Tractor Technologies for Well Interventions

Reservoir Descriptions and Dynamics


This afternoon course will take an operational perspective on the state of light intervention technology and how it is changing the way some operators are designing their wells — to be more intervention friendly. The downhole tractor and associated technologies, such as milling, cleaning and hydraulic stroking, have come of age and are being applied in the full range of well deviations, including vertical and inverted wells. Learn how this emerging technology helps with reduce cost, less HSE risk and improved recoveries by enabling more frequent and cost effective interventions.

Learning Level


Course Length

1/2 Day

Why Attend?

Tractor associated technologies have come of age in the last 15 years and are being applied in all ranges of deviation, including vertical and inverted well. Learn how this emerging technology helps in reduced cost, less HSE risk, and improved reservoir recovery.

Who Should Attend

Any personnel who are involved in logging, well completions, HSE, or reservoir recovery in subsea wells will find value in the materials shared regarding this emerging technology.


0.4 CEUs (Continuing Education Units) will be awarded for this 1/2-day course.
