Short Description
2-3/8" Wireline Entry Guide, Shear-out ball seat 2-3/8" Wireline Entry Guide, Shear-out ball seat


The Bakerline™ series wireline entry guide is designed to be run on the bottom of the tubing string, aiding in the re-entry of wireline tools into the tubing. When used with the shear-out ball seat, a hydraulic packer can be set without using anadditional plugging device.

To pressurize the tubing string, the wireline entry guide with ball seat is installed on the bottom end of the tubing, the completion is run to depth, then the ball is dropped from surface and fluid is pumped. 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 is pumped out, the sub allows unrestricted access from the tubing into the casing below the tubing string. This product is available in L80 material, with 4.7ppf, 2-3/8” EU 8RD threads.

The shear-out ball-seat sub can be furnished in a box x-pin configuration for applications where it is necessary to run additional tubing or completion equipment below the shear-out ball-seat sub. When the ball and ball seat are used, they are expelled during operation, so it is necessary to ensure they will safely pass through all equipment located below them.
