Pump Out Plug With Half Mule

It is used as a tubing plugging device against which pressure is being applied in order to set Hydraulic Set Packers. This is made up with the tail pipe below the Packer to be set. A ball is dropped to run through the tubing and packer up to the ball seat, subsequently the tubing is pressured up. Once the Packer is set, tubing pressure is increased to values shown in the chart below to shear the screws holding the ball seat. The ball and ball seat are blown out of the sub to the bottom of the well. Tubing below the plug should have sufficient ID clearance to permit passage of the ball, ball seat, spring etc. To set a packer number of screws installed in the pump out plug must be compatible with the concerned/rated precise requirement
