On February 19, 1863, the first pipeline carrying oil from a well to a refinery was completed. The pipeline connected James Tarr's farm to the refinery in Humboldt, Pennsylvania, 4 kilometers (2.5 miles) away. The pipeline was only 5 centimeters (2 inches) in diameter.Commercial oil wells had only been around for 10 years at the time the pipeline was completed. There was growing interest in using oil for fuel and energy, and new methods were needed to transport oil from where it was extracted to where it was prepared (refined) for use. Oil wells were often in rural areas, while refineries were often in cities, in order to be near workers and customers.Today, oil pipelines are up to .6 meter (2 feet) wide and can move hundreds of liters of oil per second. The longest pipeline in the world is the Druzhba Pipeline, which stretches 4,023 kilometers (2,500 miles) from southeast Russia to Germany.
