oil's future use. The U.S. exports some of its oil to Canada which is then often imported back in the form of different value-added products.
