Drilling multi-laterals is becoming a preferred method to increase production from a single wellhead. Coiled tubing's role continues to grow as a well intervention system, but is limited in its capacity for selective entry into multi-lateral completions. Without a practical method to selectively enter multi-lateral completions to perform workovers and stimulation operations, these wells are not achieving their full production potential. A tool has been developed, tested and proven that allows CT to selectively enter each leg of a multi-lateral completion. The tool finds and enters the desired juncture or window and signals the operator at surface that it has done so. The Lateral Entry Guidance System is being used reliably for conventional CT stimulation or cleanout applications, and it has been adapted to run on the end of other specialized tools. This paper will discuss the tools development/testing and case histories of successful operations in the Permian Basin.
