COURSE OVERVIEW

This practical and highly-interactive course includes real-life case studies and exercises where participants will be engaged in a series of interactive small groups and class workshops. 

 

Distributed Temperature Sensing (DTS) is an amazing and somewhat new technology through which temperature surveys can be taken non-obtrusively in a well. In another words, a logging tool never goes downhole. A temperature log is recorded continuously along the well depth in real time and at time intervals as small as a few minutes between surveys. This time lapse monitoring capability allows an otherwise difficult-to-interpret temperature log to easily pinpoint production changes. 

 

These DTS systems use a fiber optic line placed in a well typically as a semi permanent installation along the well length. Such systems have found application in high cost horizontal and multilateral wells where re-entry with a logging tool is difficult if not impossible. They are also commonly used in shallow steam injection environments to monitor steam breakthrough in producing wells.  Recent years have also witnessed the emergence of Distributed Acoustic and Chemical Sensing, DAS and DCS respectively. These new technologies offer significant new insights into production and reservoir management. 

This course is an introduction to the emerging fibre optic technologies of Distributed Temperature Sensing (DTS) as well as related Distributed Acoustic (DAS) and Distributed Chemical Sensing (DCS). This programme looks at how these technologies work, and their application to the oil and gas industry. Such systems have been utilised 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.
