  2. Oil well - Wikipedia

    en.wikipedia.org/wiki/Oil_well

    An oil well is a drillhole boring in Earth that is designed to bring petroleum oil hydrocarbons to the surface. Usually some natural gas is released as associated petroleum gas along with the oil. A well that is designed to produce only gas may be termed a gas well. Wells are created by drilling down into an oil or gas reserve and if necessary ...

  3. Extraction of petroleum - Wikipedia

    en.wikipedia.org/wiki/Extraction_of_petroleum

    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.

  4. Directional drilling - Wikipedia

    en.wikipedia.org/wiki/Directional_drilling

    Because gas floats above oil, the thin red contour line marks the gas/oil contact zone. Directional drilling would be used to target the gas and oil reservoir. Directional drilling (or slant drilling) is the practice of drilling non-vertical bores. It can be broken down into four main groups: oilfield directional drilling, utility installation ...

  5. Offshore drilling - Wikipedia

    en.wikipedia.org/wiki/Offshore_drilling

    Offshore drilling. Holstein, an oil drilling platform at Green Canyon in the Gulf of Mexico, approximately 100 miles from land. Offshore drilling is a mechanical process where a wellbore is drilled below the seabed. It is typically carried out in order to explore for and subsequently extract petroleum that lies in rock formations beneath the ...

  6. Well drilling - Wikipedia

    en.wikipedia.org/wiki/Well_drilling

    Well drilling is the process of drilling a hole in the ground for the extraction of a natural resource such as ground water, brine, natural gas, or petroleum, for the injection of a fluid from surface to a subsurface reservoir or for subsurface formations evaluation or monitoring. Drilling for the exploration of the nature of the material ...

  7. Drilling rig - Wikipedia

    en.wikipedia.org/wiki/Drilling_rig

    A drilling rig is an integrated system that drills wells, such as oil or water wells, or holes for piling and other construction purposes, into the earth's subsurface. Drilling rigs can be massive structures housing equipment used to drill water wells, oil wells, or natural gas extraction wells, or they can be small enough to be moved manually ...

  8. List of components of oil drilling rigs - Wikipedia

    en.wikipedia.org/wiki/List_of_components_of_oil...

    Mud pump (#4) is a reciprocal type of pump used to circulate drilling fluid through the system. Mud tank (#1) is often called mud pits and stores drilling fluid until it is required down the wellbore. Setback (#17) is a part of the drill floor (#21) where the stands of drill pipe are stood upright. It is typically made of a metal frame ...

  9. Oil well control - Wikipedia

    en.wikipedia.org/wiki/Oil_well_control

    Oil well control is the management of the dangerous effects caused by the unexpected release of formation fluid, such as natural gas and/or crude oil, upon surface equipment of oil or gas drilling rigs and escaping into the atmosphere. Technically, oil well control involves preventing the formation gas or fluid (hydrocarbons), usually referred ...
