Monitoring and maintaining safe cable tension downhole are essential to preventing pumpoff and reducing the risk of fishing operations during pumpdown in deviated and horizontal wells. The GR Energy Services wireline cable tension monitoring tool, incorporating SMART Sens™ technology, provides real-time cable tension and compression measurements to minimize risk and reduce operating costs.
Surface cable tension measurements do not account for the effects of friction in highly deviated sections, which makes it difficult to maintain safe cable tension. If the cable tension is too great, pumpoff can occur when the weak-point limit is exceeded. If the cable tension is too low, the tool string may begin to stick or slip, causing erratic tool string motion that increases the risk of cable damage or pumpoff.
