Ball-Drop Frac Plug Configuration


After the ProDrill Express ball-drop frac plug is set, the ID remains open, allowing work to continue above. A ball is then dropped from the surface and pumped down until it seats on the tool. Once the ball is seated, the operator can pressure up against the frac plug. The ball can also be run in place, between the shear sleeve adapter and mandrel, allowing it to be used as a flowback plug without having to drop the ball from surface.
