Schlumberger’s BroadBand Sequence fracturing technique enables sequential stimulation of perforation clusters in wells drilled in unconventional reservoirs. This new technique sequentially isolates fractures at the wellbore to ensure every cluster in each zone is fractured, resulting in greater production and completion efficiency when compared with conventional methods. Developed using a composite fluid comprising a proprietary blend of degradable fibers and multimodal particles, the BroadBand Sequence technique is suited for use in new wells and in recompletions. This technique is particularly suitable for refracturing operations, given its ability to promote temporary cluster isolation without the aid of mechanical devices such as bridge plugs. BroadBand has delivered robust and consistent performance in more than 500 operations conducted to date in several unconventional plays including the Eagle Ford, Haynesville, Woodford, Spraberry, and Bakken shales. In south Texas, BroadBand has enabled users to increase production from new completions in unconventional reservoirs by more than 20%. It has also reduced well completion time by up to 46% in plug-and-perforation operations by stimulating longer intervals compared with conventional methods. In addition, this technology was applied to a well in south Texas for a refracturing operation, which resulted in double the production with a fourfold increase in flowing pressure.
