• North American shale projects have seen a significant increase in implementation of multistage fracturing as a completion method. Though perforating the extended section of horizontal wells initially proved challenging, advances in technology and improvement in completion techniques ultimately yielded better stimulation of the entire horizontal interval.

    The adoption of multistage fracturing in North American shale has now led to additional interest in other regions. In a landmark project in Saudi Arabia, one operator recognized the potential of our i-Frac™ ball-drop activated sliding-sleeve system and Burst Port System (BPS™) to overcome the limitations of typical wireline and coiled tubing operations. 

    The operator chose the two systems to be used in the longest long-string horizontal well ever completed in Saudi Arabia. The extended-reach well was cemented, completed, and hydraulically fractured in zones that were previously inaccessible by coiled tubing or wireline and drilled to land at approximately 18,717-ft (5,704-m) measured depth.
