Well Tractor®

The original tractor with 25 years of experience

World class conveyance solutions

The Well Tractor was regarded as a revolution in the industry when it was introduced to the market in the 1990's.

It enables operators to extend the reach of traditional e-line deployment into highly deviated and horizontal wells, making it one of the most cost-effective and successful applications for deployment in well interventions.

Case highlight

In late 2017, a Russian operator needed production logging (PLT) data from a well with a long lateral of more than 16,000 ft (4,850 m). Because of the length of the...

Overview

An e-line deployed, self-propelled, robotic device, it overcomes the limitations of traditional e-line operations in highly deviated wells by driving the tools to the toe of the wellbore.

The Well Tractor can carry out operations throughout the entire length of the wellbore regardless of the deviation and extension of the well. In open hole wells the Well Tractor can apply the force required to push large tool strings as well as navigate past washouts.
