N481 Fiber-Optic Sensing: Introduction to the Technology and In-Well Sensing Applications

Course Facts

Course Code:
1 days
0.8 Continuing Education Units
8 Professional Development Hours
Certificate Issued Upon Completion


This course introduces petroleum engineers and geoscientists to fiber-optic sensing technology that is used for well and reservoir diagnostics and surveillance. It provides in-depth technology awareness, including underlying theories of operation and breadth of well and reservoir applications, and the basic tools to determine whether fiber-optic sensing has the potential to address key well and reservoir uncertainties. The engineer and geoscientist will leave with an understanding of how fiber-optic sensors work, and how to use that knowledge to define where and how fiber-optic sensing can create value for specific well and reservoir types.

Duration and Training Method

N481 is a one-day classroom based course. Training consists of lectures, class discussion, exercises and case histories.

Participants will learn to:

1.  Determine cases where fiber-optic sensing can provide data to optimize completion and stimulation design and improve hydrocarbon recovery.
2.  Compare and contrast fiber-optic sensing relative to other diagnostic and surveillance monitoring methods.
3.  Evaluate predicted well production/injection performance to assess efficacy of DTS, DAS, stand-alone single-point fiber-optic sensors and sensor arrays.
4.  Screen well completion and reservoir development scenarios using technical and economic analyses.
5.  Apply simple cost:benefit models for fiber-optic data acquisition in  specific well types.
6.  Build project plan outline for start-to-finish FO data acquisition system design, vendor and equipment selection, data management and interpretation.

  • What is Fiber-Optic Sensing (FOS): basic physics and engineering of the FOS system components: fibers, coatings, cabling, connectors optical fibers, sensor types, instrumentation.
  • Why we would want to use FOS: advantages and disadvantages vs. other sensing/monitoring technologies.
    • Single-point FO sensors: P, T, seismic/acoustic
    • Distributed FO sensing:  temperature (DTS), acoustics (DAS), strain (DSS)
  • Overview of the different applications
  • Survey of FOS system deployment methods
    • Permanently installed FOS
    • FO “logging” interventions & temporary installations
  • Data management and analysis/interpretation
  • Factors that influence FOS system selection
  • High-level screening of candidate wells and justification for installing FOS.

Who should attend

This course is designed for petroleum engineers and geoscienctists who want an understanding of how fiber-optic sensors work and how to use that knowledge to define where and how fiber-optic sensing can create value for specific well and reservoir types.

Prerequisites and linking courses

A basic understanding of physics and petroleum engineering is required.  The follow-on, skilled application course is N473, Fiber-Optic Sensing:  Diagnostic and Surveillance Applications and Deployment.
