ResInject

Applications

• Injection wells requiring flow control
• Openhole stand-alone screen completions
• Homogeneous and heterogeneous sandstone and carbonate reservoirs
  

Benefits

• Ensure uniform distribution of injected fluid to improve sweep efficiency and increase hydrocarbon recovery
• Redirect injection fluid away from high-permeability zones, increasing reservoir contact and delaying injection fluid breakthrough in production wells
• Reduce unit development costs and interventions
• Simplify injection management across multiple openhole zones
• Optimize nozzles at the wellsite, based on log data
  

Features

• Fixed pressure drop achieved through ceramic nozzle
• Robust construction validated through flow, erosion, and mechanical integrity testing
• No requirement for downhole telemetry, cables, or control lines
• Multiple options for screen media
  

How it improves performance

ResInject™ injection ICDs balance injection profiles across the wellbore. They enhance sweep efficiency by redirecting injection fluids toward lower-permeability zones that would otherwise receive limited injection. This functionality promotes greater reservoir contact, improves oil displacement, delays injection fluid breakthrough at production wells, and increases ultimate recovery. The ICD’s robust, self-regulating design reduces operational complexity, enhances well integrity, and minimizes the need for costly well interventions throughout the life of the injection well.

How it works

Injection fluids enter the ResInject device and exit through the ceramic nozzle. The injection ICD is engineered to restrict flow into higher-permeability zones. Consequently, lower-permeability intervals receive a proportionally larger share of the injection fluids. This dynamic behavior maintains a balanced injection profile despite reservoir heterogeneities. The system integrates seamlessly with sand control screens.

What it replaces

ResInject injection ICDs replace conventional screens used for openhole injection, which allow uneven fluid distribution, resulting in poor sweep efficiency and early injection fluid breakthrough. The ICDs provide self-balancing injection control throughout the wellbore.
