The plug catcher is used in well completion operations when the zone isolation plugs are being milled out to allow the well to be produced to surface. As the plugs are being milled there is a constant circulation of fluid in order to bring the milled parts to surface. This circulation is passed through screens inside of the plug catcher which allows fluid and sand to pass but retains the larger plug parts. This eliminates plugging of the downstream chokes and flowlines.
The plug catcher has dual screens in parallel which can be isolated from each other. This allows the user to clean out screens on the fly while maintaining circulation through the other side.
