Schlumberger 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 BroadBand Sequence 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.
“Optimizing the stimulation of wellbore perforation clusters in unconventional reservoirs is a significant challenge for our industry,” said Amerino Gatti, president, Well Services, Schlumberger. “The BroadBand Sequence technique addresses this challenge and increases our customers’ well production by enhancing stimulation contact in every zone in the reservoir.”
This fracturing technique 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.
