1. (obsolete) a worker who places pipe to one side in the derrick. 2. a pneumatic or hydraulic device used to mechanise the rig floor.
Industry:Oil & gas
A fitting, usually divided into two halves, that crew members place inside the master bushing to hold the slips.
Industry:Oil & gas
The portion of the drilling assembly below the drill pipe. It can be very simple, composed of only the bit and drill collars, or it can be very complex and made up of several specialty components.
Industry:Oil & gas
A bridge plug or cement plug placed near the bottom of the hole to shut off a depleted, water-producing, or unproductive zone.
Industry:Oil & gas
A sealing component for a blowout preventer that closes the annular space between the pipe and the blowout preventer or wellhead.
Industry:Oil & gas
1. the pressure at the bottom of a borehole. It is caused by the hydrostatic pressure of the wellbore fluid and, sometimes, by any backpressure held at the surface, as when the well is shut in with blowout preventers. When mud is being circulated, bottomhole pressure is the hydrostatic pressure plus the remaining circulating pressure required to move the mud up the annulus. 2. the pressure in a well at a point opposite the producing formation, as recorded by a bottomhole pressure measuring device.
Industry:Oil & gas
A blowout preventer that uses pipe rams as the closing elements. See pipe ram.
Industry:Oil & gas
A test that measures the reservoir pressure of the well, obtained at a specific depth or at the midpoint of the producing zone. A flowing bottomhole pressure test measures pressure while the well continues to flow; a shut-in bottomhole pressure test measures pressure after the well has been shut in for a specified period of time. See bottomhole pressure.
Industry:Oil & gas
An angled ramp for dragging drill pipe, casing and other materials up to the drilling floor or bringing such equipment down.
Industry:Oil & gas
A portable mast that can be erected as a unit, usually by a tackle that hoists the wireline or by a hydraulic ram. The upper section of a telescoping mast is generally nested (telescoped) inside the lower section of the structure and raised to full height either by the wireline or by a hydraulic system.
