    • How is oil extracted?
    • Petroleum is mostly recovered from oil drilling. Seismic surveys and other methods are used to locate oil reservoirs. Oil rigs and oil platforms are used to drill long holes into the earth to create an oil well and extract petroleum. After extraction, oil is refined to make gasoline and other products such as tires and refrigerators.
    • How does oil flow through a geologic formation?
    • Oil may flow to the earth's surface from natural pressure in the rock formation, or it may have to be forced out of the ground and up through a well. The type of geologic formation where the oil is located determines the technologies used to start the flow of oil and natural gas from the reservoir or resource-bearing rock into the wells.
    • Where does oil come from?
    • Petroleum deposits, which are naturally mixed with water and gas, lie thousands of feet below the earth’s surface in layers of porous rock, typically sandstone or limestone. (Contrary to what you might imagine, drilling for oil is more like sucking oil from a sponge with a straw than from a giant pool of liquid.)
    • How does oil flow through a rock layer?
    • Steam, water, or carbon dioxide (CO 2) can also be injected into a rock layer to help oil flow more easily into production wells. After the oil has been collected from wells in a production field, pipelines, barges, trains, or trucks transport the oil to refineries or to ports for shipment on oil tankers to other countries.
