A client needed to isolate a wet shale / sand zone, shallow of the reservoir with a NACE compliant Barrier & ¼” DTS feed thru. It was imperative that a barrier...
WAB® with Control Line Feed Through
Through WAB communication with downhole devices
Through continued evolution of product design, we can now offer the WAB (Welltec® Annular Barrier) with the added feature of multiple Control Line Feed Through. This value adding feature now allows for the placement of hydraulically and electrically controlled downhole devices below or between WAB’s set within open hole or cased hole.
Incorporation of the WAB with Control Line Feed Through, coupled with hydraulically controlled ICV & TEC DHPG, will significantly reduce CAPEX, time and complexity within a multi zone intelligent lower completions by removing the need for cementing & perforated a liner by providing the open hole isolation with the WAB with Control Line Feed Through.
