BroadBand Sequence

Fracturing service for efficiency in limited-entry completions

Access more reservoir volume and ensure every perforation cluster delivers its full production potential

The BroadBand Sequence fracturing service sequentially isolates fractures at the wellbore to ensure every cluster in each completion zone is fractured and can contribute to the well's full potential. The BroadBand Sequence service maximizes well productivity and improves completion efficiency while significantly reducing completion hardware and overall completion costs.

Maximize stimulated volume in wells with limited-entry completions

Each zone is sequentially isolated, fractured, and fully stimulated, resulting in more reservoir volume and greater contact. By temporarily locking and unlocking perforation clusters, the engineered composite pills divert fluid to higher stress regions for increased fracture stimulation within each stage. Each composite pill then degrades at downhole temperatures and conditions, restoring full fracture conductivity.

When the BroadBand Sequence service is used to stimulate additional clusters (blue), it provides more accurate results than the highly variable ones produced by conventional stimulation techniques.

Reduce completion cost and minimize plug-and-perf stages in initial completions and refracs

BroadBand Sequence service treats longer intervals and additional fracture clusters while reducing the number of frac plugs required to complete the well.

When using the Broadband Sequence service for initial fracs in new wells or refracs in mature wells, operators working in tight sandstone, carbonate, and shale reservoirs experienced increased efficiency and a reduction in the number of bridge plugs needed per completion.

Stimulate long intervals efficiently with composite pills engineered for your well conditions.

A composite pill of degradable particles and fibers

The BroadBand Sequence fracturing service features engineered composite pills comprising a proprietary blend of degradable particles with tetramodal size distribution and fibers. The pill is designed so that the large particles are intercepted at the entrance of a fracture, while smaller particles reduce permeability to create temporary isolation. The fibers ensure the integrity of the blend from surface to near-wellbore area and enhance the bridging mechanism.

Improve near-wellbore conductivity with a partially degradable pill

An enhanced-conductivity pill blends degradable particles and highly conductive spheres chosen to enhance diversion strength and ensure near-wellbore conductivity. They are combined with degradable fibers, which prevent dispersion of the particles to ensure consistent isolation. After treatment, the particles and fibers fully degrade, leaving the spheres in the near-wellbore area to ensure superior well connectivity to the extended fracture and reservoir.

Improve diversion performance in conventional reservoirs

Conventional reservoirs will benefit from an engineered dynamic diversion pill that combines multimodal degradable multimodal particles, fibers, and nondegradable particulates. Degradable fibers function as a suspension agent for particles and help to maintain pill integrity during delivery. This conventional reservoir diversion pill is designed to improve diversion efficiency by minimizing fluid loss into open fractures and increasing the pressure differential to promote initialization of additional fractures in higher-stress areas of the formation.
