True Flow Products
Fibre Flow

Locate and quantify flow in the well system with fibre optics

More and more wells are fitted with distributed temperature (DTS) fibre to monitor performance or are using hybrid fibre optic cables for logging. However, DTS alone cannot provide a complete picture of flow dynamics in the well system. The addition of distributed acoustic sensing (DAS) can change that for the better.


But, making sense of DTS and DAS data and activating the well to reveal its actual flow performance isn’t easy for traditional systems.


Fibre Flow brings all the benefits of our Total Flow product to wells using fibre optics, to tell the whole flow story, from the reservoir to the wellbore.


Delivered by our analysts using the True Flow system with Cascade technology and advanced acoustic processing and analysis, Fibre Flow provides the clarity and insight needed to manage well system performance more effectively.


Fibre Flow is often used to diagnose unexpected or undesirable well system behaviour, but it can also be used proactively to ensure the well system is working optimally – both in terms of flow performance and integrity.


The combination of both DTS and DAS technology incorporated within Fibre Flow delivers a whole new level of well system diagnostics.
