Pump-Off Bit Sub

Description

The Pump-Off Bit Sub is used in conjunction with a bit or mill to complete a workover operation. Upon completing the drilling operation and landing the tubing at surface, a ball is dropped and or pumped to the tool. As a result, pressure is generated causing the locking mechanism to shear and release. The bottom sub then separates and the well is ready for production. Thru Tubing Solutions offers four different styles of bit sub: single flapper, double flapper, ball check and reverse circulating.
