Welltec® Lateral Intervention Tool


Developed for today’s multilateral wellbores, the WellLIT conveys toolstrings into laterals, reliably and efficiently. 

Using a number of sensors the WellLIT identifies where the lateral is and indexes itself so that as it drives forward it enters the lateral. It is fully combinable with 3rd party logging tools so that it can convey the appropriate service to fully understand the previously inaccessible lateral wellbore.


Case highlight

A client in the Middle East needed to perform production logging on a multilateral gas well. The well was drilled in 2013 and included three slim open-hole laterals. In early...

The Welltec Lateral Intervention Tool (WellLIT) is the latest advancement in conveyance and deployment tools from Welltec. It has been designed to address the challenges of intervening in multilateral, maximum reservoir contact wells.

The WellLIT provides access to lateral sections by detecting the window, shifting a steerable joint and directing the toolstring into the window. Combinable with the Well Tractor® as well as 3rd party e-line tools, it provides the operators the capability to enter and evaluate their laterals with a host of e-line technology, illuminating understanding of the well and the reservoir.
