An autonomous injection control device that limits the flow of injected fluids into high permeability (thief) zones

Page last modified

March 10 2025

The FloFuse Injection valve is an autonomous injection control device that limits the flow of injected fluids into high permeability (thief) zones, and natural or induced fractures, to ensure effective flow distribution in fractured or highly heterogeneous reservoirs.

This device is a biased open valve which enables water injection at normal distribution rates but closes once a trigger flow rate through the valve is exceeded, analogous to a circuit breaker in an electrical distribution network. When combined with a FloExtreme Injection ICD, restricted injection can be sustained in the target zone even when the FloFuse valve has been triggered closed.

FloFuse Injection delivers:

effective autonomous response to unanticipated or changing injectivity conditions
improved reservoir sweep
reduced water production

Pros & Limitations

Control the velocities

High DP

Control extensive thief zones

High flow rate

Balancing the injection profile

Control short circuiting from injector to producers

You will produce less water

Specification

Specification Title	Specification Description
Asset Life Extension	Optimises oil production over the life of a well by delaying water break-through and reducing oil-gas ratios
Flexibility	Interchangeable with any combination of inflow/outflow control valves to minimise inventory and allow flexibility on final completion design
Deployment	Deployed as part of the lower completion or retrofitted into an existing well, mounted with a sub or integrated with sand screens.
Integrations	Can be integrated with sand control screens for soft formations
