Distributed Temperature Sensor (DTS)
Tendeka offers the widest range of Distributed Temperature Sensing (DTS) options, with the most advanced and reliable performance available on the market today. Our range of DTS solutions ensures that your every monitoring requirement is met. Depending on your specific needs, we can measure temperatures to a resolution of better than 0.01°C, at every second, at every metre along fibre optic cables up to 60km long (per DTS). The system is packaged in a standalone unit with an onboard PC, and operates with a user-friendly software interface, making it an easy-to-use and easily transportable system.
DTS downhole applications
Distributed Temperature Sensing allows many reservoir management challenges faced in declining fields, complex well profiles and completion methodologies to be addressed including:
• Well integrity issues (e.g. leak detection and gas lift optimization)
• Flow allocation from temperature profiling
• Injection allocation
• Cross flow verification and monitoring & inflow/injection valve operation
• Stimulation performance and effectiveness
• Steam flood performance
Advantages of DTS
Distributed Temperature Sensors have numerous advantages including the following:
• Fully distributed data greatly increases information and reduces uncertainty
• Sensor is made from standard optical fibre (cost effective)
• Immune to shock/vibration and electromagnetic interference
• No electronics or moving parts in monitoring zones
• Inherently high reliability (sensor design life of >30 years)
• High temperature performance of up to 650°C
• Extremely small for access into space restricted areas
• Easy to install – either permanently or by intervention methods.
