Increase production and recovery with improved wellbore coverage
The BroadBand Precision integrated completion service maximizes oil production and recovery by ensuring every fracture is stimulated and propped open from the tip of the fracture to the wellbore. Every promising perforation cluster in each interval is stimulated and proppant coverage is maximized across all fractures to create flow paths for hydrocarbons.
Control fracture placement and reservoir contact
The BroadBand Precision service enables maximum control of fracture placement, sizing, and conductivity. Through the use of cemented frac sleeves, every cluster along the lateral is fractured with accuracy and efficiency. Each fracture is propped open from tip to wellbore using an engineered composite fluid to deliver increased production and recovery.
Ensure more efficient unconventional operations
Efficient operations are important to ensure economic success in unconventional reservoir plays. By coordinating multiple services into one offering, the BroadBand Precision service offers seamless operations. Operational efficiency is improved by controlling fracture placement to reduce water, proppant usage, and horsepower for productive stimulation treatment and reduced operational footprint. The integrated modeling and measurement data is used to optimize the stimulation design. A single point of contact in the office or on location ensures strong customer support every step of the way.
Fracturing fluids improve proppant transport and placement
Engineered composite fracturing fluids enable channels to connect far-field areas with the wellbore, increasing the volume of fractures effectively contributing to production. The fluids enable proppant transport to maximize coverage in the fracture and mitigate settling, thus promoting the formation of high-conductivity flow channels across all fractures to their total depth and height.
Composite Fracturing Fluids
Composite fracturing fluids are combinations of proprietary fibers, fluid additives, and proppant used as part of the BroadBand* unconventional reservoir completion services to enhance reservoir contact. The composite fracturing fluids maximize proppant transport and placement. Compared with conven?tional fracturing fluids, the composite fracturing fluids transport proppant across turns and corners within the complex fracture network to effectively stimulate a larger fractured area. Short sweeps of clean composite fracturing fluids are applied to mitigate proppant buildup in the near-wellbore area, thus reducing the risk of screenouts and proppant flowback. Once pumping ceases, proppant is suspended in the fracture by using degradable fibers, which hinder settling and promote heterogeneous distribution of proppant across each fracture in its entire height and length. The result is a robust, highly conductive hydraulic fracture for maximized oil and gas production and recovery.
Cemented sliding sleeve enhances accuracy and efficiency
The fullbore sliding sleeves cemented in the well casing string enable on-command opening and closing of each entry point in the completion hardware. This control, which is not offered by any preceding sleeve in the industry, allows every prospective cluster along the lateral to be stimulated individually with accuracy and efficiency.
Stimulation design integrates modeling and measurements
Integrated workflows combine modeling and measurement data to optimize the placement of fractures and maximize reservoir contact. The Mangrove engineered stimulation design in the Petrel platform enables smarter completion design to help ensure only promising fractures are stimulated to promote the economic viability of your reservoir.
BroadBand Services’ Composite Fracturing Fluid Enables 64% Increase in Oil Production
Operator experiences poor fracture coverage using slickwater
Comprising sandstone layers separated by carbonaceous and shaly siltstones, the Bone Spring Formation is primarily developed using horizontal wells with multiple fractures. For a particular well, an operator needed to maximize the proppant amount per foot of lateral while reducing the fracture face damage caused by polymer presence in the fracturing fluid. Slickwater, while less damaging than other fluids, is an ineffective fluid transporter that leads to proppant settling on the fracture bottom close to the wellbore. Its use had led to poor fracture height coverage and limited the formation-to-fracture contact areas, which are essential for production in tight formations.
Schlumberger deploys composite fracturing fluid to effectively stimulate well
To resolve the issue, Schlumberger proposed using BroadBand services’ composite fracturing fluid, which features next-generation fibers and is applied in high-frequency sweeps to minimize potential screenouts. A total of 32 fracturing stages out of 33 were pumped with the service’s composite fracturing fluid—80% slickwater tailing with 10-lbm linear gel—with 2 lbm of proppant added per gallon of fluid. Additionally, asymmetric pulses—30 seconds of slurry for every 10 seconds of clean fluid—were applied.
Effective proppant placement improves well production
The well was stimulated as designed, and no operational issues were reported. In comparison with offset wells treated with similar amounts of proppant and water, the well treated with BroadBand services’ composite fracturing fluid had effective vertical proppant distribution with an enlarged reservoir contact area, which led to a 64% production improvement over that of the best-performing offset well. Due to the success of this operation, the operator plans on using BroadBand services’ composite fracturing fluid when developing future wells in the Bone Spring Formation, Permian basin.
