Shaker

Definition - What does Shaker mean?

A shaker, in the context of trenchless technology, is a vibrating sieve. It's the primary device on a drilling rig for removing solids from drilling fluids. The liquid portion of drilling fluid is separated from solids that are too large to pass through the wire mesh of the shaker screen. Larger solids remain on the screen to eventually fall from the back of the shaker and are eventually discarded.

Shakers are also referred to as shale shakers.

Trenchlesspedia explains Shaker

The shaker's wire-cloth screen vibrates as drilling fluid flows over it. There are various sizes of screening available and the fineness of the screen is related to the size of the fine particles allowed to mix with the fluid. However, the smaller openings also serve to decrease the flow over or through the screen. This means the drill crew should run the shaker with the finest screen possible but regularly dump the mud from the back of the screen to keep the flow consistent.
