SMART SensTM Tension Monitoring Tool

SMART SensTM Tension Monitoring Tool
Prevent Pump-Off, Stuck Tools and Expensive Fishing Operations
Maintaining safe cable tension downhole is challenging in lateral wells because
surface cable tension measurements do not account for friction effects in the highly
deviated sections of the well. The SMART SensTM cable tension monitoring device is
specifically designed to reduce the risk of fishing operations during pump-down in
extended lateral wells.
If the cable tension is too high: pump-off can occur when the weak-point limit
is exceeded.
If the cable tension is too low: the tool string may begin to stick/slip, with the
erratic tool string motion increasing the risk of cable damage or pump off.
The SMART SensTM provides a real time cable tension and compression
measurement which gives the operator increased control.
