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

Course Code: N481
Instructors:  Dennis Dria
Course Outline:  Download
Format and Duration
1 days


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.

Course Overview

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.
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.

Dennis Dria

Dennis Dria is president and petroleum technology advisor for Myden Energy Consulting, PLLC (2010-present). He has 39 years of experience in the oil & gas industry, including 9 years with the Standard Oil Company and 21 years with Shell, in a combination of upstream and downstream oil and gas R&D and E&P operating division positions. At the time he left Shell in 2010, he was a Staff Research Engineer working in the areas of fiber-optic technology development, fiber-optic data management and integration and technology implementation for well and reservoir monitoring. Prior to this he was Engineering Advisor for Shell’s Global Implementation Team for Reservoir Surveillance Technologies during which he identified appropriate in-well monitoring technologies for Shell "top 70" global development projects, resulting in field surveillance plans for more than 20 major E&P projects. He also was Shell’s Global Subject Matter Expert (SME) for Production Logging and Permanent Sensing and SME for Mud Logging, and had formation evaluation and well logging (open-hole and cased-hole) assignments that included planning, vendor selection, operations, interpretation and field studies.

Under Myden Energy Consulting, PLLC, Dennis advises clients on the "right-fit" technology to provide key data and information which result in actionable recommendations for appropriate implementation timing and methods, and assists in deployment, data management, information extraction and interpretation. He has completed consulting projects for more than 20 industry clients, including onshore unconventional gas and oil, deep-water dry tree and subsea wells/fields, and has developed and taught multiple fit-for-purpose short courses. Additionally, he has provided well logging/MWD vendor selection, job planning, and operational supervision for Midland Basin and Delaware Basin (Texas) unconventional field development.
