High temperature logging with DC Well Tractor®

The toolstring was run in hole with the Well Tractor and logging tool to the kick-off point at about 11,581 ft (3,530m), at which point the operator began pumping well fluid at approximately one bpm to help keep the temperature within limits. The Well Tractor was engaged and conveyed the toolstring ~1,000 ft (~300m) further before activating the ultrasonic tool for the caliper and bond information required around the perforations.
Well Tractor and DC electronics handled the high temperatures with no complications, proving its applicability to extreme environments.
The Well Tractor was regarded as a revolution in the industry when it was introduced in the 1990’s. It enables operators to extend the reach of traditional e-line deployment into highly deviated and horizontal wells.
