Description

Our i-Seat is a field-proven ball seat sub that is installed as part of the completion string. The simple, robust design can be installed anywhere future isolation points are required. When isolation is desired, a dissolvable ball is dropped from surface and lands in the i-Seat. Once seated, pressure can be applied to test casing integrity, set hydraulically activated packers, or activate other completion tools above the i-Seat. After a predetermined time frame, the ball will dissolve, allowing production or injection to begin without well intervention.
