Reservoir Flow

Provides flow profiles behind casing at the well-to-reservoir interface

Reservoirs are the ultimate source and destination of flow for producers and injectors. The wellbore is just a passing place. Ensuring productivity means looking beyond the wellbore, into the reservoir itself.


Reservoir Flow complements conventional wellbore flow diagnostics by evaluating flow profiles behind casing at the well-to-reservoir interface.


Delivered by our True Flow system using the Chorus (acoustic) platform and the Cascade (thermal) platform; Reservoir Flow provides the information needed to manage well system performance more effectively.


Reservoir Flow is commonly used to diagnose unexpected or undesirable well system behavior, but it can also be used proactively to ensure the well system is working optimally. Our Total Flow product should be used for a more complete diagnosis.

  • Evaluate flow profiles at the reservoir layers
  • Unexpected change in production or injectivity performance
  • Unexpected water or gas breakthrough
  • Suspected cross-flow behind-casing
  • Input for recalibrating reservoir model
  • Reservoir flow assessment and characterisation


  • Understand the true sources of production and assess flow profiles qualitatively
  • Know where injection fluids are going and assess flow profiles
  • Identify cross-flow and thief zones
  • Locate source of water or unwanted gas
  • Identify field development opportunities
  • Understand natural fractures
