SHEAR-OUT BALL SEAT SUB
Product No. BI 799-27
WIRELINE ENTRY GUIDE WITH SHEAR-OUT BALL SEAT
Product NO. BI 469-21
The Shear-Out Ball Seat Sub and the Wireline Entry Guide with Shear-Out Ball Seat are installed on the bottom end of the tubing to allow the tubing string to be pressured. When the differential pressure at the tool reaches a predetermined value the ball and seat are pumped out of the tool. After the Ball Seat has been pumped out, these subs allow unrestricted access from the tubing into the casing below the tubing string.
These products are available in a variety of configurations. The tool illustrated here offers both a reentry guide to simplify wireline operations (Prod. No. BI 469-21 only) as well as a optional conical guide to facilitate easy entry when running the tubing through the top of a liner or into a seal bore packer. Other options include a solid pump-out plug and expendable check valves. The Shear-Out Ball Sub (Prod. No. BI 799-27) can also be furnished in a box x pin configuration for those applications where it is necessary to run additional tubing or completion equipment below the Shear-Out Ball Seat Sub.
Caution : Since each of these tools expend a Ball and Ball Seat during their operation, it is necessary to ensure those parts will safely pass through all equipment which is located below them.
