Continuing improvement in oil well fracturing methods increases production level by 20% and nearly halves the time to complete some steps in well creating

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.

The BroadBand Sequence fracturing technique has enabled customers in South Texas 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-perf 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.

BroadBand Sequence is the first release of a family of BroadBand completion technologies aimed at maximizing well productivity in unconventional reservoirs.
