TCU Tension Compression Unit
The TCU (Tension Compression Unit) is a device designed to accurately measure the load on the wire line at the top of the GeochainTM or GeochainSlimTM string.
This product records during receiver deployment with real time surface read out, providing the seismic engineer with an invaluable tool to detect and prevent receiver hang up.
- TCU 3” Diameter Tool compatible with GeochainTM
- STCU 1 11/16″ Diameter Tool compatible with GeochainSlimTM
- Tension and Compression measure on wireline
- Real time surface read out
- Ready out display with ACQ software.
- High Accuracy
- Operation with hostile well conditions
This new unit has refined pressure compensation capability with the load measurement achieved by means of strain gauges situated within the housing. Mounted directly above the telemetry adapter section (TAS) of the tool string, the TCU measured output voltage is digitised and transmitted by the TAS and displayed at surface within the ACQ software.
All TCU-2 components in contact with borehole fluid are corrosion resistant, and not sensitive to hydrogen embrittlement. The new design has minimised the number of items which need servicing after each deployment (such as O rings). Any items requiring attention can be easily serviced with minimal disassembly.
