Rotating Ball Seat Sub

Rotating Ball Seat Sub eliminates the extreme impact of shearing out a ball seat at the bottom of the liner which could possibly breakdown sensitive formations.

• Full-bore clearance after ball seat shears
• High-inclination wells
• Design that ensures that the ball is dislodged as the ball seat shears.
• Design that ensures that the ball seat is completely tripped and retained in full-bore open position
• Variable shear-pressure settings for liner systems consisting of numerous hydraulic actuating parts

• Minimizes risk of ball-seating failure in horizontal sections
• Saves operation time in long liners because ball does not have to reach liner toe
• Reduces risk of fracturing formation because of sharp rise in equivalent circulating density (ECDs) when conventional liner toe ball seats shear.
