Locates and quantifies flow in a fibre optic completion

More and more wells are fitted with distributed temperature (DTS) fibre to monitor performance, or are using slickline fibre optic cables for logging. But, making sense of the 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 True Flow system using the Cascade (thermal) platform; Fibre Flow provides the clarity and insight needed to manage well system performance more effectively.

Fibre Flow is commonly used to diagnose unexpected or undesirable well system behaviour, but it can also be used proactively to ensure the well system is working optimally.

Challenges

Quantify flow profiles in well systems with fibre optic DTS sensing or using slickline fibre optic cables
Poor production or injectivity performance
Unexpected change in well system performance
Unexpected water or gas breakthrough
Suspected cross-flow in wellbore or behind-casing
Recalibrating reservoir model
Reservoir flow assessment and characterisation

Benefits

Understand the true source of production and quantify flow profiles accurately
Know where injection fluids are going and quantify flow profiles accurately
Identify cross-flow and thief zones
Locate source of water or unwanted gas
Better well and reservoir management decisions, precisely targeted
Improve well system performance and extend productive life of asset

Well sketch shows a range of flow scenarios that Fibre Flow can locate and quantify.

Indicative logplot for Fibre Flow Log plot shows a fish-hook injector well where the objective was to define the formation injection profile in the horizontal section (Zones 4, 5, and 6). QZI indicated modelled static temperature and formation injection profile. QZ shows the total injection rate: 390 m3/d. Smooth-shaped static temperature gradient between Zone 3 and 4 indicates communication between them. Zone 3 absorbs 3% of total injection rate.
