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

gas removed from the mud at the flowline by mechanical means.

n: The large-diameter metal pipe that connects the bell nipple under the rotary table to the possum belly at the mud tanks. The flowline is simply an inclined, gravity-flow conduit to direct mud coming out the top of the wellbore to the mud surface-treating

the flow connection from the wellhead to the separation facility, pipeline or storage unit.

the pipe connection between the well and the separators or tank battery.

n: a chemical feed pump that injects chemical reagents into a flowline system to treat emulsions at a rate proportional to that of the flow of the well fluid. Operating power may come from electric motors or from linkage with the walking beam of a pumping well.

n: a trough or pipe that is placed between the surface connections at the wellbore and the shale shaker and through which drilling mud flows on its return to the surface from the hole. Also called flow line.

n: a though or pipe through which the mud being circulate up the annulus is transferred from the top of wellbore to the shale shakers (q.v.).sometimes calledflowline.

n pi: the mud, cuttings, and so forth, that circulate up the hole to the surface.

n: Mud that comes back to the surface and exits through the flowline after being pumped down the drillpipe. Lost returns is the situation in which some or all of the Mud does not come back to the surface, which indicates that mud is being lost into weak, f

fluids and solids flowing out of a well during circulating.
