More recently, specially engineered solid particulate diverter systems have been developed with optimal particle size distribution and longer dissolution times. These newer diverters help enable far-field diversion, which creates more complex fracture networks by temporarily plugging the main fracture to allow the fluid and proppant to extend into the far—and smaller—reaches of the fracture network. However, one challenge that has remained is that the dissolving diverters create voids in the proppant pack that can close or “choke” the fracture in the near-wellbore area and restrict production.
The Baker Hughes REAL Divert Complete system provides temporary diversion to ensure complete stimulation of all perf clusters and targeted zones. This proprietary diversion system is effective in both initial hydraulic fracture treatments and refracturing applications, delivering near-wellbore diversion.
Improve stimulation effectiveness and fracture complexity
Due to the broad particle size distribution, the REAL Divert Complete system provides effective near-wellbore temporary blockage in cased-hole applications—redirecting the frac fluid’s flow to the perforation clusters and reservoir sections, where it is needed for maximum stimulation performance.
The diversion materials in the system are fully degradable and soluble in both hydrocarbons and water-based fluids, while the rate of dissolution is sufficiently low to allow mixing and pumping without degradation of the REAL Divert Complete system.
These materials ensure that the temporarily blocked areas remain open for optimal hydrocarbon flow after the diversion material has fully dissolved. The result: conductive flow paths permanently connecting the well to the reservoir.
REAL Connect services effectively: ensure optimal treatment of all perforation sets; increase fracture network complexity/coverage; maximize total recovery; accelerate stimulation operations; enable horizontal multi-stage refracturing treatments.
The REAL Divert Complete system is engineered for use in applications ranging from 100° to 250°F (38° to 120°C). The REAL Divert HT system is engineered for use in high-temperature applications ranging from 200° to 350°F (93° to 177°C).
Create and connect your well to permanent hydrocarbon flow paths
The Baker Hughes REAL Connect service leverages state-of-the-art diverter systems to redirect your frac fluid flow to the perforation clusters and reservoir sections where it is needed for maximum stimulation performance. Then, once the stimulation treatment is complete, it maintains the production flow paths—completely and permanently.

Redirect frac fluids to untreated perf clusters and reservoir zones
Like all liquids, fracturing fluids want to follow the path of least resistance. In unconventional reservoir stimulations, this can result in overtreated zones, untreated perforation clusters within a stage, and suboptimal reservoir contact. However, it is possible to increase fracture network complexity and ensure more uniform coverage with specially sized diverter material that blocks off the path of least resistance and redirects the frac fluids to untreated perforation sets within the stage.
These diverter systems help accelerate stimulation operations through the placement of more perforation sets per stage by combining stages and reducing the number of plugs required for isolation. They can also boost treatment effectiveness and recovery by increasing fracture network complexity and coverage within unconventional. These diversion technologies help rejuvenate mature wells through effective refracturing treatments.
Preserve optimal hydrocarbon flow into the wellbore
Complete system to deliver effective, efficient, and productive diversion—without the risk of collapsed or choked hydrocarbon pathways. The system combines the following:
REAL Connect technologies with a broad particle size distribution that provides diversion of frac fluids to untreated perf clusters and reservoir zones;
Specially engineered and strong lightweight proppant particles that ensure high conductivity in the near-wellbore area. Ultra-lightweight proppant ensures all flowpaths remain fully open after the diversion material has dissolved.
The REAL Divert Complete system’s diversion materials remain fully degradable and soluble in both hydrocarbon- and water-based fluids so they clean up completely after the stimulation treatment.
With the integration of lightweight proppant particles, the system ensures that the temporarily blocked perforation clusters remain open for optimal hydrocarbon flow throughout the life of the well.
Unlike conventional diverter material, which dissolves completely and does not leave anything behind to stop the formation from healing over time, the REAL Divert Complete system incorporates strong lightweight proppant to help keep production pathways open completely and permanently. The first image above shows the initial REAL Divert Complete system as deployed with dissolvable diverter. The photograph below shows the remaining conductive proppant pack, which allows for unrestricted hydrocarbon flow.
Demand a diversion methodology that redirects your frac fluid flow to the perforation clusters and reservoir sections where it is needed for maximum stimulation performance, and then, once the stimulation treatment is complete, ensures that those paths remain open completely and permanently for maximum hydrocarbon flow.
To maximize recovery, choose the Baker Hughes REAL Connect service for your next unconventional stimulation treatment.
