Vigor VTrac™ Wireline Tractor

In recent years, horizontal well drilling and completion technologies have achieved significant maturation. The development of unconventional oil and gas resources, in particular, has been predominantly driven by horizontal drilling, resulting in a surge in the number of wells drilled. Both the lateral lengths and total measured depths of these wells have continually set new records.
In this context, efficiently and reliably delivering logging tools to the target depth-whether in open-hole or cased-hole environments-has become a critical operational challenge. The wireline tractor has emerged as a versatile and efficient solution, providing an alternative to conventional conveyance methods such as drill pipe or coiled tubing. Initially adopted primarily in cased-hole and production wells, its application has increasingly expanded to open-hole logging, reflecting its growing importance in advanced well intervention and evaluation operations.

Oil and Gas Well Logging: Carries various logging tools (such as acoustic, resistivity, gamma ray, caliper, ultrasonic imaging probes, etc.) into oil, gas, or water wells several thousand meters deep to collect information on wellbore temperature, pressure, flow rate, formation parameters, etc., in real-time. This data is used to evaluate reservoir conditions and wellbore integrity.
Production Logging and Diagnostics: Detects production profiles (identifying which zones are producing oil, gas, or water), identifies issues such as paraffin (wax) buildup, scale deposition, corrosion, perforation damage, and deformation in the tubulars, and locates leakage points.
Casing and Tubing Inspection: Conducts high-definition video inspection and ultrasonic wall thickness measurement of downhole casing and tubing to assess their health condition, providing a basis for decision-making regarding workover operations.
Perforation Operations: The crawler can carry perforating guns or small intervention tools to perform precise downhole operations.​
