Glossary Of Oilfield Jargon
Oilfield terminology refers to the jargon used by those working in fields within and related to the upstream segment of the petroleum industry. It includes words and phrases describing professions, equipment, and procedures specific to the industry. It may also include slang terms used by oilfield workers to describe the same. Examples *Bell nipple: An enlarged pipe at the top of a casing string that serves as a funnel to guide drilling tools into the top of the well. *Big bear: A big bear is a hitch (see hitch) that lasts a minimum of 50 straight days. *Black Leg : Joints of pipe racked back in the derrick. * Blowout: A sudden, uncontrolled release of underground pressure from the well. *BOP (Blowout preventer): Pronounced "B-O-P", not "bop", is a mechanical device connected to the wellhead to control and prevent blowouts. *Catwalk: Elevated platform used for sliding pipe up to the rig floor. *Chainhand (also motorman): An experienced laborer capable of maintaining most part ...

Jargon
Jargon is the specialized terminology associated with a particular field or area of activity. Jargon is normally employed in a particular communicative context and may not be well understood outside that context. The context is usually a particular occupation (that is, a certain trade, profession, vernacular or academic field), but any ingroup can have jargon. The main trait that distinguishes jargon from the rest of a language is special vocabulary—including some words specific to it and often different senses or meanings of words, that outgroups would tend to take in another sense—therefore misunderstanding that communication attempt. Jargon is sometimes understood as a form of technical slang and then distinguished from the official terminology used in a particular field of activity. The terms ''jargon'', ''slang,'' and '' argot'' are not consistently differentiated in the literature; different authors interpret these concepts in varying ways. According to one definit ...

Top Drive
A top drive is a mechanical device on a drilling rig that provides clockwise torque to the drill string to drill a borehole. It is an alternative to the rotary table and kelly drive. It is located at the swivel's place below the traveling block and moves vertically up and down the derrick. Benefits The top drive allows the drilling rig to drill the longer section of a stand of drill pipe in one operation. A rotary table type rig can only drill (single drill pipe) sections of drill pipe whereas a top drive can drill stands (double and triple drill pipe respectively, a triple being three joints of drillpipe screwed together), depending on the drilling rig size. Handling longer sections of drill pipe enables a drilling rig to make greater daily progress because up to can be drilled at a time, thus requiring fewer "connections" to add another of drill pipe. Another advantage of top drive systems is time efficiency. When the bit progresses under a kelly drive, the entire string ...

Piston Corer
A piston is a component of reciprocating engines, reciprocating pumps, gas compressors, hydraulic cylinders and pneumatic cylinders, among other similar mechanisms. It is the moving component that is contained by a cylinder and is made gas-tight by piston rings. In an engine, its purpose is to transfer force from expanding gas in the cylinder to the crankshaft via a piston rod and/or connecting rod. In a pump, the function is reversed and force is transferred from the crankshaft to the piston for the purpose of compressing or ejecting the fluid in the cylinder. In some engines, the piston also acts as a valve by covering and uncovering ports in the cylinder. __TOC__ Piston engines Internal combustion engines An internal combustion engine is acted upon by the pressure of the expanding combustion gases in the combustion chamber space at the top of the cylinder. This force then acts downwards through the connecting rod and onto the crankshaft. The connecting rod is attache ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pigging
In pipeline transportation, pigging is the practice of using pipeline inspection gauges or gadgets, devices generally referred to as pigs or scrapers, to perform various maintenance operations. This is done without stopping the flow of the product in the pipeline. These operations include but are not limited to cleaning and inspecting the pipeline. This is accomplished by inserting the pig into a "pig launcher" (or "launching station") — an oversized section in the pipeline, reducing to the normal diameter. The launching station is then closed and the pressure-driven flow of the product in the pipeline is used to push the pig along the pipe until it reaches the receiving trap — the "pig catcher" (or "receiving station"). Applications Pigging is used to clean large diameter pipelines in the oil industry. Today, however, the use of smaller diameter pigging systems is now increasing in many continuous and batch process plants as plant operators search for incre ...

Petroleum Play
In geology, a petroleum play, or simply a play, is a group of oil fields or prospects in the same region that are controlled by the same set of geological circumstances. The term is widely used in the realm of exploitation of hydrocarbon-based resources. The play cycle normally exhibits the following steps: # initial observations of a possible oil reserve # testing and adjustments to initial estimates of extraction # high success in locating and extracting oil from a reserve # lower success as the reserve is depleted # continued decrease in further exploration of the region A particular stratigraphic or structural geologic setting is also often known as a ''play.'' For example, in a relatively unexplored area (such as the Falkland Islands) one might speak of the "Paleozoic play" to refer to the potential oil reserves that might be found within Paleozoic strata. In a well-explored basin such as the Gulf of Mexico, explorers refer to the "Wilcox play" or the "Norphlet play" to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moon Pool A moon pool is a feature of marine drilling platforms, drillships and diving support vessels, some marine research and underwater exploration or research vessels, and underwater habitats, in which it is also known as a wet porch. It is an opening in the floor or base of the hull, platform, or chamber giving access to the water below, allowing technicians or researchers to lower tools and instruments into the sea. It provides shelter and protection so that even if the ship is in high seas or surrounded by |
