Oil production refers to the process of extracting crude oil from the earth. This involves drilling wells into underground reservoirs where oil is trapped in rock formations. Once extracted, the crude oil is transported to refineries for processing. At refineries, the crude oil is transformed into various products, such as gasoline, diesel, and jet fuel. The production of oil is a crucial part of the global energy supply, impacting economies and industries worldwide. Major oil-producing countries include Saudi Arabia, Russia, and the United States.
