Important Terms to Know About Oil Field Equipment
These important terms could help you better understand the types of equipment commonly and techniques used in oil fields:
Offshore Drilling: Drilling that takes place underwater, often several miles off of a coastline. Offshore drilling gives the oil industry access to underwater fields, but it also increases the risks of environmental damage when accidents occur. Equipment malfunctions at offshore drilling fields have been the cause of most oil-related environmental tragedies in North America.
Drilling Fluid: A liquid mixture that forces cuttings out of the wellbore. Bringing cuttings to the surface allows drills to penetrate deeper into the ground without getting damaged or stuck. The drilling fluid, also known as circulating fluid, is often made from a combination of water, clay, and chemicals.
Air Drilling: A drilling method that uses compressed air instead of circulating fluids to remove cuttings from the wellbore. Air drilling works well in most circulations. If the drill encounters underground water, however, air drilling because much less efficient.
Wellbore: The hole created by drilling a bit below the surface. Open wellbores do not have casings that offer support. Some wellbores have areas with casings and areas without casings.
Oil Reserve: The total known amount of oil in a reservoir. It is also referred to as "oil in place." An oil reserve can contain producible and non-producible oil. Oil companies often spend a significant amount of time and money searching for oil reserves that contain large amounts of crude. They can then pump out the oil and refine it into gasoline, petrol, out other types of products made from fossil fuels.
