Screen

Definition - What does Screen mean?

A screen, in trenchless technology, is a woven wire cloth panel that is similar in form to a screen window covering. A screen is used as a filter in a shale shaker. It's the element that separates fine and extra fine particles from the drilling fluid. In trenchless construction, it is vital that the drilling fluid be kept as fluid and clean as possible.


Trenchlesspedia explains Screen

During a drilling operation, it is important to remove fine particles from the drilling fluid. The shaker's wire-cloth screen vibrates as drilling fluid flows over it. While smaller openings in the screen means fewer fine particles, it also means a decrease in flow through the screen. This means the drill crew should run the shaker with the finest screen possible and dump the mud from the back of the screen regularly. Shakers are also known as shale shakers.
