  2. Blowout (well drilling) - Wikipedia

    en.wikipedia.org/wiki/Blowout_(well_drilling)

    Blowouts can eject the drill string out of the well, and the force of the escaping fluid can be strong enough to damage the drilling rig. In addition to oil, the output of a well blowout might include natural gas, water, drilling fluid, mud, sand, rocks, and other substances.

  3. Blowout preventer - Wikipedia

    en.wikipedia.org/wiki/Blowout_preventer

    In drilling a typical high-pressure well, drill strings are routed through a blowout preventer stack toward the reservoir of oil and gas. As the well is drilled, drilling fluid , "mud", is fed through the drill string down to the drill bit, "blade", and returns up the wellbore in the ring-shaped void, annulus , between the outside of the drill ...

  4. Relief well - Wikipedia

    en.wikipedia.org/wiki/Relief_well

    In the natural gas and petroleum industry, a relief well is drilled to intersect an oil or gas well that has experienced a blowout.Specialized liquid, such as heavy (dense) drilling mud followed by cement, can then be pumped down the relief well in order to stop the flow from the reservoir in the damaged well.

  5. Cameron ram-type blowout preventer - Wikipedia

    en.wikipedia.org/wiki/Cameron_Ram-type_Blowout...

    The blowout of the Lucas well at the Spindletop field in 1901 lasted for over nine days and spilled over 500,000 US barrels (60,000,000 L; 16,000,000 US gal; 13,000,000 imp gal) of oil. [ 4 ] James Smither Abercrombie (1891–1975), a Texas oil driller, and Harry S. Cameron (1872–1928), who operated a machine shop, formed the Cameron Iron ...

  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.

  7. Glossary of oilfield jargon - Wikipedia

    Spud date: When drilling a new well, the spud date is the day on which the main drill bit begins drilling. For onshore drilling, spudding-in occurs after a wellsite has been prepared and a larger surface hole drilled and cased in preparation for the main drill bit to be used. Subsalt: Refers to oil prospects that lie below a salt layer. [7]

  8. Oil well control - Wikipedia

    en.wikipedia.org/wiki/Oil_well_control

    If the drilling well penetrates the production string of a previously completed well, the formation fluid from the completed well will enter the wellbore of the drilling well, causing a kick. If this occurs at a shallow depth, it is an extremely dangerous situation and could easily result in an uncontrolled blowout with little to no warning of ...

  9. Well control - Wikipedia

    en.wikipedia.org/wiki/Well_control

    During drilling, kicks are usually killed using the Driller's, Engineer's or a hybrid method called Concurrent, while forward circulating. The choice will depend on: the amount and type of kick fluids in the well; the rig's equipment capabilities; the minimum fracture pressure in the open hole; the drilling and operating companies well control ...
