v: to pass from one point throughout a system and back to me starting point. For example, drilling fluid is circulated out of the suction pit, down the drill pipe and drill collars, out the bit, up the annulus, and back to the pits while drilling proceeds.

v: To cycle drilling fluid through the drill string and wellbore, returning to the mud pits. This operation is carried out during drilling and is also used to condition the mud while drilling is suspended.

establishing flow down the tubing or drill pipe and up the annulus. Reverse circulating involves injecting down the annulus and up the drill pipe.

n: the movement of drilling fluid out of the mud pits, down the drill stem, up the annulus, and back to the mud pits. See normal circulation, reverse circulation.

n: The movement of drilling fluid through the flow system on a drilling or workover rig. This circulation starts at the suction pit and goes through the mud pump, drill pipe, bit, annular space in the hole, flowline, fluid pits, and back again to the suction

n: see suction pit.

n: see suction tank, drilling fluid pit.

n: the line that carries a product out of a tank to the suction side of the pumps. Also called the loading line. suction pit n: also called a suction tank, sump pit, or mud suction pit. See suction tank. suction pressure n: the pressure of a gas or fluid entering the suction valve of a compressor.

n: The pipeline between attachment flange at the induction port of pump and suction pit.

n: A mud tank, usually made of steel, connected to the intake of the main rig pumping system. The connection is commonly formed with a centrifugal pump charging the main rig pumps to increase efficiency. Since it is the last tank in the surface mud system, t

a steel tank containing mud, where the input line to the mud pump originates.

n: the mud tank from which mud is picked up by the suction of the mud pumps. Also called a suction pit.

n: The metallic pot used to fill drill fluid.

n: see suction pit.
