Schlumberger introduces fracturing technique for unconventionals
HOUSTON -- Schlumberger has announced the introduction of the BroadBand Sequence fracturing technique, which 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 compared to conventional methods.
Developed using a composite fluid, comprising a proprietary blend of degradable fibers and multimodal particles, the technique is suited for use in new wells and in recompletions. This technique is particularly suitable for re-fracturing operations, given its ability to promote temporary cluster isolation, without the aid of mechanical devices such as bridge plugs.
This fracturing technique has been delivered in more than 500 operations in several unconventional plays, including the Eagle Ford, Haynesville, Woodford, Spraberry and Bakken shales.
