Exit Sub Release Tool


Reduces the risk of having to deploy cutters or complicated and costly wire fishing operations when tools get stuck


Applications

  • Slickline
  • Braided line


Features and Benefits

  • Available in 1-7/8 and 2-1/2 in. OD
  • Integral swivel
  • Suitable for standard and sour service
  • Suitable for up to 15,000 psi (103 MPa) and 165°
  • Reduces the risk of having to deploy wire-cutting devices
  • Reduces the potential for costly, time-consuming, and complicated wire cutting and snapped or cut wire fishing operations
  • Mitigates potential for the dangerous situation of having a tool string permanently stuck across multiple critical well barriers


Tool Description

The Weatherford exit sub release tool (ESRT) is a proactive, electro-mechanical release device that mechanically separates, allowing the wireline, rope socket, and upper section of the ESRT to be retrieved to the surface without hydrostatic pressures, telemetry, or drop bars when tools become stuck downhole.

An industry standard external fish neck on the lower section of the ESRT can then be used for fishing operations to recover the remainder of the toolstring. 

The ESRT reduces the risk of having to deploy cable cutters and complicated and expensive wire and cable fishing operations.
