Engineered Cable Head-Releasable™
Provides an engineered mechanical weak point combined with the ease of cable-only release
Applications
- Deviated wells
Features and Benefits
- Engineered mechanical weak point for polymer-coated cable applications. This provides the wireline operator the ability to release the wireline cable from the releasable cable head at a predetermined tension
- Suitable for both conventional and polymer-coated (greaseless) cables
- Includes weight bar extension with industry standard 2 to 6-in. Acme connections
Tool Description
The releasable cable head (RCH) offers an engineered mechanical weak point combined with the ease of cable-only release rather than releasing a torpedo or partial downhole assembly. Requiring minimal field training, the RCH is strength-adjusted externally, eliminating the need to rehead.
The RCH is adaptable to inline weight bars with a weight bar extension and is compatible with conventional and greaseless lines.
