Demands of Multi-Lateral Well Junctions are shifting from successful shallow wells to deeper and more functional window applications. Reliable window exit, reduced trips and improved debris management while drilling have provided the confidence to take this step. Completion and Production opportunities are the focus areas. Reliable and low cost re-entry capability both through tubing and through casing is demanded. Fluid isolation and shut-off during drilling, production, injection, stimulation and production logging operations are being developed. Innovative multiple lateral completions equipment is required to provide a cost effective solution. These tools and techniques are presented.
