  2. Extraction of petroleum - Wikipedia

    en.wikipedia.org/wiki/Extraction_of_petroleum

    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. Extraction of petroleum can be dangerous and have led to oil spills. [1]

  3. Enhanced oil recovery - Wikipedia

    en.wikipedia.org/wiki/Enhanced_oil_recovery

    Enhanced oil recovery (abbreviated EOR), also called tertiary recovery, is the extraction of crude oil from an oil field that cannot be extracted otherwise. Whereas primary and secondary recovery techniques rely on the pressure differential between the surface and the underground well, enhanced oil recovery functions by altering the physical or ...

  4. Petroleum refining processes - Wikipedia

    en.wikipedia.org/wiki/Petroleum_refining_processes

    Petroleum refinery in Anacortes, Washington, United States. Petroleum refining processes are the chemical engineering processes and other facilities used in petroleum refineries (also referred to as oil refineries) to transform crude oil into useful products such as liquefied petroleum gas (LPG), gasoline or petrol, kerosene, jet fuel, diesel oil and fuel oils.

  5. Heavy oil production - Wikipedia

    en.wikipedia.org/wiki/Heavy_oil_production

    Oil recovery involves three stages of extraction: primary, secondary and tertiary. Since mobility is a ratio of effective permeability and phase viscosity, the productivity of a well is directly proportional to the product of layer thickness of the reservoir rock and mobility. [15] [16]

  6. Carbon dioxide flooding - Wikipedia

    en.wikipedia.org/wiki/Carbon_dioxide_flooding

    In some cases, carbon dioxide (CO 2) flooding may be an ideal tertiary recovery method to recover more of the recoverable oil than could be produced using secondary oil recovery methods. Because of its special properties, CO 2 improves oil recovery by lowering interfacial tension , swelling the oil, reducing viscosity of the oil, and by ...

  7. Microbial enhanced oil recovery - Wikipedia

    en.wikipedia.org/wiki/Microbial_enhanced_oil...

    Microbial Enhanced Oil Recovery (MEOR) is a biological-based technology involving the manipulation of functions or structures within microbial environments present in oil reservoirs. The primary objective of MEOR is to improve the extraction of oil confined within porous media, while boosting economic benefits.

  8. Petroleum industry - Wikipedia

    en.wikipedia.org/wiki/Petroleum_industry

    Upstream regards exploration and extraction of crude oil, midstream encompasses transportation and storage of crude, and downstream concerns refining crude oil into various end products. Petroleum is vital to many industries, and is necessary for the maintenance of industrial civilization in its current configuration, making it a critical ...

  9. Oil refinery - Wikipedia

    en.wikipedia.org/wiki/Oil_refinery

    An oil refinery or petroleum refinery is an industrial process plant where petroleum (crude oil) is transformed and refined into products such as gasoline (petrol), diesel fuel, asphalt base, fuel oils, heating oil, kerosene, liquefied petroleum gas and petroleum naphtha.
