Ensure effective flow distribution in fractured or highly heterogeneous reservoirs

Page last modified

June 17 2024

FloFuse Injection

Distribution of injected fluids is critical for achieving effective oil sweep or chemical treatment. The presence of highly permeable zones or fractures prevents effective fluid distribution leading to lower recovery factors and premature water breakthrough in production wells.

FloFuse Production

Designed to limit the liquid rate from a highly fractured section in the reservoir. A high water rate will compress the disc to fuse and choke the flow. The valve remains dynamically reactive and will re-open if the distributed flow can be achieved.

Pros & Limitations

Works autonomously downhole

Rates are engineered for optimal performance in each application

Improves reservoir sweep efficiency

Delays water breakthrough in producers

Restricts injection into fractures

Ensures uniform injection

Improved placement of acid / treatments

Field adjustable

Limited previous deployment outside the Middle East & US

Specification

Specification Title	Specification Description
Asset Life Extension	Allows effective fluid distribution leading to higher recovery factors and reduced water breakthrough in production wells.
Flexibility	Deployed as part of the lower completion or retrofitted into an existing well, mounted within a sub or integrated with sand screens.
Optimisation	Trigger rates are engineered for optimum performance in each application. The valve remains dynamically reactive and will re-open if distributed flow is achieved.
Safety	This device is a biased open valve which enables water injection at normal distributed rates but chokes once a trigger rate is exceeded.
Automation	Autonomous injection control device that limits the flow of injected fluids into thief zones to ensure effective flow distribution in fractured or highly heterogeneous reservoirs and limit the liquid rate from a high fracture section in the reservoir.
