Introduction to Fiber Optic Distributed Temperature, Acoustic, and Chemical Sensing  (DTS,  DAS, & DCS)
Reservoir Descriptions and DynamicsProduction and Operations

James J. Smolen


This one-day course is an introduction to the emerging fiber optic technologies of Distributed Temperature Sensing (DTS) as well as related Acoustic (DAS) and Chemical (DCS) sensing.  This program looks at how these technologies work, and their application to  the oil and gas industry.   Such systems have been utilized in shallow steam injection wells as well as high-cost horizontal and multilateral wells where re-entry with a logging tool is difficult , if not impossible.  This class also includes an overview of PLATO software for managing DTS data and computing flow, plus a hands-on demonstration of DTS hardware.  Topics include: 

  • How DTS, DAS, and DCS technologies work 
  • Typical well installations, hardware, and log recordings 
  • Factors affecting data accuracy, calibration, and quality 
  • Field applications and examples of DTS and DAS 
  • PLATO software for DTS data management and computation of flow profile 
  • DTS demonstration

Why You Should Attend

The science behind DTS and its applications are still emerging. If you have been following this technology and would like to learn more, this course is for you.

Who Should Attend

This course is for petroleum engineers, geologists, and anyone else interested in learning more about DTS and the latest advances in the technology.
