The Magnum Frac Sleeve (MFS) is a ball activated shifting sleeve, typically used for diverting fluids to different sections of a well. It can be placed in a vertical or horizontal position. When the shifting ball is on the seat, the area below the MFS is immediately isolated, then applied pressure shifts the ball, ball seat, and inner sleeve down into the open position, thereby diverting fluid out the side ports. By utilizing different ball seat sizes and shifting ball, up to 11 DAFPS tools can be run in an assembly hookup.
