Achieving successful zonal isolation is critical to install smart completion tools. Currently, cementing and mechanical packers are the only conventional methods used in Saudi fields to provide zonal isolation. However, these convential techniques are difficult to operate and result in reduced inner casing string diameter.Another method to provide zonal isolation for smart completion tools and to complete them in single stage is to use a rubber elastomer bonded onto a base pipe. The rubber swells in oil and provides a seal between the base pipe and the open hole. This paper will outline the step-by-step qualification testing that was carried out by SaudiAramco facilities in an attempt to improve zonal isolation for smart completions.
