sloughing particles into the well.

n: a quantity of fluid injected into a reservoir to accomplish a specific purpose, such as chemical displacement of oil.

n: a heave,viscous quantity of mud that is pump into the drill string prior to pulling out.the slug will cause the level of fluid in the pipe to fall,thus eliminating the loss of mud on the rig floor when connections are broken.

a volume of gas or liquids that moves through the well and the production facility. A well that flows alternating volumes of water and gas is slugging.

n: A multiphase-fluid flow regime characterized by a series of liquid plugs (slugs) separated by a relatively large gas pockets. In vertical flow, the bubble is an axially symmetrical bullet shape that occupies almost the entire cross-sectional area of the t

flow of distinct volumes of gas and liquid, often signaling unstable behavior.

n: a relatively small separate tank or a small part of a larger tank that holds a small amount of mud for a special purpose. For example, it may hold a small quantity of heavy mud that will be used to slug the drill string. That is, the slug will be pumped into the string to keep mud from falling onto the rig floor when a drill pipe joint is broken out during a trip.

v: to pump a quantity of heavy mud into the drill pipe. Before hoisting drill pipe, it is desirable (if possible) to pump into its top section a quantity of heavy mud (a slug) that causes the level of the fluid to remain below the rig floor so that the crew members and the rig floor are not contaminated with the fluid when stands are broken out.

v: a procedure before pulling the drill pipe whereby a small quantity of heavy mud is pumped into the top section to cause an unbalanced column. As the pipe is pulled, the heavier column in the drill pipe will fall, thus keeping the inside of drill pipe dry

n: a special chemical demulsifier that is often added to emulsion samples to determine the total amount of sediment and water in the samples. Also called knockout drops.

n: Bumping a section of weighted drill fluid into the bottom hole for preventing blowout .

n: Bumping a section of weighted drill fluid into the well head for preventing blowout .

n: a procedure before pulling the drill pipe whereby a small quantity of heavy mud is pumped into the top section to cause an unbalanced column. As the pipe is pulled, the heavier column in the drill pipe will fall, thus keeping the inside of drill pipe dry

n: A kind of borehole collapse .clumpy or pieces of rock fall in the hole .
