n: the liquid seal that reduces slippage between moving parts of a meter.

n: the volume of liquid at a given flow rate that passes through a meter without being measured.

related to the amount of fluid that slips by a meter without being accurately recorded.

n: a low-dip angle (nearly horizontal) reverse fault along which a large displacement has occurred. Some overthrusts, such as many of those in the Rocky Mountain Overthrust Belt, represent slippages of many miles.

n: a method of artificial lift that utilizes a plunger that travels up and down inside the tubing. Internally, the plunger contains a bypass valve that is opened when it hits the top of the tubing and closed when it hits the bottom. The plungers fit with the tubing reduces liquid slippage back through the well fluid and the gas that is propelling it. Plunger lift is used in less than 1 percent of all artificially produced wells. It is particularly applicable, however, in high gas-liquid ratio oilwells or in gas wells with low bonom- hole pressure and low productivity.

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.
