Reliable tool functionality for subsequent operations.

The REGEN™ Dual Ball Seat Sub (DBSS) uses two independent and redundant ball seats that can be configured for various ball and shear pressures, allowing for the operation of a range of hydraulic set tools.

The appropriate ball is pumped down and lands in the seat, allowing pressure to build up to function any hydraulic tool, after which the ball can be expelled, permitting full circulation to be regained. An integral baffle plate retains the balls and ball seats in the DBSS.

The DBSS allows the operator to reliably function hydraulic tools and still regain full circulation for subsequent operations.
