The BroadBand Sequence fracturing technique sequentially isolates fractures at the wellbore to ensure every cluster in each zone is fractured and can contribute to the well's full potential. The BroadBand Sequence technique maximizes well productivity and improves completion efficiency while significantly reducing completion hardware and overall completion costs.
Each zone is sequentially isolated, fractured, and fully stimulated, resulting in more reservoir volume and greater contact. By temporarily locking and unlocking clusters, the composite fluids are diverted to higher stress regions for increased fracture stimulation within each stage. The composite fluid degrades, depending on the temperature of the well and downhole conditions, restoring full fracture conductivity.
The BroadBand Sequence technique enables the treatment of longer intervals and additional fracture clusters, while reducing the amount of bridge plugs needed for completing the well. When using the Broadband Sequence technique, operators working in tight sandstone, carbonate, and shale reservoirs experienced increased efficiency and a reduction in the number of bridge plugs needed per completion.
