n: a conducting ring that gives current to or receives current from the brushes in a generator or motor.

n: a single part of all the parts, or segments, that make up the slips. See also slips.

n: see slip.

a wireline set plug with slips and seals much like a small packer.

n: a procedure to determine whether the slips inserts (dies) are unifOrn1ly contacting the wall of the drill pipe. Paper is wrapped around the pipe and the slips are set. The paper is then unwrapped from die pipe and the pattern the slips made on the paper is examined. If uniform contact is not shown, the slips inserts are replaced or the insert bowl is repaired or replaced.

n: 1. the rate at which drilled solids tend to settle in the borehole as a well is being drilled. 2. difference between the annular velocity of the fluid and the rate at which a cutting is removed from the hole.

n: the difference between the annular velocity of the fluid and the rate at which a cutting is removed from the hole.

n: a procedure to ensure that the drilling line wears evenly throughout its life. After a specified number of ton-miles (mega joules) of use, the line is slipped-i.e., the traveling block is suspended in the derrick or propped on the rig floor so that it cannot move, the dead- line anchor bolts are loosened, and the drilling line is spooled onto the drawworks drum. Enough line is slipped to change the major points of wear on the line, such as where it passes through the sheaves. To pre- vent excess line from accumulating on the drawworks drum, the worn line is cut off and discarded.

n: liquid that slips between the blade or lobed impeller of a displacement meter and the meter housing instead of being captured between the two blades or impellers and being measured.

where two phases travel in the same direction but at different velocities.

n: The reverse and resect process to drill wire rope when drilling.
