An Innovative New Combination of Coiled Tubing Tools Which Enables Multiple Re-Entry into Open Hole Laterals Without Any Pre-Placed Datum Devices in the Completion During the Well Construction Phase

This paper summarises the evolution of coiled tubing tools from the simple jetting nozzle<br>through to the highly advanced multi-function multi shot tools currently in use today. The paper<br>goes on to illustrate an innovative method devised for entering open hole laterals as a direct<br>response to demand for cost effective well maintenance solutions against a backdrop of low oil<br>prices. The tool illustrated is an evolution of existing knowledge on re-entry technology<br>combined with the best features of current multi-function coiled tubing manipulation tools. The<br>new solution allows repeated acces to lateral junctions without the need for special completion<br>components during the well construction phase.
