Distributed Fibre Optic Sensing

A new era in well integrity

A new era in well integrity

From evaluation to remediation, we can give you a more in-depth insight into your well.

Monitoring oil and gas wells requires state of the art sensing technologies. Fibre optic has become an increasing part of surveillance in the industry, which has been driven by technological enhancements and greater knowledge of what it can do.

Surveillance is a key input into any aspect of successful well and reservoir management. Our Distributed Fibre Optic Sensing (DFOS) gives us the capability to monitor your entire well. It enables us to manipulate surface conditions to observe dynamic behaviours in the well, giving you a more accurate diagnosis of your well and reservoir issues.

Compared to traditional methods, our DFOS analyses well performance and integrity within hours, to help you make important time-sensitive decisions. Supported by DFOS, we can provide an enhanced cased hole offering and integrated slickline mechanical services all within Expro. We work as one team to extend your wells' lifespan while reducing time and costs.

Applications:

  • Leak detection
  • Behind casing crossflows
  • Artificial lift assessment
  • Sand production

Features/Benefits:

  • Fibre is thin, low cost, and is resistant to hostile environments
  • Monitoring dynamic behavior in wells
  • Ability to extract value from fibre to manage your wells/reservoirs or help in influencing decisions
  • Rapid turnaround of data enabling remediation services to take place during the same rig up or intervention
  • Ease of use
  • Fast processing
  • Effective well/reservoir management
  • Reliable performance in both HPHT and hydrogen rich environments
  • Gives a clear picture of what is happening and allows you to react instantly
