WELLLIT™

WELLTEC® LATERAL INTERVENTION TOOL

Introduction

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.

Overview

The Welltec® Lateral Intervention Tools (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.
